BACKGROUND Protein sumoylation is an essential dynamic, reversible post translational modification that plays a role in dozens of cellular activities, especially the regulation of gene expression and the maintenance of genomic stability. Currently, the complexities of sumoylation mechanism can not be perfectly solved by experimental approaches. In this(More)
Nectins are immunoglobulin superfamily adhesion molecules that participate in the organization of epithelial and endothelial junctions. Sharing high homology with the poliovirus receptor (PVR/CD155), nectins were also named poliovirus receptor-related proteins (PRRs). Four nectins and five nectin-like molecules have been identified. Here we describe the(More)
We performed a meta-analysis of 2 genome-wide association studies of coronary artery disease comprising 1,515 cases and 5,019 controls followed by replication studies in 15,460 cases and 11,472 controls, all of Chinese Han ancestry. We identify four new loci for coronary artery disease that reached the threshold of genome-wide significance (P < 5 × 10(-8)).(More)
MicroRNAs are a class of small endogenous noncoding RNAs which play important regulatory roles mainly by post-transcriptional depression. Finding miRNA target genes will help a lot to understand their biological functions. We developed an ensemble machine learning algorithm which helps to improve the prediction of miRNA targets. The performance was(More)
Abnormal proliferation and phenotypic modulation of pulmonary artery smooth muscle cells (PASMC) contributes to the pathogenesis of numerous cardiovascular disorders, including pulmonary arterial hypertension (PAH). The nuclear factor of activated T cells (NFAT) signaling pathway is linked to PASMC proliferation and PAH. MicroRNAs (miRNAs) are small(More)
MicroRNAs are approximately 21nt single-stranded RNAs and function as regulators of gene expression. Previous studies have shown that microRNAs play crucial roles in tumorigenesis by targeting the mRNAs of oncogenes or tumor suppressors. Here we show that brain-enriched miR-128 is down-regulated in glioma tissues and cell lines when compared to normal brain(More)
Recent studies have suggested that oligodendrocyte development is likely to be under the control of a hierarchy of lineage-specific transcription factors. In the developing mouse spinal cord, expression of Olig2, Sox10 and Nkx2.2 is sequentially up-regulated in cells of oligodendrocyte lineage. These transcription factors play essential roles in(More)
Vinculin was identified as a component of adherens junctions 30 years ago, yet its function there remains elusive. Deletion studies are consistent with the idea that vinculin is important for the organization of cell-cell junctions. However, this approach removes vinculin from both cell-matrix and cell-cell adhesions, making it impossible to distinguish its(More)
BACKGROUND Geraniin, an active compound with remarkable antioxidant activity, was isolated from Geranium sibiricum. The present study aimed to investigate whether geraniin has the ability to activate Nrf2, induce antioxidant enzyme expression and protect cells from oxidative damage. METHODS The cells were pretreated with geraniin for 24h and exposed to(More)
The esrB gene of Edwardsiella tarda, which encodes a regulator protein of the type III secretion system, was mutated by the unmarked deletion method and reintroduced by allelic exchange into the chromosome of E. tarda LSE40 by means of the suicide vector pRE112. The LSE40 esrB mutant was highly attenuated when inoculated intraperitoneally into turbot(More)
