We have sequenced the genome of Shigella flexneri serotype 2a, the most prevalent species and serotype that causes bacillary dysentery or shigellosis in man. The whole genome is composed of a 4 607 203 bp chromosome and a 221 618 bp virulence plasmid, designated pCP301. While the plasmid shows minor divergence from that sequenced in serotype 5a, striking(More)
Transmembrane protein 166 (TMEM166) is a lysosomal/endoplasmic reticulum-associated protein found in various species where it acts as a regulator of programmed cell death, mediating both autophagy and apoptosis. In the present study, we investigated the role of TMEM166 following MCAO injury in rats to determine whether the structural damages following(More)
The FZD3 protein is a transmembrane receptor for secreted Wnt glycoproteins involved in the Wnt signal transduction cascades. The alteration of Wnt signal transduction cascades has been thought to be involved in producing the cytoarchitectural defects observed in schizophrenia. Because the human FZD3 gene is mapped to chromosome 8p21, which is a potential(More)
Autophagy and endoplasmic reticulum (ER) stress are both tightly regulated cellular processes that play central roles in various physiological and pathological conditions. Recent reports have indicated that ER stress is a potent inducer of autophagy. However, little is known about the underlying molecular link between the two processes. Here we report a(More)
In the present study, a cell-based high-throughput assay is established to identify novel human genes associated with cell viability. The assay relies on the down-regulation of Renilla luciferase (pRL) activity in a 96-well format. In addition, 2-color fluorescence probes were used to distinguish living and dead cells. As the positive control, the authors(More)
The tumor suppressor p53 is at the hub of cellular signaling networks that are activated by stress signals including DNA damage. In the present study, we showed that programmed cell death 5 (PDCD5) bound to p53 by glutathione S-transferase (GST)-pulldown, co-immunoprecipitation and co-localization assays. PDCD5 enhanced the stability of p53 by antagonizing(More)
Current gene co-expression databases and correlation networks do not support cell-specific analysis. Gene co-expression and expression correlation are subtly different phenomena, although both are likely to be functionally significant. Here, we report a new database, ImmuCo (http://immuco.bjmu.edu.cn), which is a cell-specific database that contains(More)
BACKGROUND Alternative polyadenylation sites within a gene can lead to alternative transcript variants. Although bioinformatic analysis has been conducted to detect polyadenylation sites using nucleic acid sequences (EST/mRNA) in the public databases, one special type, single-block EST is much less emphasized. This bias leaves a large space to discover(More)
Gene expression is highly dynamic and plastic. We present a new immunological database, ImmuSort. Unlike other gene expression databases, ImmuSort provides a convenient way to view global differential gene expression data across thousands of experimental conditions in immune cells. It enables electronic sorting, which is a bioinformatics process to retrieve(More)
BACKGROUND RNF122 is a recently discovered RING finger protein that is associated with HEK293T cell viability and is overexpressed in anaplastic thyroid cancer cells. RNF122 owns a RING finger domain in C terminus and transmembrane domain in N terminus. However, the biological mechanism underlying RNF122 action remains unknown. RESULTS In this study, we(More)
