Causes and Consequences of Changes in Nutrient Structure in the Jiaozhou Bay

Concentrations and ratios of nutrients in Jiaozhou Bay, China, have changed much in the past decades, with trends indicating an increase in nitrogen and a decrease in silicate. Statistical analysis has shown that the long-term variations of nutrients are associated with agricultural activities, precipitation, and anthropogenic factors. Stoichiometric calculations indicate that the nutrient structure has become more and more unbalanced. There has been almost no possibility for nitrogen limitation since the 1980s, the probability of P limitation has increased, and the probability of Si limitation has also increased markedly from the 1980s to the 1990s. As a consequence of changes in nutrient structure, a decrease in the abundance of net phytoplankton was evident, whereas total chlorophyll a levels have remained roughly unchanged at around 3.55μg/L. Thus, it is likely that smaller species have taken the niche vacated by the larger species. Changes in phytoplankton size and species composition may ultimately lead to various functional and structural changes at the system level.

Changes in DNA base sequences in the mutant of Arabidopsis thaliana induced by low-energy N+ implantation

Arabidopsis thaliana (L.) Heynh has many advantages for genome analysis, including a short generation time, small size, large number of offspring, and a relatively small nuclear genome in comparison to other angiosperms and contains a low proportion of repetitive DNA comparatively. Furthermore, the analysis of the completed genome sequence of A. thaliana has been reported[1]. Low-energy ion implantation has attracted more and more attention from researchers in China and Japan since recent s…     

Hemicentins： What have we learned from worms？

Hemicentins are conserved extracellular matrix proteins discovered in Caenorhabditis elegans, with orthologs in all vertebrate species including human and mouse. Hemicentins share a single, highly conserved amino-terminal von Willebrand A domain, followed by a long （〉40） stretch of immunoglobulin repeats, multiple tandem epidermal growth factors and a fibulin-like carboxy-terminal module. C. elegans has a single hemicentin gene that has pleiotropic functions in transient cell contacts that are required for cell migration and basement membrane invasion and in stable contacts at hemidesmosome-mediated cell junctions and elastic fiber-like structures. Here, we summarize what is known about the function ofhemicentin in C. elegans and discuss implications for hemicentin function in other species.     

Translational Bioinformatics:Past,Present, and Future

Though a relatively young discipline, translational bioinformatics (TBI) has become a key component of biomedical research in the era of precision medicine. Development of high-throughput technologies and electronic health records has caused a paradigm shift in both healthcare and biomedical research. Novel tools and methods are required to convert increasingly voluminous datasets into information and actionable knowledge. This review provides a definition and contex-tualization of the term TBI, describes the discipline’s brief history and past accomplishments, as well as current foci, and concludes with predictions of future directions in the field.     

β-adrenergic modulation of in vivo long-term potentiation in area CA1 and its role in spatial learning in rats

The hippocampus plays a key role in declarative learning and memory [1]. Hippocampal long-term potentiation (LTP) is a type of synaptic plasticity that has been widely studied as a syn-aptic mechanism underlying learning and memory[27]. It has been reported that in vitro LTP in area CA1 is subjected to b-adrenergic modulation. For example, the theta-pulse stimulation (510 Hz), a neutral frequency not modifying synaptic strength, can elicit a robust LTP in area CA1 in slice when the b-adr…

A journey to a brighter future

It has been 15 years since Cell Research was launched in 1990. At that time, Chinese scientists rarely published their work in non-Chinese journals, and China did not have a major English journal of its own in life sciences. In a way, Cell Research was born at the right time, in the right place, and with the right kind of people guiding its development. The rise of Cell Research as China＇s leading journal publishing peer-reviewed articles in basic life sciences has paralleled the rapid development of the Chinese economy in general and the science and technology sector in particular over the same period. The current economic trend should allow even more rapid advances in the life sciences which will ensure a healthy growth of Cell Research in years to come. Thus, we are confident that Cell Research has a brighter future.     

Recent Progress Using High-throughput Sequencing Technologies in Plant Molecular Breeding

High-throughput sequencing is a revolutionary technological innovation in DNA sequencing.This technology has an ultra-low cost per base of sequencing and an overwhelmingly high data output.High-throughput sequencing has brought novel research methods and solutions to the research fields of genomics and post-genomics.Furthermore,this technology is leading to a new molecular breeding revolution that has landmark significance for scientific research and enables us to launch multi-level,multi-faceted,and multi-extent studies in the fields of crop genetics,genomics,and crop breeding.In this paper,we review progress in the application of high-throughput sequencing technologies to plant molecular breeding studies.     

Autophagy and cancer

Autophagy is a homeostatic and evolutionarily conserved mechanism of self-digestion by which the cells degrade and recycle long-lived proteins and excess or damaged organelles.Autophagy is activated in response to both physiological and pathological stimuli including growth factor depletion,energy deficiency or the upregulation of Bcl-2 protein expression.A novel role of autophagy in various cancers has been proposed.Interestingly,evidence that supports both a positive and negative role of autophagy in the pathogenesis of cancer has been reported.As a tumor suppression mechanism,autophagy maintains genome stability,induces senescence and possibly autophagic cell death.On the other hand,autophagy participates in tumor growth and maintenance by supplying metabolic substrate,limiting oxidative stress,and maintaining cancer stem cell population.It has been proposed that the differential roles of autophagy in cancer are disease type and stage specific.In addition,substrate selectivity might be involved in carrying out the specific effect of autophagy in cancer,and represents one of the potential directions for future studies.

Cloning and characterization of nanos gene in silkworm Bombyx mori

Gene nanos is a maternal posterior group gene required for normal development of abdominal segments and the germ line in Drosophila. Expression of nanos-related genes is associated with the germ line in a broad variety of other taxa. In this study, the 5＇-RACE method and the in silico cloning method are used to isolate the new nanos-like gene of Bombyx mor/and the gene obtained is analyzed with bioinformatics tools. The putative protein is expressed in Escherichia coli and the antiserum has been produced in New Zealand white rabbits. The result shows that the nanos cDNA is 1,913 bp in full length and contains a 954 bp open reading frame. The deduced protein has 317 amino acid residues, with a predicted molecular weight of 35 kDa, isoelectric point of 5.38, and contains a conserved nanos RNA binding domain. The conserved region of the deduced protein shares 73% homology with the nanos protein conserved region of Honeybee （Apis mellifera）. This gene has been registered in the GenBank under the accession number EF647589. One encoding sequence of the nanos fragment has been successfully expressed in E. coli. Western blotting analysis indicates that homemade antiserum can specifically detect nanos protein expressed in prokaryotic cells.
