Gaia Pigino studies the molecular mechanisms and principles of self-organization in cilia using 3D cryo-EM.

Gaia Pigino was only 3 yr old when she became fascinated with nature in the beautiful countryside of Siena, Italy, where she grew up. The neighbor’s daughter showed her a hen in the chicken coop, and they caught it in the act of laying an egg. Gaia remembers, “This was for me almost a shock, as my experience about eggs was that they come directly out of paper boxes!” Her father was also an important part of awakening Gaia’s curiosity for the amazing things in nature. He used to bring home the award-winning magazine Airone, the Italian equivalent of National Geographic. Gaia never missed an issue; even before learning to read, she could spend hours looking at the captivating photos of the wildlife. She wanted to understand what she was seeing, and maybe because of that, she was determined to do science.Gaia Pigino. Photo courtesy of Human Technopole.Gaia took her first “scientific” steps with Professor Fabio Bernini and Professor Claudio Leonzio at the University of Siena, where she studied bioindicators of soil contamination and detoxification strategies of soil arthropods as part of her PhD project. But it was later, when she joined the laboratory of Professor Pietro Lupetti and met Professor Joel Rosenbaum, a pioneer of cilia research, that Gaia discovered the world of 3D EM and felt her place was “inside a single cell.” She solidified her interest in the structure of protein complexes of cilia and flagella and boosted her passion for cryo-electron tomography (ET) in the laboratory of Professor Takashi Ishikawa, first at the ETH Zurich and then at the Paul Scherrer Institut in Switzerland. In 2012, Gaia started her own laboratory at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany, with the vision of creating a truly interdisciplinary laboratory. Her team combines techniques from different fields such as biophysics, cell biology, and structural biology to answer open questions in the cilia field. Gaia recently moved countries again—this time to take over the position of Associate Head of the Structural Biology Research Centre, at the Human Technopole, Milan, Italy.We reached out to Gaia to learn more about her scientific journey and future research directions.What interested you about cilia?The first thing that attracted me toward cilia and flagella were some EM micrographs, by Professor Romano Dallai in Siena, that showed the beautiful geometrical microtubular structures of sperm flagella. I was intrigued by the apparent perfection of these organelles that clearly showed me that a cell is a coordinated system of complex molecular machines, the mechanism of many of which we do not understand. Soon after, Professor Joel Rosenbaum introduced me to the bidirectional transport of components inside cilia, which, he explained to me, is required for both assembly and function of virtually all cilia and flagella, from the motile cilia in our lungs to the primary cilium in our kidneys. He called it intraflagellar transport (IFT) and compared it to a Paternoster elevator, where the individual cabins were what we now call IFT trains. I was completely fascinated by the IFT system, the structure, the function, the dynamics, and the mechanism of which were still largely unknown. Quickly, I realized that in addition to IFT, cilia represent a virtually infinite source of open biological questions waiting to be solved, from the mechanics and regulation of the beating to the sensory function of primary cilia, and their importance for human health.What are some of the scientific questions currently of interest in your laboratory?In the past few years, we have made substantial contributions to the current understanding of the structure and the mechanism of the IFT (1, 2, 3). Currently, we are investigating how the structure of IFT trains relates to their functions by looking, in cryo-electron tomography, at how anterograde trains transform into retrograde trains and at how different ciliary cargoes are loaded on the trains. Beside this more classical line of research, we are exploring other approaches to study IFT, for instance we have developed a method to reactivate IFT trains in vitro on reconstituted microtubules. We want to use this approach to investigate the behavior of IFT trains, and their motors, in experimentally controllable conditions, e.g., in the presence of only certain tubulin posttranslational modifications. We have also made interesting discoveries about the distribution of tubulin posttranslational modifications on the microtubule doublets of the axoneme and how this spatially defined tubulin code affects the function of different ciliary components. We hope we will be able to share these new “stories” with the structural and cell biology community very soon!What kind of approach do you bring to your work?I believe that the main reason for why science became an integral, and dominant, part of my life is because it provides infinite riddles and continuous challenges. I have always been curious about how things work in nature, but I quickly realized that learning from books didn’t satisfy me. My desire was to be at the frontline, to be among the ones that see things happening in front of their eyes, at the microscope, for the first time. I wanted to be among the ones that make the discoveries that students read about in textbooks. Thus, what I bring to my work is an endless desire of solving biological riddles, curiosity, creativity, determination, and energy, with which I hope to inspire the members of my team. My laboratory uses an interdisciplinary approach; we use whatever method, technique or technology is needed to reach our goal, from the most basic tool to the most sophisticated cryo-electron microscope. And if the method we need does not yet exist, we try to invent it.A young Gaia Pigino (3 yr old) the day she discovered how eggs are made. Photo courtesy of Giancarlo Pigino.Could you tell us a bit about the Structural Biology Research Centre at the Human Technopole (HT)?At the HT Structural Biology Centre, we are working to create a vibrant and interdisciplinary scientific environment that will attract molecular, structural, cell, and computational biologists from all over the world. We are creating fantastic facilities, including one of the most well equipped and advanced electron microscopy facilities in Europe—and likely the world—headed by Paolo Swuec. My team, together with the teams of my colleague Alessandro Vannini and the research group leaders Ana Casañal, Francesca Coscia, and Philipp Erdmann, already cover a vast range of competences and know-how from classical molecular and structural biology approaches, such as crystallography and protein biophysics, to cryo-CLEM, cryo-FIB SEM and cryo-ET, all of which allow us to address questions in cell biology. Our goal is to create a scientific infrastructure and culture that will enable biologists to obtain a continuum of structural and functional information across scales.What did you learn during your PhD and postdoc that helped prepare you for being a group leader? What were you unprepared for?I learned that everyday research is mostly made of failures, but that with the right amount of obsession, persistence, curiosity, and creativity, it is always possible to succeed and discover new things. Being given the freedom to develop your own ideas and your own project very early in your career is a treat; science is not only about having good ideas! One needs to follow up on these ideas with intense work and troubleshooting to make them reality. In addition, I realized that being fearless and attempting what is considered too difficult by others, despite challenges, can turn into a worthy learning experience. Also, how you present your work to the scientific community matters for swinging the odds of success in your favor. Different places might work in very different ways, and conducting good science does not only depend on you, but also on the possibilities given to you by your environment.What was I unprepared for?—I guess several things, but one comes immediately to mind: I underestimated how much being responsible not only for my own life and career, but also the career of students, postdocs, and others in the laboratory, would affect me personally.Structure of the 96-nm axonemal repeat reconstructed by cryo-ET and subtomogram averaging. Image courtesy of Gonzalo Alvarez Viar, Pigino Lab.What has been the biggest accomplishment in your career so far?This is a tricky question for me... I tend to look into the future more than celebrating the past. I fight to succeed in something, but as soon as I conquer it, I find it less of an achievement than the thing I could conquer next. Nevertheless, I am happy about the discoveries and the papers published together with my students and postdocs (1, 2, 3, 4, 5). I am extremely excited about the fact that after many years of work I am now leading an interdisciplinary laboratory, where we combine techniques from different fields. I am also happy that three times my husband and I were able to move from one world class academic institution to the another to start exciting and fitting jobs and could still live together in the same place. We worked hard for this, but we also got lucky.What has been the biggest challenge in your career so far?I studied French in school; I had almost no exposure to spoken English until the end of my PhD. To avoid having to show my English insufficiencies, I did hide beside the board of my poster at the first international conference I attended in 2004! It took me a while to overcome this barrier and feel confident to express my thoughts and ideas in English.What do you think you would be if you were not a scientist?I had been a good fencer during my youth. I was a member of the Italian National Team between ages 14 and 19 and saw quite a bit of the world, which was cool! When my sporting career failed, due to diabetes, I was torn between art and science. I guess that in a parallel universe, I am a wildlife photographer and a potter specialized in wood kiln firing. [Gaia confesses that she misses “the amazing and addictive adrenaline rush of a good fencing match!”]Any tips for a successful research career?Do not compare your performances to the ones of the people at your career stage; compare yourself with people that are already successful one level higher than you currently are at. For example, if you are a PhD student, ask yourself what in your current performance separates you from being a good postdoc—once a postdoc, what is missing to be a good PI.  相似文献

No one maps out their tenure as a postdoc anticipating a life-altering tragedy. But mental health crises of all kinds affect academic trainees and staff at similar or higher levels than the general public. While the mental health resources available to trainees are often set by healthcare providers, all levels of university leadership can work to remove material and immaterial obstacles that render such resources out of reach. I describe how access to care via telemedicine helped me following a loss in my family.

Over the years, my siblings and close friends have sought mental health resources like therapy, psychoanalysis, or psychiatry, so I loosely understood their benefits. When I was a PhD student I went to therapy briefly, but my counselor and I decided I could do without it. Since I started my postdoc, stress manifested in some new ways but I managed it well with my usual coping strategies and support. That changed one bright December morning in 2019 while I was preparing for our weekly lab meeting. My phone rang indicating a call from my father, whom I had spoken to the night before to celebrate the news of my nephew’s birth. But the voice on the phone was that of a family friend, telling me that my father had died overnight of an undiagnosed heart condition. In the moment I couldn’t even understand what was happening, saying over and over, “but I talked to him last night.” Soon I was sitting at home, dazed, on a string of tearful calls with family and friends.I often read words like “lifted” or “buoyed” to describe the stabilizing support of a network of loved ones. In my case this network was tethering me to reality over the next few weeks, preventing me from spinning off the Earth’s surface in a storm of sorrow and anxiety. The trauma also took a strange physical form and convinced me that I was suffering from a cardiac condition of my own. I had a panic attack during which I went to urgent care convinced my own heart was about to give way. Night after night these physical symptoms prevented me from sleeping.Graced by many loving connections with my siblings, my boyfriend, and close friends, I was actually weathering the process as well as one can. My PI gave me a firm directive to take as much time off as I needed. These were two key elements early in my healing process: a supportive network and an understanding advisor. The third was getting professional help, which I soon realized I needed. Even if I felt OK one day, I didn’t trust that I’d be OK the next. My grief formed too thick and too broad a landscape for me to navigate without help.Deciding to seek mental health resources and realizing that one needs them are often the hardest parts. Connecting with those resources once the decision has been made should be as simple as possible. I called a mental health number, and a triage counselor noted my therapy needs and verified my insurance. She asked what times and locations I preferred and then searched for an open appointment with a therapist who accepted my insurance. She also informed me that my coverage allowed 12 sessions with no copay, which was a pleasant surprise. The therapist who agreed to see me had very few openings, in part because this all happened in December—the holidays are especially busy for therapists. I was aiming for a time after normal working hours, or in the morning before I would head to lab, but none of those times were available. I didn’t like interrupting my workday to trot off to therapy. Taking a long break once a week meant I couldn’t run experiments or mentor my student during that time. But I made the sacrifice because my highest priority was getting the help I needed. There was no shortcut. Prioritizing mental health over lab work is tough for researchers, and I would never have accepted that kind of weekly disruption before my dad’s passing. But as a wonderful mentor of mine used to say, “You are the most valuable reagent in the lab.” She wasn’t describing mental health at the time, but the phrase now provided a guiding principle for my recovery. My first few sessions were on Tuesdays at 2:00 pm.The afternoon break turned out to be less disruptive than I had feared, because I had recently come back to the lab and was working short days. Had she asked, I would have told my PI where I was on Tuesday afternoons, but she wasn’t normally abreast of my daily schedule, so I didn’t seek her approval beforehand. Coordinating experiments with lab members thankfully wasn’t an issue because my work was largely independent; I simply let lab members know that I’d would be out of the lab for a bit on those days.The weeks went by, and the benefits of therapy accrued, helping me in large and small ways as I grieved. In mid-March of 2020, my therapist followed public health guidelines and asked all her clients to transition to remote sessions. While this was easy and sensible, it was still a little disappointing. Therapists are professional empaths, among many other things, and doing away with the physical presence and exchange with her was a blow. Yet therapy via video felt less odd simply because most of my social interactions were now virtual. Thankfully I didn’t have to move out of state for the lockdown (as did many students living in campus housing), which meant I could stay with the same therapist without any insurance complications.A few weeks into lockdown, I asked my therapist whether we had reached the limit of my 12 sessions without a copay. She replied with the good news that my insurance provider had waived all copays for mental health costs due to the pandemic. By that time therapy had generated a platform and an outlet to explore areas of my grief beyond the trauma of my father’s passing. Without needing to weigh the costs and benefits of this resource, I saw my therapist for another 4 months. I slowly took stock of my upbringing in an unconventional family and the loss of my mother when I was 25 and waded through a series of difficult decisions regarding my father’s estate. My father’s death changed me at a depth that is untouched by any amount of therapy or treatment. I’m not “healed”: I feel aged, more brittle, and a little ground down compared with who I had been. But therapy guided me through the worst of my grief, past the acute trauma to help me grasp what I was going through.Since the pandemic began, the number of people reporting increased stress or mental health issues has steadily increased (information on the impact of COVID-19 measures on mental health: https://www.apa.org/workforce/publications/depression-anxiety-coronavirus.pdf) (also see Mental health resources for trainees). I am fortunate to have affordable health insurance and the support from my lab and my department. The ease of finding my institution’s phone number for mental health resources was itself an important benefit. I share these pieces of my story with humility and understanding that not everyone enjoys the privileges that I do and the knowledge that everyone weathers life’s tragedies in their own way. It is not lost on me that some benefits stemmed from a policy change made by a private insurance provider. The provider made the right decision to waive copays, freeing me from having to choose between cost and my mental health needs. Yet had I been a student who had to move out of state due to COVID-19, access to mental health resources might have been disrupted or cut off. The need for reduced out-of-pocket costs for healthcare is known and needs no repetition, but the benefits of telehealth should be a low-cost component of health plans offered to students and staff (information on telehealth recommendations: https://www.apaservices.org/advocacy/news/congress-patient-telehealth?_ga=2.231013471.1538013741.1619359426-1228006513.1619359425 and http://www.apaservices.org/practice/advocacy/state/leadership/telebehavioral-health-policies.pdf?_ga=2.3385904.1067518037.1620039082-1228006513.1619359425.I’m not a cloud of emotions attached to a pair of good pipetting hands, I’m a human who is choosing to spend my time doing research. This observation is easy to repeat, by trainees as much as by faculty and administrators, but much harder to act upon in the midst of conflicting priorities. Consider my story a success: Because I could access the resources I needed, I was able to prioritize my mental health in the midst of my ambitious research program even during the lockdown.MEET THE AUTHORI have been a postdoc in Stefani Spranger’s lab at MIT for 4 years.

Mitochondrial alterations have been documented for many years in the brains of Parkinson’s disease (PD), a disorder that is characterized by the selective loss of dopamine neurons. Recent studies have demonstrated that Parkinson’s disease-associated proteins are either present in mitochondria or translocated into mitochondria in response to stress, further reinforcing the importance of the mitochondrial function in the pathogenesis of Parkinson’s disease. Exposure to environmental chemicals such as pesticides and heavy metals has been suggested as risk factors in the development of Parkinson’s disease. It has been reported that a number of environmental agents including tobacco smoke and perfluorinated compounds, pesticides, as well as metals (Mn2+ and Pb2+) modulate mitochondrial function. However the exact mechanism of mitochondrial alteration has not been defined in the context of the development and progression of Parkinson’s disease. The complexity of the mammalian system has made it difficult to dissect the molecular components involved in the pathogenesis of Parkinson’s disease. In the present study we used the nematode Caenorhabditis elegans (C. elegans) model of neuron degeneration and investigated the effect of environmental chemicals on mitochondrial biogenesis and mitochondrial gene regulation. Chronic exposure to low concentration (2 or 4 μM) of pesticide rotenone, resulted in significant loss of dopamine neuron in C. elegans, a classic feature of Parkinson’s disease. We then determined if the rotenone-induced neuron degeneration is accompanied by a change in mitochondria biogenesis. Analysis of mitochondrial genomic replication by quantitative PCR showed a dramatic decrease in mitochondrial DNA (mtDNA) copies of rotenone-treated C. elegans compared to control. This decreased mitochondrial biogenesis occurred prior to the development of loss of dopamine neurons, and was persistent. The inhibition of mtDNA replication was also found in C. elegans exposed to another neuron toxicant Mn2+ at the concentration 50 or 100 mM. We further examined the mitochondrial gene expression and found significant lower level of mitochondrial complex IV subunits COI and COII in C. elegans exposed to rotenone. These results demonstrate that environmental chemicals cause persistent suppression of mitochondrial biogenesis and mitochondrial gene expression, and suggest a critical role of modifying mitochondrial biogenesis in toxicants-induced neuron degeneration in C. elegans model.  相似文献

I am incredibly honored to receive the 2021 WICB Junior Award for Excellence in Research in WICB’s golden jubilee year. In this essay, I traverse my scientific journey starting with my PhD, highlighting the highs and the lows and how these intersect with luck, privilege, and bias.

V. AnanthanarayananMy pursuit for a PhD started with a hiccup—I had applied to several places in the United States, but barely got any offers due to the economic upheaval that happened that year (2008). I had to forgo any dreams of a PhD in the United States and remained in Bangalore, India to complete a project I had started with William (Bill) Thies at Microsoft Research India on a programming language for expressing biology protocols. Applying to U.S. schools was an expensive task, one which I was unwilling to put my family through again. So, a year later, when I recommenced my search for a PhD position, I set my sights on Europe. I had heard about the PhD program at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG ) at Dresden from a friend who had just joined the institute for her PhD. Fortunately, I received an interview call from MPI-CBG. At the end of a crucial interview week at Dresden, I “matched” with Iva Tolic´’s (now Institut Ruđer Boškovic´, Croatia) lab for my PhD. At the start of my PhD, I knew next to nothing about the cytoskeleton, motor proteins, or microscopy, but I found Iva and my lab members to be some of the warmest and most welcoming people. I made friends for life and graduated with a PhD in Biophysics, with a thesis focused on understanding the regulation of the motor protein cytoplasmic dynein. I was lucky to have been able to get a position at MPI-CBG and join Iva’s lab—of the other three places in Europe I had applied to for a PhD, only one other institute invited me for an interview, which also proved to be unsuccessful.On completing my PhD in 2014, I didn’t quite know what I wanted to do. Due to personal reasons, I had to return to India and was open to options in both industry and academia. But with my training in motor protein and cytoskeleton research, I had some ideas for exploring scientific questions related to dynein activation. However, most labs I approached for a postdoctoral position were not open to a project that was outside the realm of their research focus. Nonetheless, Iva, Nenad Pavin (University of Zagreb), and Jonathon (Joe) Howard (Yale University), who were members of my thesis advisory committee, gave me the courage to continue in academia. In my naïveté, I went ahead and applied for the INSPIRE Faculty Fellowship, which is targeted at fresh PhDs and junior postdoctoral fellows to establish their own independent group at an Indian institute. To my surprise, I ended up getting the fellowship. The next issue was finding a host institute that was preferably in Bangalore, where my partner was based. I applied at a few different places, but only after I attended IndiaBioscience’s Young Investigator Meeting in 2014 did I get the chance to meet representatives of potential host institutes, including the Indian Institute of Science (IISc). After a couple of research seminars at IISc, my application was assessed and I was offered the position of INSPIRE Faculty Fellow at the newly formed Centre for BioSystems Science and Engineering, IISc.While I did not have any additional start-up funding, I was given the infrastructure and the independence to pursue my research program. It was slow and frustrating at the start, not unlike most starting labs. I always wondered if it might have been easier if I had had a regular postdoctoral stint. During this time, I also started recognizing how hard it was to be a woman in Indian academia. As a woman principal investigator, one’s authority, expertise, and ability are constantly called into question. Justifying your presence in academia on a daily basis is an exhausting task. I had a great mentor in Sandhya Visweswariah (IISc) who helped me navigate the system. I also had an extremely supportive partner, who kept me going through some of the worst times. Eventually, my lab and I landed on our feet (more about this in “My INSPIRE’d Journey”). Our research has been recognized with grants and awards, but one of the most rewarding parts of the job is seeing other lab members discovering the joy of science (I wrote about my approach to mentorship recently [https://www.nature.com/articles/s41580-020-0256-6]).Three years into the faculty fellowship, I was able to transition to an Assistant Professor position in the same institute. However, this did not change my experience as a young woman in Indian science, and the implicit and explicit biases continued. In 2020, I accepted a fantastic opportunity to further my lab’s science as an EMBL Australia Group Leader at the Single Molecule Science Node at UNSW Sydney and made the move during a pandemic. My lab’s research focus is in understanding how stochastic and rare events pertaining to cytoskeleton and motor proteins give rise to complexity in intracellular organization. With this theme as the essence of our research, we ask specific questions about motor protein regulation to effect differential cellular trafficking, mitochondria-microtubule interactions, and their role in mitochondrial dynamics, and we aim to determine barcodes of global organelle positioning in health and disease.I have the privilege of being able-bodied, born in an upper middle-class family to college-educated parents who were extremely supportive of my choices. I have also inordinately benefitted from the fact that I was born to an Indian ‘upper caste’ family. I therefore had an undue head start in life. These were circumstances beyond my control and yet played a huge role in how my story turned out. I was embarrassingly ignorant of the rampant misogyny in academia until I had to contend with explicit and implicit gender-based biases myself when I started my independent research group in India. Women make up ∼40% of science PhDs awarded in India but represent only ∼13% of Indian academia (biaswatchindia.com), highlighting the stark gender biases at play in creating a leaky pipeline. While I tried my best to voice my discontent and affect changes to create an equitable environment within my department and institute, it was slow work. In 2020, when the pandemic hit and all conferences and meetings went virtual, conference posters advertised on social media made it immediately apparent just how much women were underrepresented in Indian STEM conferences. So, I teamed up with Shruti Muralidhar (now a scientist at Deep Genomics, Canada) to found BiasWatchIndia, an initiative to document women representation and combat gender-biased panels in Indian STEM conferences.BiasWatchIndia has been in existence for a little over a year now—we have achieved several milestones, but there’s still so much to do. “Manels” (conferences that feature only men) are still as rampant as they were when we first started—40% of all Indian STEM conferences are manels. And while we have just about started to tackle the underrepresentation of women in Indian STEM, we are conscious of the intersectionality of bias with gender, caste, ableism, and socioeconomic background and aim to understand how best we can advocate for all minorities.People who are in power in academia and who oppose equity, diversity, and inclusion initiatives and instead preach merit and equality as the gold standard need to introspect, because when options and opportunities are offered without consideration to the millennia of oppression based on gender, race, and background, it is not promoting equality but upholding values that will continue to oppress underrepresented groups. Still, I am optimistic and hope to see real changes that will result in equity in academia in my lifetime.  相似文献

The role of mitochondrial complex I in aging has been studied in both C. elegans and Drosophila, where RNAi knock down of specific complex I subunits has been shown to extend lifespan. More recently, studies in Drosophila have shown that an increase in mitochondrial activity, including complex I-like activity, can also slow aging. In this review, we discuss this apparent paradox. Improved maintenance of mitochondrial activity, mitochondrial homeostasis, may be responsible for lifespan extension in both cases. Decreased electron transport chain activity caused by reducing complex I subunit expression prompts an increase in stress response signaling that leads to enhanced mitochondrial homeostasis during aging. Increased complex I activity, as well as mitochondrial biogenesis, is expected to both directly counteract the decline in mitochondrial health that occurs during aging and may also increase cellular NAD+ levels, which have been linked to mitochondrial homeostatic mechanisms through activation of sirtuins. We suggest that manipulations that increase or decrease complex I activity both converge on improved mitochondrial homeostasis during aging, resulting in prolonged lifespan.  相似文献

Academia has fostered an unhealthy relationship with alcohol that has an undeniable impact on the health and behaviour of students and staff. Subject Categories: S&S: History & Philosophy of Science, Chemical Biology, S&S: Ethics

University life has a lot to offer. And, for better or worse, much of it goes hand in hand with a bottle. Believe it or not, I was a bit of teetotaler in my undergraduate days but quickly made up for it in graduate school, where each celebration included inebriation. Indeed, my initial tour of the laboratory I eventually worked in included a refreshing visit to the grad club. Orientation week ended with a marathon beer blitz at a nightclub. The semester’s first invited seminar speaker was welcomed with the sounds of loose change, ice buckets and the clickity‐clack of organic microbrews being opened. Our inaugural genome evolution journal club was such a success that we vowed to spill even more red wine onto our notebooks the following week. In hindsight, I should have realized at this early stage in my studies that I was fostering an unhealthy and unsustainable relationship between biology and booze. Unfortunately, my post‐graduate education in alcohol didn’t stop there.Like many keen students, I arrived at my first scientific conference with a belly full of nerves and a fistful of drink tickets, which I quickly put to good use at the poster session. The successful completion of my PhD proposal assessment was met with pats on the back as I was swiftly marched off to a local pub with no chance of escape. My first peer‐reviewed paper literally arrived with a pop as Champagne was generously poured into plastic cups for the entire laboratory group. My failures, too, were greeted with a liberal dose of ethanol. “Sorry you came up short on that scholarship application, Smitty. It’s nothing a little weapons‐grade Chianti won’t cure.” “That experiment failed again! Come on, let me buy you a lunchtime martini to make up for it.” Soon I learnt that every academic event, achievement or ailment, no matter how big or small, could be appropriately paired with beer, wine or spirit. Missing from the menu were two crucial ingredients for any burgeoning researcher: moderation and mindfulness.But it was the older vintages that really inspired me – the legendary drinking escapades of my scientific mentors, advisors and idols. The tale of professor so‐and‐so who at that epic meeting in 1993 polished off an entire magnum of rosé at dinner and then went on to deliver among the greatest keynote lectures on record at 9 am the following morning. That celebrated chaired researcher who kept the single malt next to the pipette tips for quick and easy access. The grizzled evolutionary ecologist who never went into the field without half a dozen cans of high‐end smoked oysters and two hip flaks, which didn’t contain water. And so, when I was told by someone in the know of how the most famous geneticist on campus wrote that monumental Nature paper (the one I’d read ten times!) while locked in his office for twelve hours with a six‐pack, I bought into the romance hook, line and sinker. The result: I’ve been nursing a recurring headache for nearly two decades and I’m still waiting on that Nature paper. Most importantly, I now realize the various dangers of romanticizing the bottle, especially for individuals in mentorship positions.Like my idols before me, I’ve accrued a cask full of well‐oaked academic drinking stories, except that they haven’t aged well. There is that heroic evening of intense scotch‐fueled scientific discussion, which led to me forfeiting two front teeth to the concrete sidewalk (my mother still thinks it was a squash accident). Or that time I commemorated the end of a great conference in Barcelona by throwing up on the front window of a café while the most prominent minds in my field sipped aperitifs inside (thank god this was before Twitter). Even more romantic: me buying a bottle of Cotes de Nuits Burgundy at Calgary airport on route to a job interview, discreetly opening the bottle in‐flight because economy class wine sucks, and then being met by airport security upon landing. Let’s just say I didn’t get the job. To some, these anecdotes might seem light‐hearted or silly, but they are actually rather sad and underscore the seriousness of substance abuse. Many readers will have their own complicated experiences with alcohol in academia and, I believe, will agree that it is high time we asked ourselves: are we training our graduate students to be great thinkers or great drinkers? Moreover, this question does not address the equally if not more serious issue of excessive drinking among undergraduate students.As I sit at my desk writing this, I think to myself: is it normal that within a two‐minute walk of my university office there are three different places on campus that I can have a beer before lunch, not including the minifridge behind my desk? Is it normal that in my department the first thing we do after a student defends their thesis is go to the grad club where they can have any alcoholic drink of their choosing for free from the goblet of knowledge, which is kept on a pedestal behind the bar? Is it normal that before the COVID pandemic when I was visiting a prominent university for an invited talk, one of the professors I met with offered me a glass of expensive Japanese gin at 11 am in the morning? (And, yes, I accepted the drink.)Of course, if you don’t want to drink you can just say no. But we are learning more and more how institutional cultures – “the deeply embedded patterns of organisational behaviour and the shared values, assumptions, beliefs or ideologies that members have about their organisation or its work” (Peterson & Spencer, 1991) – can have powerful effects on behaviour. Excessive alcohol consumption is undeniably an aspect of collegial culture, one that is having major impacts on the health and behaviour of students and staff, and one that I’ve been an active participant in for far too long. I’ll be turning forty in a few months and I have to face the fact that I’ve already drunk enough alcohol for two lifetimes, and not one drop of it has made me a better scientist, teacher or mentor. The question remains: how much more juice can I squeeze into this forty‐year‐old pickled lemon? Well, cheers to that.  相似文献

We need more openness about age‐related infertility as it is a particular risk for many female scientists in academia who feel that they have to delay having children. Subject Categories: S&S: Careers & Training, Genetics, Gene Therapy & Genetic Disease

Balancing motherhood and a career in academic research is a formidable challenge, and there is substantial literature available on the many difficulties that scientists and mothers face (Kamerlin, 2016). Unsurprisingly, these challenges are very off‐putting for many female scientists, causing us to keep delaying motherhood while pursuing our hypercompetitive academic careers with arguments “I’ll wait until I have a faculty position”, “I’ll wait until I have tenure”, and “I’ll wait until I’m a full professor”. The problem is that we frequently end up postponing getting children based on this logic until the choice is no longer ours: Fertility unfortunately does decline rapidly over the age of 35, notwithstanding other potential causes of infertility.This column is therefore not about the challenges of motherhood itself, but rather another situation frequently faced by women in academia, and one that is still not discussed openly: What if you want to have children and cannot, either because biology is not on your side, or because you waited too long, or both? My inspiration for writing this article is a combination of my own experiences battling infertility in my path to motherhood, and an excellent piece by Dr. Arghavan Salles for Time Magazine, outlining the difficulties she faced having spent her most fertile years training to be a surgeon, just to find out that it might be too late for motherhood when she came out the other side of her training (Salles, 2019). Unfortunately, as academic work models remain unsupportive of parenthood, despite significant improvements, this is not a problem faced only by physicians, but also one faced by both myself and many other women I have spoken to.I want to start by sharing my own story, because it is a bit more unusual. I have a very rare (~ 1 in 125,000 in women (Laitinen et al, 2011)) congenital endocrine disorder, Kallmann syndrome (KS) (Boehm et al, 2015); as a result, my body is unable to produce its own sex hormones and I don’t have a natural cycle. It doesn’t take much background in science to realize that this has a major negative impact on my fertility—individuals with KS can typically only conceive with the help of fertility treatment. It took me a long time to get a correct diagnosis, but even before that, in my twenties, I was being told that it is extremely unlikely I will ever have biological children. I didn’t realize back then that KS in women is a very treatable form of infertility, and that fertility treatments are progressing forward in leaps and bounds. As I was also adamant that I didn’t even want to be a mother but rather focus on my career, this was not something that caused me too much consternation at the time.In parallel, like Dr. Salles, I spent my most fertile years chasing the academic career path and kept finding—in my mind—good reasons to postpone even trying for a child. There is really never a good time to have a baby in academia (I tell any of my junior colleagues who ask to not plan their families around “if only X…” because there will always be a new X). Like many, I naïvely believed that in vitro fertilization (IVF) would be the magic bullet that can solve all my fertility problems. I accordingly thought it safe to pursue first a faculty position, then tenure, then a full professorship, as I will have to have fertility treatment anyhow. In my late twenties, my doctors suggested that I consider fertility preservation, for example, through egg freezing. At the time, however, the technology was both extravagantly expensive and unreliable and I brushed it off as unnecessary: when the time comes, I would just do IVF. In reality, the IVF success rates for women in their mid‐to‐late 30s are typically only ~ 40% per egg retrieval, and this only gets worse with age, something many women are not aware of when planning parenthood and careers. It is also an extremely strenuous process both physically and emotionally, as one is exposed to massive doses of hormones, multiple daily injections, tremendous financial cost, and general worries about whether it will work or not.Then reality hit. What I believed would be an easy journey turned out to be extremely challenging, and took almost three years, seven rounds of treatment, and two late pregnancy losses. While the driving factor for my infertility remained my endocrine disorder, my age played an increasing role in problems responding to treatment, and it was very nearly too late for me, despite being younger than 40. Despite these challenges, we are among the lucky ones and there are many others who are not.I am generally a very open person, and as I started the IVF process, I talked freely about this with female colleagues. Because I was open about my own predicament, colleagues from across the world, who had never mentioned it to me before, opened up and told me their own children were conceived through IVF. However, many colleagues also shared stories of trying, and how they are for various—not infrequently age‐related—reasons unable to have children, even after fertility treatment. These experiences are so common in academia, much more than you could ever imagine, but because of the societal taboos that still surround infertility and pregnancy and infant loss, they are not discussed openly. This means that many academic women are unprepared for the challenges surrounding infertility, particularly with advanced age. In addition, the silence surrounding this issue means that women lose out on what would have otherwise been a natural support network when facing a challenging situation, which can make you feel tremendously alone.There is no right or wrong in family planning decisions, and having children young, delaying having children or deciding to not have children at all are all equally valid choices. However, we do need more openness about the challenges of infertility, and we need to bring this discussion out of the shadows. My goal with this essay is to contribute to breaking the silence, so that academics of both genders can make informed choices, whether about the timing of when to build a family or about exploring fertility preservation—which in itself is not a guaranteed insurance policy—as relevant to their personal choices. Ultimately, we need an academic system that is supportive of all forms of family choices, and one that creates an environment compatible with parenthood so that so many academics do not feel pressured to delay parenthood until it might be too late.  相似文献

An interview with Facundo D Batista, The EMBO Journal new Editor‐in‐Chief.

An interview with Facundo D. Batista, The EMBO Journal new Chief Editor. Facundo D. Batista has shaped our understanding of the molecular and cellular biology of B‐cell activation. In 2016, he relocated his lab to Massachusetts General Hospital/M.I.T./Harvard’s Ragon Institute to explore the translational potential of two decades of basic research in B‐cell biology. The interview was conducted by Thiago Carvalho. Thiago Carvalho (TC): What inspired you to pursue a career in science? Facundo D Batista (FDB): I was very inspired by my undergraduate course on molecular biology at the University of Buenos Aires. The course was given for the first time, and we were taught the basic techniques of handling DNA, producing insulin, and so forth. Two professors in the course, Daniel Goldstein and Alberto Kornblihtt, really primed us to open our horizons and encouraged training in centers of excellence abroad. I did not speak any English at all, and applying to graduate school in the United States and doing the GRE was impossible for me. I would not have passed. Then, an opportunity to go to Italy and get experience in institutes that could provide me with better training came up. If I recall correctly, we were the first generation of Argentinian biology graduates—myself, Pablo Pomposiello, and many others—that left Argentina looking for a PhD. In general, people would try for a postdoc.I applied to a PhD program in Italy. I went with an open ticket for a year. If I had not passed the ICGEB/SISSA (Trieste) examination, I had three thousand dollars to travel around, and then I would go back to Argentina. I had never been in Europe before. So, for me it was an experience. What happened was that I was very lucky to be admitted in probably the first generation of this new institution, the International Centre for Genetic Engineering and Biotechnology in Italy. In three years, I finished my PhD, and then, to be honest, as an Argentinian in Europe, I did not have many postdoctoral funding opportunities either. TC: How did you move from Trieste to Cambridge’s Laboratory of Molecular Biology? FDB: I found Michael Neuberger’s laboratory to be very appealing, and I wrote to Michael. He replied to me, in a letter that I still keep, that—if I was able to obtain a fellowship—he would take me in his laboratory. A wonderful thing about EMBO was that it would recognize the country where you did your PhD when considering postdoctoral fellowship applications, giving me access to this important funding support. 1 It was the very early days of diversity—the notion that people could be eligible for support based not only on their nationality, but also on their “scientific nationality”. It gave me a unique opportunity. TC: It was also an opportunity to meet another source of inspiration for you, César Milstein FDB: César was not well at the time, he had heart problems. But I met him, and I felt very close because Michael was working with César, and he worked next door. For me, walking in those corridors with César Milstein and several other Nobel Prize winners—you know, Aaron Klug and Max Perutz—it was a dream. I could not believe that you could have lunch with these wonderful people, and they would come and talk to you, not as Dr. Klug or Dr. Milstein, but they would be César, Aaron, and Max. That for me was totally mind‐changing, together with my relationship with Michael, whom I love. They completely changed my perspective on science. TC: What do you remember most about Michael Neuberger as a mentor? FDB: What was incredible about Michael was his clarity. You would present any biological problem to him, and he would crystallize in one sentence what the real question behind it was. He was amazing. Michael would enter into a state of thinking where he would stop looking at you and would start looking up at a wall and would start to concentrate for those 10, 20 minutes that you’d explain the problem. Then, he would come up with critical questions and he would be critical to the bones. I think that that is something that science has lost these days. I think that this notion of going deep into critically asking the right scientific questions has been lost as a tradition. It is something that I try to transmit to my postdocs and PhD students: Scientific criticism is not about personal or emotional evaluation. It is really about trying to nail down what the question is and how a project develops. I think that is what I remember most of Michael, his commitment to the people that worked with him and who surrounded him and that deep thinking and constant challenging about what is the next step. TC: In 2002, you started your laboratory at the London Research Institute FDB: I was at one stage considering staying at the LMB with my independent lab, and César and Michael were very supportive of that. But then came the opportunity to join the LRI—which at the time was still the ICRF. I was the last employee recruited (to the ICRF), and it was wonderful. The notion of changing environments again, changing colleagues. The LMB was not an immunology institute. It was a general research institute and the ICRF at that time was similar, with very little immunology. I have always valued the whole spectrum of biology from mathematical modeling to quantitative biology to biochemistry to technological inputs, to development, and so forth. TC: Your LRI laboratory revealed entirely new aspects of the molecular and cellular biology of B lymphocytes—one was the existence of organized membrane structures reminiscent of the immunological synapse first described in T cells that were crucial for activation. What are the implications of the immunological synapse for B‐cell function? FDB: It was a concept that was resisted by the B‐cell field. The notion at the time was that B cells would get activated by soluble antigens. But if you think about it, that does not make any sense. You will never reach a physiological concentration of a ligand that will allow you to engage a receptor in vivo at a low affinity. So in order to reach that concentration, you need to aggregate antigen on the surface of other cells first. And that makes the whole process much more efficient. It not only localizes the process into lymph nodes or spleens, but it also allows focusing the response into what the arrangement of a membrane is. I was not the first—the notion that antigens are on follicular dendritic cells was well‐established by early experiments. But I think our work transformed the field. A lot of laboratories have incorporated the notion that stimulating cells at the level of membranes changes the way that receptors perceive signals. This does not apply only to the B‐cell receptor, it applies to chemokines too, many of them are also coating the surface of other cells and that helps guide the signals that cells receive.I think that it is an important concept that is likely to be applicable to vaccines. There are several papers now showing that helping to aggregate antigens on the surface of macrophages or dendritic cells makes antigens more potent by driving them more efficiently into where they are used in follicles and lymph nodes. TC: What prompted your pivot to translational research? FDB: I had learned a lot about basic principles of B‐cell biology and antibody responses, but on model antigens. I felt at the time that translating that into humans and trying to understand how vaccines could be improved was an important step. I always like to recognize mentors or people who influenced me and one person who really influenced me in this thinking was Dennis Burton at Scripps. He was very early to incorporate into his HIV vaccine and antibody research people like me or Michelle Nussenzweig that were coming from basic B‐cell immunology to try to help to think about how vaccines can be improved. I decided to take a risk. I left a tenured, core‐funded position at the best institution in Europe to lead the Ragon Institute with Bruce Walker—I am the Associate Director and he is the Director—and brought my years of expertise at the ICGEB, LMB, LRI, and CRICK to a unique environment that is based on translational research. There is the incredible ecosystem of Harvard, MIT, and MGH, and the notion is to incorporate technologies and to incorporate immunology to tackle incredible challenges, like COVID‐19 is today. TC: Are there any major initiatives that you plan to focus on at The EMBO Journal? FDB: One of the things that I would really like to do is to involve the younger generations in the journal. I think that we have an opportunity for direct “translation”. I mean, EMBO has EMBO postdoctoral fellowships and EMBO young investigators, involving early career European scientists, but also scientists across the globe. We are discussing initiatives like, for example, inviting postdocs from different laboratories to present at the editorial meetings. The EMBO Journal has an open‐door policy in terms of people wanting to participate in the editorial meetings.I think that we have amazing scientists around the world that can really bring new views as to where the journal should be going. I feel strongly about that and about keeping a real sense of diversity in the journal, in terms of fields, in terms of gender, in terms of race, in getting people involved from Brazil, getting people involved from China, getting people involved from Japan, from across the globe. EMBO is no longer a European journal. EMBO is a journal whose office faces Europe, but it has a global outlook. TC: Early in their career, many researchers do not feel comfortable engaging with editors FDB: I sent one of my first papers as an independent P.I. to EMBO. That paper was editorially rejected. I replied to that rejection, saying that EMBO should stop publishing just biochemistry, and that they needed to appreciate the importance of quantitative cell biology. The paper was ultimately sent to review and accepted. What was also very positive was that a later review of the scope of The EMBO Journal came to a similar conclusion. That resulted in my appointment to the editorial advisory board of The EMBO Journal (I was not an EMBO member at the time). The positive message is that the journal very much welcomed receiving feedback. That was what made me like the journal. I felt that the journal was ready to listen, to change.This is not my journal. It is the community’s journal. I am just playing a role, putting in some time and effort. There are a lot of things that I do not see and other young people could see, and I am looking for inspiration there, to listen and translate those things into good policies for the journal. I think that this is important and I think that this is at the basis of what I want to be as a chief editor.  相似文献

I am just starting my career as a cancer biologist, but I have always been a Black man in America. This means that I have always inhabited a world that generally disregarded my existence in some form or another. It is June 17th, 2020 and protests have been happening for weeks since the killing of George Floyd in Minneapolis. The current state of America may be uneasy for some, but for many Americans, the looming threat of exclusion and violence has been an unwelcome companion since birth. This letter is not about a single person, but the Black academic’s experience of race inside and outside of the academy during a time of social upheaval. I have trained in a variety of institutions, big and small, and all the while acutely aware of the impact of my Blackness on my science. The intent of the following is to provoke the reader to reflect on how we as a nation can move toward radically positive change and not incremental adjustments to the status quo. The views expressed are my own and are the result of years of personal experience observing the anti-Black standard in America.

About the AuthorI am currently a cancer biologist at the University of Minnesota Medical School. My lab works to eliminate cancer health disparities in African Heritage communities and investigates the roles of lipids in modifying the immune response in tumors. This is what I do, but not all of who I am. I am also the eldest child of a mother, who managed to convince me that she had eyes in the back of her head (thank you, Mom; it kept me honest). I am a big brother, a husband, and a father. I also consider myself a fortunate Black man in America. I grew up in places where many of my friends did not live to adulthood. If they managed to survive past adolescence, it was usually their dreams that died prematurely. I was lucky to have survived and to continue chasing my dream of becoming a scientist. I never considered myself the fastest, strongest, or even smartest kid growing up, but I was the most determined. Determined, despite the lack of access to role models in science that looked like me or shared my life experience. Now my mission is to increase the number of dreams achieved and impact as many young minds as my time on this planet permits.As a Black scientist, I sometimes have to remind myself that I have never been immune to racism. Because as you spend thousands of hours delving into the microscopic world, the macroworld starts to fade into the background like white noise. And if you get good at it, you almost forget about the strange looks, the excessive questioning, or even the obligatory “tailing” in stores, on campus, or at home. But it is strange to realize how much you have grown accustomed to discrimination and the fact that you unconsciously prepare for it daily, before it ever shows its ugly head, like a prize fighter training months before a fight.This past month, amid the Coronavirus Disease 2019 (COVID-19) pandemic, the rest of the world has decided to say police are bad, and oh, by the way, Black lives matter too—as if the oppression of Black bodies was new, or as though the recent string of names added to the ever-growing list of innocent Black Americans killed by authorities is an atypical occurrence. Well sadly it is not, and it never has been in this country or any other place with colonial origins. That is the truth, and there is no other way to state it. America is a country built on and driven by racist ideology.So, as a Black American in an “essential” worker role (I am now working on COVID–19-related research), I have physically been at work daily during the pandemic, as the spirit of solidarity sweeps the globe. As much as I want to say this is progress, I find myself asking “why now, and not then?” Why didn’t this happen when Trayvon Martin was murdered; why didn’t this happen when Rodney King was beaten (Alvarez and Buckley, 2013; Mullen and Skitka, 2006)? Is it a sign of the end times, or is it just that racism/White supremacy has finally run its course?I have a theory about why we are now seeing a mass movement against discrimination and police brutality (a.k.a. state-sanctioned murder). My theory states that had it not been for COVID-19 and the nationwide shutdown of normal life, none of this protesting would even be feasible. Why do you ask? The simple answer is that some people with the financial means can normally find ways to distract themselves with various activities, some noble and some … not so much, whereas other folks are less able to disconnect from the drudgery of hand-to-mouth living. Leave it to a global health crisis to reprioritize everyone’s entire life in one fell swoop. Suddenly, people who had vacation plans are stuck at home, whereas people who were just making ends meet are now unable to make those ends meet anymore. The haves and the have-nots are now both in an altered reality. Does this make them equal now? No, but it does allow people to see who their real friends, allies, and enemies are. I suspect that it’s the pulling back of the curtain that has made many people ready to fight, not to mention it is also very likely that many folks, after experiencing weeks of cabin fever, just needed some way to let off all that pent-up energy.Before COVID-19 became a full-time concern, tensions in the United States were already high as the recent killings of unarmed Black Americans (Breonna Taylor and Ahmaud Arbery) had gone viral and cries for justice echoed from coast to coast (Lovan, 2020). Once the reality of the pandemic set in and shelter-in-place orders were issued nationally, the situation became a powder keg waiting for just the right moment. That moment happened in North Minneapolis on May 25, 2020. With the release of the video showing the killing of George Floyd, the entire country and much of the world had a reason to go on a “righteous rampage” that has seemed to get the results some thought impossible to achieve. It cannot be overstated how critical social media has been in displaying the oppression of Black Americans at the hands of authorities to the entire world.Now, several months into the protests, the possibility of a “new’’ new normal has people dreaming of singing Kumbaya in technicolor. Yet, as one of the few Black faculty on my campus, I still feel like people are watching me, but for a different reason now. As various reforms are broadcast across the university, the random wellness “check-ins” start creeping in, and the requests for feedback on “new initiatives’’ seem to be like a new flavor of spam in my inbox.Now, I do appreciate the fact that people are starting to notice the oppressive nature of not being White in today’s world (in particular being Black in America), but I have been doing this for a while now, and I am not sure if hashtagged initiatives are healthy for anyone. Plus, it’s kind of creepy watching all of these people jump on the social justice bandwagon, when they weren’t here 4 mo ago or 4 years ago. For many Black academics, it is not about being involved with something when it’s trending; it’s about being “about that life” when it is inconvenient as hell. Again, I do appreciate the fact that more people are willing to fight oppression, racism, and White supremacy (even if only digitally), but you will have to forgive me if I do not trust you just yet. I mean, you are just checking in during what could be the last leg of a marathon, and we’ve been running this whole damn time!Here is a short answer to every wellness check-in email that many of the Black academics I know have received in the last 2 mo: “we were never okay in the first place, but thanks for FINALLY asking!” We don’t need any more bias training, hashtags, or email check-ins. It was a nice start, but it too has become a part of the status quo. The work now and always has been the eradication of underrepresentation, hurtful socialization, and ridiculously skewed power dynamics, not just the awareness of the fact. I don’t have all the answers, but if real change is desired, I think we can first start by teaching history accurately to EVERYONE, no more whitewashing the reality of America’s story and ignoring the contributions of Black academics (and Black Americans in general). Second, stop being silent when you see or hear racism at work or home. If you do nothing when racism shows up, you ARE a racist! Third, the privileged class must relinquish their “privilege” once and for all. That means the powers that were inherited based on historical (and present day) theft and oppression have to dissipate, with the ultimate goal of power sharing. The country club atmosphere of academia and the “fit culture” must erode in favor of true meritocracy. The best person for the job and not “the person who won’t make me uncomfortable by making me see my own deeply held prejudices and fears.”Honestly, Black academics SHOULD not be charged with the task of fixing broken systems, along with protecting themselves and mentees, while working toward tenure. But if we (Black academics) are not driving the car, progress will likely go the wrong way again (getting rid of Uncle Ben and Aunt Jemima does not correct the underlying pathology). Paulo Freire’s Pedagogy of the Oppressed speaks to this in saying, “the violence of the oppressors prevents the oppressed from being fully human, the response of the latter to this violence is grounded in the desire to pursue the right to be human … the oppressed, fighting to be human, take away the oppressors’ power to dominate and suppress, they restore to the oppressors the humanity they had lost in the exercise of oppression.” (Friere, 1972, p. 56). This means that if we (Black academics) want to be treated as humans and as scholars, we must show you what that humanity looks like FIRST. Now the question is, are you willing to learn or are you going to co-opt this moment, this movement to make it into something that fits your preconceived notion of the acceptable levels of Blackness in the academy?  相似文献

If this was not happening in the midst of the COVID-19 pandemic, I imagine that I would be speaking these words instead of writing them on my laptop. Even so, I am so jazzed for this opportunity! No word or phrase describes what I am feeling in this moment in receiving the 2021 American Society for Cell Biology Prize for Excellence in Inclusivity. It is certainly an honor to be recognized in this way. I am grateful to the Howard Hughes Medical Institute for awarding me additional resources to keep on keeping on. My approach to finding the connection between people and their science certainly could use the monetary support. Resources open doors. At the same time that I am grateful for the attention, I am not exactly sure what to do with the spotlight. Importantly, there are a host of other folks out there also doing amazing things who have never been recognized. Let’s work to ensure that their contributions are supported, appreciated, and recognized. Instead of focusing the spotlight on me, I would rather redirect it to recognize my foundational influences. I also hope to encourage the need for institutional approaches beyond celebrating individual accomplishment.

O. A. Quintero‐CarmonaJo Rae Wright was my graduate advisor and the model for how I have tried to work with my students and colleagues to support their opportunities while also “doing science.” I wanted to start graduate school as soon as I could after graduating college, so after letting the Cell and Molecular Biology Program at Duke University know that I was accepting their offer, I started thumbing through their program booklet looking for labs with interesting research projects (a web presence wasn’t even really a thing for departments in 1996). I worked alphabetically and contacted a handful of labs one at a time to see whether anyone was willing to take on an early-rotation student. It was an unusual request for the way that the program had operated previously, and Jo Rae was the only person to agree to it. I don’t remember exactly, but she said something like, “We accepted you into the program, so I would be happy to host your first rotation.” The sense that I got was that, within the limits of her time and resources, she was willing to become my mentor because I needed one. She trusted the admissions process, so why not bring an eager student into the lab. I spent the summer settling in to the life of a graduate student—sort of.At first, I was bad at graduate school. I am curious about all sorts of things, which means I am also easily pulled in too many directions. In that first year of school I spent way too much time simply visiting other students in my cohort to see what it was that they were up to each day. I cannot imagine how distracting I must have been to them and probably extremely irritating to their PIs as well. If you were in Cell Biology at Duke in 1996–97, I am sincerely grateful that you tolerated my shenanigans. Where others might have taken me to task, Jo Rae looked for opportunities to redirect my energies more productively. She and another professor, Dan Kiehart, guided me toward participating in the Physiology Course at the Marine Biological Laboratory, where I learned what I needed to do to be a scientist in a way that would not have been possible otherwise. While there, I saw PIs working with students chasing the joy of discovery, and it felt like it was purely for the sake of a deeper understanding of biology and preparing the next generation of scientists to do the same. Resources gave us the liberty to focus on scientific discovery with minimal concern for where would be the highest profile place to publish. Although I acknowledge that the summer course environments may not be the most representative of the daily life of a scientist at a home institution, such an opportunity left a mark—I wanted to come as close as I could to emulating that environment when I got back to Duke and (eventually) when I had the chance to run a research group and teach students.Along the way, Jo Rae made sure to include me and my fellow lab mates in all aspects of the science. At national meetings she included us at every step, introducing us to her contemporaries and putting us in spaces where we would rub elbows with luminaries in the field. When we were in those environments, she made sure that I felt like a junior colleague. I cannot recall ever feeling like a “trainee.” Back home at Duke, I had opportunities to do everything that a scientist might do in addition to “sciencing.” Sure, I would write papers, contribute to grants, and be part of her review of papers. I was also encouraged to mentor undergraduates, teach, advocate for federal funding at the time of the National Institutes of Health (NIH) doubling, and plan events for Duke’s summer undergraduate research program, if I so chose. Similarly, when I expressed an interest in focusing on science with undergraduates, she was 100% on board with finding ways to combine my graduate school commitments with teaching and mentoring opportunities. Importantly, at a time when expressing interest in an “alternative career” was not always supported by faculty mentors, Jo Rae encouraged me to seek out only those potential postdoctoral mentors who would actively support my goals. Not only that, she went out of her way to find out what options I might have, which led to her learning about the NIH-funded Institutional Research and Academic Career Development Award postdoctoral programs in their first year of existence.In a sentence, because Jo Rae was 100% invested in including me in science by finding the framework that best suited my interests and potential, I grew into my success. This was a form of success that wasn’t decided by someone else; I had defined it for myself with Jo Rae serving as a true advisor in every sense of the word—she was in it for me. She helped to build the crucial foundations that helped me find the opportunities that matched my goals. As a result of her influence, I have also had the strength to make some critical, nontraditional choices along the way. Her mentorship style was tailored to each individual’s needs. She invested the time to figure out our strengths, and also learned which levers would motivate us to meet our potential. The members of her lab became successes because she helped all of us to both define success and achieve our own version of it. Such a personal approach is extremely powerful. Jo Rae passed away in 2012, and with her passing I lost the most important influence in my professional life. Duke University and the pulmonary physiology community lost an example for inclusive mentorship and a significant amount of capacity for such an approach. Since her passing, multiple awards have been established to honor Jo Rae’s legacy as an outstanding woman in science. I would argue that mentoring of junior colleagues may be a more significant legacy than her scientific output. Jo Rae is deserving of this award.Recognitions such as this one are an important way to amplify examples of what we often say we hope to achieve as a department, an institution, or a scientific society. However, if our focus is solely on the efforts of individuals, we are missing an opportunity. While I am humbled to be considered in the same league as the previous award recipients, we are each in our own way scrambling to do what we can while we can do it. When individuals have some positive outcomes, our institutions and organizations will celebrate what these folks have done as they have played some role in supporting these opportunities. Although what we do is worthwhile, it is really hard to do it successfully and sustainably without proper institutional support. We each face hinderances that can undermine the work that we want to take on. Burnout is a real outcome of doing the work that we care about and that our organizations publicly state is important. This is especially true in environments where that work is undervalued and underresourced. You do not have to do a very extensive internet search to identify where the institutions that have supported my work also have exclusionary legacies and current negative influences that continue to hinder their potential for broader, more meaningful progress. In many instances inclusion has yet to be baked into institutional culture in a way that impacts how organizations operate. Although I have had some institutional support to develop a career modeled on what I experienced under Jo Rae’s mentorship, the students and faculty at these institutions know that what gets headlines can often be an exceptional situation, rather than a typical everyday experience. Rather than showcasing the good work of individuals in their ranks, an organization should devote itself to furthering the idea that it is willing to make significant institutional investments in that good work. By building the internal infrastructure and capacity to support inclusion efforts, organizations would demonstrate that inclusion is an essential component of the institutional standard practice. The positive outcomes that this award is intended to highlight would then be a shared characteristic of the community. A shared vision paired with shared effort and resource-support might cut down on burnout of those currently carrying more than their share of the load.I imagine that the idea for these awards is to celebrate good work while also demonstrating to other individuals what is possible. With that in mind, if institutions worked at using the example of those in the vanguard as a way to build structures that value and support inclusive approaches, they would increase their own ability to serve their constituents. They may also influence other institutions to do the same. My graduate institution benefited from Jo Rae’s work while she was present and was beginning to institutionalize her view of inclusion in the last years of her life. As Dean of the Graduate School, the model for how she ran her lab informed her vision for graduate education campus-wide. She wanted to build a structure that would identify, recruit, and retain talent. She wanted to provide that talent with opportunities to become expert in how they wanted to contribute to the world. By ensuring that they had access to the relevant experiences and skills, she hoped to support them as they set themselves up for success as they defined it.I accept this award in honor of Jo Rae Wright, and on behalf of the students who have trusted me. All I have ever wanted was to be able to recreate for my undergraduates what Jo Rae had done for the people under her wing. I am building a career around that goal as part of a department keenly supportive of these efforts. My hope is that other individuals will develop their own approaches to inclusion because they find themselves in supportive institutional environments. More importantly, I would like to see organizations begin to truly prioritize inclusive approaches through funding and through policy. Institutions could make sufficient resources available to support inclusive efforts and allow creativity in how faculty mobilize those resources. Just as Jo Rae had the flexibility to adjust to our needs, institutional efforts will benefit when limited resource access is not a hindrance to inclusive excellence. Additionally, it will be critical to acknowledge the time and effort that such endeavors require in evaluating faculty contributions. It can no longer be the icing on the cake of a portfolio—developing inclusive capacity has to be recognized as an essential component of our work. Until these changes take root at the institutional level, this kind of work may shine brightly, but will continue to be stochastic and short-lived. All those efforts “will be lost in time, like tears in rain.” It is on all of us to prevent such a tragic ending.  相似文献

Although there is a consensus that mitochondrial function is somehow linked to the aging process, the exact role played by mitochondria in this process remains unresolved. The discovery that reduced activity of the mitochondrial enzyme CLK-1/MCLK1 (also known as COQ7) extends lifespan in both Caenorhabditis elegans and mice has provided a genetic model to test mitochondrial theories of aging. We have recently shown that the mitochondria of young, long-lived, Mclk1+/− mice are dysfunctional, exhibiting reduced energy metabolism and a substantial increase in oxidative stress. Here we demonstrate that this altered mitochondrial condition in young animals paradoxically results in an almost complete protection from the age-de pend ent loss of mitochondrial function as well as in a significant attenuation of the rate of development of oxidative biomarkers of aging. Moreover, we show that reduction in MCLK1 levels can also gradually prevent the deterioration of mitochondrial function and associated increase of global oxidative stress that is normally observed in Sod2+/− mutants. We hypothesize that the mitochondrial dysfunction observed in young Mclk1+/− mutants induces a physiological state that ultimately allows for their slow rate of aging. Thus, our study provides for a unique vertebrate model in which an initial alteration in a specific mitochondrial function is linked to long term beneficial effects on biomarkers of aging and, furthermore, provides for new evidence which indicates that mitochondrial oxidative stress is not causal to aging.Because it is well known that the aging process is characterized by declines in basal metabolic rate and in the general performance of energy-dependent processes, many aging studies have focused on mitochondria because of their central role in producing chemical energy (ATP) by oxidative phosphorylation (1). Among the various theories of aging that have been proposed, the mitochondrial oxidative stress theory of aging is the most widely acknowledged and studied (24). It is based on the observation that mitochondrial energy metabolism produces reactive oxygen species (ROS),2 that mitochondrial components are damaged by ROS, that mitochondrial function is progressively lost during aging, and that the progressive accumulation of global oxidative damage is strongly correlated with the aged phenotype. However, the crucial question of whether these facts mean that mitochondrial dysfunction and the related ROS production cause aging remains unproven (57). Furthermore, recent observations made in various species, including mammals, have begun to directly challenge this hypothesis, notably by relating oxidative stress to long (8) or increased (9) lifespans, by demonstrating that overexpression of the main antioxidant enzymes does not extend lifespan (10) as well as by showing that mitochondrial dysfunction could protect against age-related diseases (11).A direct and powerful approach to attempt to clarify this major question and to test the theory is to characterize the mitochondrial function of long-lived mutants (12). CLK-1/MCLK1 is an evolutionary conserved protein (13) and has been found to be located in the mitochondria of yeast (14), worms (15), and mice (16). The inactivation of the Caenorhabditis elegans gene clk-1 substantially increases lifespan (17). Moreover, the elimination of one functional allele of its murine orthologue also resulted in an extended longevity for Mclk1+/− mice in three distinct genetic backgrounds (18). These findings have provided for an evolutionarily conserved pathways of animal aging that is affected by the function of a mitochondrial protein (19, 20). In mitochondria CLK1/MCLK1 acts as an hydroxylase and is implicated in the biosynthesis of ubiquinone (coenzyme Q or UQ), a lipid-like molecule primarily known as an electron carrier in the mitochondrial respiratory chain and as a membrane antioxidant but which is also associated with an increasing number of different aspects of cellular metabolism (20, 21). Taken together, these observations indicate that the long-lived Mclk1+/− mouse is a model of choice for the understanding of the links between mitochondrial energy metabolism, oxidative stress, and the aging process in mammals.Previous analysis of Mclk1+/− mice, which show the expected reduction of MCLK1 protein levels (22), have revealed that their tissues as well as their mitochondria contain normal levels of UQ at 3 months of age (23). Yet the same study also revealed a host of phenotypes induced by Mclk1 heterozygosity (see below). Thus, it appears that MCLK1 has an additional function that is unrelated to UQ biosynthesis but responsible for the phenotypes observed in young Mclk1+/− mutants. This is consistent with several results from nematodes which also strongly suggest that CLK-1 has other functions (24, 25).In depth characterization of the phenotype of young Mclk1+/− mutants has revealed that the reduction of MCLK1 levels in these animals profoundly alters their mitochondrial function despite the fact that UQ production is unaffected (23). In fact, we have shown that Mclk1 heterozygosity induces a severe impairment of mitochondrial energy metabolism as revealed by a reduction in the rates of mitochondrial electron transport and oxygen consumption as well as in ATP synthesis and ATP levels in both the mitochondria and the whole cell. ATP levels in several organs were surprisingly strongly affected with, for example, a 50% reduction of overall cellular ATP levels in the livers of Mclk1+/− mutants (23). Moreover, we have found that the Mclk1+/− mice sustain high mitochondrial oxidative stress by a variety of measurements, including aconitase activity, protein carbonylation, and ROS production (23). Additionally, we have shown that this early mitochondrial dysfunction is associated with a reduction in some aspects of cytosolic oxidative damage and global oxidative stress that can be measured via recognized plasma biomarkers such as 8-isoprostanes and 8-hydroxy-2-deoxyguanosine (8-OHdG). Considering that the accumulation of global oxidative damage is known to be tightly linked to the aging process (26), this latter result suggests that the anti-aging effect triggered by low MCLK1 levels might already act at a young age.To further investigate the clk-1/Mclk1-dependent mechanism of aging as well as to try to elucidate the still unclear relation between mitochondrial dysfunction, oxidative stress, and aging, we have now carefully analyzed the evolution of the phenotype of Mclk1+/− mutants over time. We have also studied the effects of reduced MCLK1 levels on the phenotype of mice heterozygous for the mitochondrial superoxide dismutase (Sod2), which represent a well known model of mitochondrial oxidative stress (27). In addition of confirming the long lifespan phenotype of the Mclk1+/− mutants in a mixed background (129S6 x BALB/c), we also report here a study of mutants and controls on a completely isogenic background where we find that the condition of Mclk1+/− mutants unexpectedly results in protection against the age-dependent loss of mitochondrial function. Moreover, we found that the mutants are characterized by a significant attenuation of the age-associated increase in global oxidative stress normally observed in mammals. We also show that the Mclk1+/− condition can gradually reverse the deterioration of mitochondrial function and the associated increase of global oxidative stress that is normally observed in Sod2+/− mutants. Thus, this study provides for a unique vertebrate model in which reduced levels of a specific mitochondrial protein causes early mitochondrial dysfunction but has long term beneficial effects that slow down the rate of aging, as established with appropriate biomarkers, and can ultimately prolong lifespan in mice. Furthermore, in line with recent studies that have raised doubts about the validity of the mitochondrial oxidative stress theory of aging (4, 8, 10), our results, which relate to a recognized long-lived mice model, represent a novel and crucial indication that mitochondrial oxidative stress might not by itself be causal to aging.  相似文献

The murder of George Floyd sparked an awakening, long overdue, which reverberated throughout society. As science begins to acknowledge its role in perpetuating systematic racism, the voices of Black scientists, which have largely been absent, are now being called on. As we rightly begin to make space for diverse voices and perspectives in science, we all must think about what it is we are asking minoritized individuals to do.

It has been roughly 1 year since the murder of George Floyd, an unarmed Black man, who was killed over an alleged counterfeit 20 dollar bill in Minneapolis, Minnesota (Hill et al. 2020; Kaul, 2020; Levenson, 2021). In many ways, his murder was no different than the murders of thousands of other murders of Black people in this country (Thompson, 2020; Lett et al., 2021; Tate et al., 2021). However, what distinguishes George Floyd’s murder from many other high profile cases is that it was unambiguously captured on video (Alexander, 1994), an act of bravery by Darnella Frazier, a 17-year-old Black woman (Izadi, 2021), at a time when the world was mostly housebound by a raging global pandemic. As a result, his murder reverberated through society in a way that has not happened in my lifetime. While there have been other high profile cases of murders carried out by police (Treyvon Martin, Walter Scott, Breonna Taylor, and Philando Castile, among many others), these cases failed to fully sustain the attention of a national and international audience (Chan et al., 2020; Chughtai, 2021). The murder of George Floyd was fundamentally different, and for once, more than just Black people were paying attention. His murder sparked protests across the nation led by the Black Lives Matter (BLM) movement (Day, 2015; Taylor, 2016; Banks, 2018; Taylor, 2021), and the demands for change were so loud people could not help but hear.As a Black, gay man who is also a scientist, I was thrown into despair. All of my life I have thought if I just worked hard enough, if I am kind and unthreatening, if I play the game and keep my head down, maybe I can make it in academia. Maybe then I will be seen and accepted, not just by society, but by the scientific community. George Floyd’s murder reminded me, and many of my Black colleagues, that our degrees can’t protect us, that our privileged middle-class upbringing (if we had one) was not a shield. Our lives were not worth more than a counterfeit 20 dollar bill.Science, which has always been a product of society, was not impervious to these reverberations. By late June my inbox began to slowly fill with invitations to speak at several institutions for their seminar series, retreats, or special symposia. It felt as if the scientific community, for the first time, realized that there were Black scientists among them. In the throes of my own despair, and the feeling that I needed to be doing something for my community, I began to say “yes.” I was not going to participate in the nightly protests that occurred in my newly adopted hometown of Portland, Oregon. Aside from fearing I could be next to lose my life at the hands of the police (Edwards et al., 2019), these protests were happening in the backdrop of a global pandemic. I came to the conclusion that by accepting these invitations to speak, this could be my activism, my way of sparking change, increasing visibility, and being seen not only for my own sake but also for other Black scientists.Before I write anything else, I want to be clear: I am extremely thankful to all the institutions and organizations that invited me and gave me a platform. I am extremely proud of my students’ work and of the research we produce. I am sharing my experiences with the hope that they can be instructive to the greater scientific community, but if I am being frank, there is a bit of anger.I received over 15 invitations and gave an additional three or four interviews over the course of the year. Most of these came with the expectation that I would also talk about my work in Diversity, Equity, and Inclusion. But here’s the lowdown: prior to this year, I did not view myself as someone who did Diversity, Equity, and Inclusion work. I am co-chair of the LGBTQ+ committee of the American Society of Cell Biology and a member of the Diversity, Equity, and Inclusion committee of the Genetics Society of America. I volunteer for both of these committees because they speak to something I care deeply about, the advocacy for minoritized 1 scientists. I also embody both of these axes of diversity; so, in some way, I am only looking out for myself. This is far from being a scholar or doing “Diversity work.” I fully recognize that there are individuals who have dedicated their lives to this type of work with entire academic fields populated with accomplished scholars. So, I started this year of talks being invited because I am a Black, gay scientist at a time when science was grappling with its own systematic racism, under the guise of my nonexistent Diversity, Equity, and Inclusion work.What has this year actually taught me? The first thing it taught me is that I have been missing out. Prior to George Floyd’s murder, I had only received three seminar invitations from major research institutions and unfortunately all within a year of being posttenure. That is after nearly 6 years in my current position.In giving these talks I got the opportunity to meet with some of the giants in my field, people I have looked up to for years. I received reagents, offers to collaborate, and a litany of great ideas that will help drive my research program for years to come. I left some of these meetings truly inspired and excited to start experiments. These opportunities would have been invaluable to me, pretenure. One could argue, I did not need it. I made it even without this networking and the advantages these visits bring. Before you applaud my ability to persist and be resilient, we should take a deep look at the systems that have forced people who look like me to be doubly resilient. If George Floyd had not been murdered, would any of these invitations have happened? If the previous 6 years are any indication of a trend, I would have to say most certainly not. Why did it take a murder and the reignition of a Civil Rights movement for me to have the type of interactions I now know many of my straight, white counterparts have had from the very beginning of their independent careers? Let me be clear: this is a form of systematic racism, plain and simple.As I began to make the rounds, I was often asked to either share a bit of my journey or include my Diversity, Equity, and Inclusion work in my talks. This sometimes came at the expense of sharing my lab’s work. While I was very happy to do so, this was very much implicit in the invitations I received. At times it did feel that my inclusion was only checking a box, placating the graduate students so that they could see that their department or institution was responding to their demands. This also had the consequence of making me feel as though my science was merely performative. I was being invited to do the Diversity work institutions did not want to do. This is the tension I, and many other minoritized scientists, face. I want to share my experiences with the hopes that the next generation will have it better; but, my scholarly work is not in Diversity, Equity, and Inclusion. I fully recognize that it is my embodied diversity that is bringing me to the table; but, it is the science I want to share.On the first invitation to give a seminar, I promised myself that I was going to be honest. This meant that I would tell the truth about my experience and bare my soul over and over again. What I had not counted on was the emotional toll this would take on me. Reliving my own trauma, on a regular basis, left me emotionally drained after these visits. In one of my “stops” (I use quotes here because these “visits” were all virtual), I met with the queer, person of color (POC), graduate students. This session quickly turned into an emotional support group where I heard stories of mistreatment, racism, and discrimination. It was nearly impossible to maintain my composure. Diversity, Equity, and Inclusion work is clearly extremely important, but, maybe, we could just start by listening to the needs of the students and having a bit of humanity.The trial of Derek Chauvin has come and passed, and much to my surprise, and to the surprise of many other Black people nationwide, he was found guilty and was sentenced to prison (Arango, 2021; Cooper and Fiegel, 2021). This, of course, is not justice, not even close. Justice would mean that George Floyd is still alive and would get to live out his life in the way he chose. We are also at the beginning of the end of the pandemic. In 6 months or less, we may all be returning to life, more or less, as it was before George Floyd, before COVID-19. Does this mean we stop fighting? Does this mean that I, and many other Black scientists, suddenly disappear? For George Floyd, for countless other faceless Black people before him, I sincerely hope not. We need to continue to give Black scientists a platform. We need to ensure that they, too, are given the opportunity to network, collaborate, and interact with the larger scientific community. This means the invitations cannot stop. To further this, we need to ensure that Black scientists are included in every grant review panel, are included on speaker lists at every national and international meeting, are funded, and are in the room where funding, tenure, and other critical decisions are being made. We need to recognize that systematic racism has not gone away with Derek Chauvin’s conviction and sentencing. We need to continue to push forward. And, for all of you young, minoritized scientists (and allies) reading this, demand change and do not take "no" for an answer. I am truly sorry this has fallen on your shoulders, but enough is enough. The next generation of minoritized scientists should be recognized for their science without the additional burden of creating their own space.About the AuthorI am currently an Associate Professor of Biology at Reed College (https://www.reed.edu/biology/applewhite/index.html), which is located in Portland, Oregon. I arrived at Reed in 2014; prior to that, I was a postdoctoral fellow at the University of North Carolina, Chapel Hill. I received my PhD from Northwestern University in Cellular and Molecular Biology and a BS in Biology from the University of Michigan where I was also a 4-year letter winner in track and field. My research focuses on the cytoskeleton where I study cell motility and morphogenesis using Drosophila and Drosophila derived in tissue culture cells to explore actin, microtubules, and molecular motors. My current lab is composed of fierce, determined undergraduate students. I am a member of the American Society of Cell Biology (ASCB) and the current chair of the LGBTQ+ Committee (https://www.ascb.org/committee/lgbtq/).
