Systems Biology Brings Life Sciences Closer——Report on the China-UK Systems Biology Workshop 2005

The China-UK Systems held during June 20-21 Biology Workshop 2005 was in the National Science Park of Zhejiang University, Hangzhou, China. It was organized by the Institute of Bioinformatics, Zhejiang University, and was initiated by Prof. Dr. Jun Zhu （Zhejiang University） and Prof. Dr. John Findlay （University of Leeds, UK）. The workshop was part of the program called UK-China Partners in Science, a one-year campaign that was initiated by the British government to explore more collaborations between UK and China on science and technology. It was attended also by a representative of this program, Mr. Frank Yuan, senior science ＆ innovation officer. The idea of the workshop was to bring together experts with specialists in systems biology in order to promote the ＂natural partnership＂ between scientists from the two countries. The most important items of systcms biology considered at the workshop were： （1） New technologies and advances in systems biology; （2） Research developments in genomics and proteomics; （3） New methodologies and software in computational biology; （4） Research collaboration on systems biology between China and UK.

In Memoriam： To our beloved friend,colleague, and Overseas Chinese Entomologists Association （OCEA） member,Professor Que Lan （1959-2014）

Dr. Lan Que was born in 1959 in Wuhan, the capital city of Hubei province, China. It may have been her childhood experience as a 13-year-old girl with a shaking body burning under blankets as she battled with malaria vectored by mosquitoes that fueled her determination to erad- icate this dreaded disease, as she stated many years later in an interview with Grow--Wisconsin＇s Magazine for the Life Sciences （2010, http：//grow.cals.wisc.edu/health/the- exterminator）. Lan＇s enthusiasm for biology, microbiology, entomology, and mosquitoes control quickly became the focus of her higher education and professional career. She received her B.S. in Microbiology from Wuhan University, China, in 1982 and her pursuit of her childhood dream of fighting malaria took her halfway across the world first to Canada, where she earned her M.S. in Biology from Brock University in 1988 and then on to the University of Minnesota in the United States for her Ph.D. in Entomology, which she was awarded in 1993. After 5 years＇ postdoctoral research in Developmental Biology,

Individual variation in dispersal associated behavioral traits of the invasive Chinese mitten crab （Eriocheir sinensis,H. Milne Edwards, 1854） during initial invasion of Lake V~inern,Sweden

Understanding and predicting species range-expansions and biological invasions is an important challenge in modem ecology because of rapidly changing environments. Recent studies have revealed that consistent within-species variation in behavior （i.e. animal personality） can be imperative for dispersal success, a key stage in the invasion process. Here we investigate the composition and correlation of two important personality traits associated with invasion success, activity and boldness, and how they are connected to sex and individual size in a newly colonised population of the Chinese mitten crab Eriocheir sinensis in Lake Vanem, Sweden. We found no effect of sex or size on behavioral expressions orE. sinensis but a clear positive correlation between boldness and activity. In addition, this study generates important baseline data for monitoring behavioral develop ment, and thereby changing ecological impact, of an invading population over time. This has implications for predicting ecological effects of invasive species as well as for managing ecological invasions.

THE MARINE COPEPODA FROM THE SPAWNING GROUNDOF PNEUMATOPHORUS JAPONICUS (HOUTTUYN)OFF CHEFOO, CHINA

Under the direction of the Committee for the Exploration of Economic Fi-sheries Resources of the Yellow Sea and Peichihli Bay, an investigation of thebreeding habits of the scomber, Pneumalophorus japonicus(Houttuyn),was carriedout in the years 1953-1955. The annual visit of the scomber to the spawning groundoff Chefoo every spring brings about a flourishing fishery there. Since the spawningmigration of marine fishes is closely related to the changes of various environ-mental factors, the plankton, considered as one of the important factors of thebiological environment, was also included in the scope of exploration. Copepods are well known as one of the most important groups of zooplankton,not only because of their numerous species, but also on account of the part they play     

菌物学新旧的纽带（英文）

<正>John Webster in lectures to his students and discussions with colleagues always emphasized the ecological dimension to mycology,exemplified in his books[1].He always highlighted historic details both in nomenclature and in the understanding of the intricacies of fungal biology as admirably shown in his editing of Ainsworth’s Brief Biographies of British     

The function and regulation of TET2 in innate immunity and inflammation

TET2,a member of ten-eleven translocation(TET)family as a-ketoglutarate-and Fe2+-dependent dioxygenase catalyzing the iterative oxidation of 5-methylcytosine(5mC),has been widely recognized to be an important regulator for normal hematopoiesis especially myelopoiesis.Mutation and dysregulation of TET2 contribute to the development of multiple hematological malignancies.Recent studies reveal that TET2 also plays an important role in innate immune homeostasis by promoting DNA demethylation or independent of its enzymatic activity.Here,we focus on the functions of TET2 in the initiation and resolution of inflammation through epigenetic regulation and signaling network.In addition,we highlight regulation of TET2 at various molecular levels as well as the correlated inflammatory diseases,which will provide the insight to intervene in the pathological process caused by TET2 dysregulation.     

ABC transporters, neural stem cells and neurogenesis--a different perspective

Stem cells intrigue. They have the ability to divide exponentially, recreate the stem cell compartment, as well as create differentiated cells to generate tissues. Therefore, they should be natural candidates to provide a renewable source of cells for transplantation applied in regenerative medicine. Stem cells have the capacity to generate specific tissues or even whole organs like the blood, heart, or bones. A subgroup of stem cells, the neural stem cells （NSCs）, is characterized as a self-renewing population that generates neurons and glia of the developing brain. They can be isolated, genetically manipulated and differentiated in vitro and reintroduced into a developing, adult or a pathologically altered central nervous system. NSCs have been considered for use in cell replacement therapies in various neurodegenerative diseases such as Parkinson＇s disease and Alzheimer＇s disease. Characterization of genes with tightly controlled expression patterns during differentiation represents an approach to understanding the regulation of stem cell commitment. The regulation of stem cell biology by the ATP-binding cassette （ABC） transporters has emerged as an important new field of investigation. As a major focus of stem cell research is in the manipulation of cells to enable differentiation into a targeted cell population; in this review, we discuss recent literatures on ABC transporters and stem cells, and propose an integrated view on the role of the ABC transporters, especially ABCA2, ABCA3, ABCB 1 and ABCG2, in NSCs＇ proliferation, differentiation and regulation, along with comparisons to that in hematopoietic and other stem cells.     

Stem cell therapy for heart failure:Medical breakthrough,or dead end?

Heart failure continues to be one of the leading causes of morbidity and mortality worldwide.Myocardial infarction is the primary causative agent of chronic heart failure resulting in cardiomyocyte necrosis and the subsequent formation of fibrotic scar tissue.Current pharmacological and non-pharmacological therapies focus on managing symptoms of heart failure yet remain unable to reverse the underlying pathology.Heart transplantation usually cannot be relied on,as there is a major discrepancy between the availability of donors and recipients.As a result,heart failure carries a poor prognosis and high mortality rate.As the heart lacks significant endogenous regeneration potential,novel therapeutic approaches have incorporated the use of stem cells as a vehicle to treat heart failure as they possess the ability to self-renew and differentiate into multiple cell lineages and tissues.This review will discuss past,present,and future clinical trials,factors that influence stem cell therapy outcomes as well as ethical and safety considerations.Preclinical and clinical studies have shown a wide spectrum of outcomes when applying stem cells to improve cardiac function.This may reflect the infancy of clinical trials and the limited knowledge on the optimal cell type,dosing,route of administration,patient parameters and other important variables that contribute to successful stem cell therapy.Nonetheless,the field of stem cell therapeutics continues to advance at an unprecedented pace.We remain cautiously optimistic that stem cells will play a role in heart failure management in years to come.     

HIV and HCV： from Co-infection to Epidemiology, Transmission, Pathogenesis, and Treatment

Human immunodeficiency virus (HIV) is the infectious agent causing acquired immu-nodeficiency syndrome (AIDS),a deadliest scourge of human society. Hepatitis C virus (HCV) is a major causative agent of chronic liver disease and infects an estimated 170 million people worldwide,resulting in a serious public health burden. Due to shared routes of transmission,co-infection with HIV and HCV has become common among individuals who had high risks of blood exposures. Among hemophiliacs the co-infection rate accounts for 85%; while among injection drug users (IDU) the rate can be as high as 90%. HIV can accelerate the progression of HCV-related liver disease,particularly when immunodeficiency has developed. Although the effect of HCV on HIV infection is controversial,most studies showed an increase in mortality due to liver disease. HCV may act as a direct cofactor to fasten the progression of AIDS and decrease the tolerance of highly active antiretroviral therapy (HARRT). Conversely,HAART-related hepatotoxicity may enhance the progression of liver fibrosis. Due to above complications,co-infection with HCV and HIV-1 has imposed a critical challenge in the management of these patients. In this review,we focus on the epidemiology and transmission of HIV and HCV,the impact of the two viruses on each other,and their treatment.     

Philadelphia chromosome-positive leukemia stem cells in acute lymphoblastic leukemia and tyrosine kinase inhibitor therapy

Leukemia stem cells(LSCs),which constitute a minority of the tumor bulk,are functionally defined on the basis of their ability to transfer leukemia into an immunodeficient recipient animal.The presence of LSCs has been demonstrated in acute lymphoblastic leukemia(ALL),of which ALL with Philadelphia chromosome-positive(Ph+).The use of imatinib,a tyrosine kinase inhibitor(TKI),as part of front-line treatment and in combination with cytotoxic agents,has greatly improved the proportions of complete response and molecular remission and the overall outcome in adults with newly diagnosed Ph+ ALL.New challenges have emerged with respect to induction of resistance to imatinib via Abelson tyrosine kinase mutations.An important recent addition to the arsenal against Ph+ leukemias in general was the development of novel TKIs,such as nilotinib and dasatinib.However,in vitro experiments have suggested that TKIs have an antiproliferative but not an antiapoptotic or cytotoxic effect on the most primitive ALL stem cells.None of the TKIs in clinical use target the LSC.Second generation TKI dasatinib has been shown to have a more profound effect on the stem cell compartment but the drug was still unable to kill the most primitive LSCs.Allogeneic stem cell transplantation(SCT) remains the only curative treatment available for these patients.Several mechanisms were proposed to explain the resistance of LSCs to TKIs in addition to mutations.Hence,TKIs may be used as a bridge to SCT rather than monotherapy or combination with standard chemotherapy.Better understanding the biology of Ph+ ALL will open new avenues for effective management.In this review,we highlight recent findings relating to the question of LSCs in Ph+ ALL.     

The role of Bax and Bak in cell death in the nervous system

It is well recognized that cell death plays an important role during the maturation of the nervous system as well as in many neurological diseases. Apoptosis has been shown to be important particulary during embryogenesis as a means to eliminating unwanted neurons. Severed axons have also been shown to degenerate in an organized fashion termed Wallerian degeneration. Excitotoxic death is another form of cell death in the nervous system which is induced by high concentrations of neurotransmitters such as glutamate. It is not known whether the same molecular mechanisms underlie these different forms of cell death in the nervous system. The Bax-/-Bak-/- double knock-out mouse provides an ideal system to study     

Granulocyte-macrophage colony-stimulating factor （GM-CSF） and T-cell responses： what we do and don＇t know

Granulocyte-macrophage colony-stimulating factor （GM-CSF） is an important hematopoietic growth factor and immune modulator. GM-CSF also has profound effects on the functional activities of various circulating leukocytes. It is produced by a variety of cell types including T cells, macrophages, endothelial cells and fibroblasts upon receiving immune stimuli. Although GM-CSF is produced locally, it can act in a paracrine fashion to recruit circulating neutrophils, monocytes and lymphocytes to enhance their functions in host defense. Recent intensive investigations are centered on the application of GM-CSF as an immune adjuvant for its ability to increase dendritic cell （DC） maturation and function as well as macrophage activity. It is used clinically to treat neutropenia in cancer patients undergoing chemotherapy, in AIDS patients during therapy, and in patients after bone marrow transplantation. Interestingly, the hematopoietic system of GM-CSF-deficient mice appears to be normal; the most significant changes are in some specific T cell responses. Although molecular cloning of GM-CSF was carried out using cDNA library oft cells and it is well known that the T cells produce GM-CSF after activation, there is a lack of systematic investigation of this cytokine in production by T cells and its effect on T cell function. In this article, we will focus mainly on the immunobiology of GM-CSF in T cells.
