Plant viral movement proteins (MPs) enable viruses to pass through cell walls by increasing the size exclusion limit (SEL) of plasmodesmata (PD). Here, we report that the ability of Cucumber mosaic virus (CMV) MP to increase the SEL of the PD could be inhibited by treatment with the actin filament (F-actin)-stabilizing agent phalloidin but not by treatment(More)
Orange-spotted grouper iridovirus (OSGIV) was the causative agent of serious systemic diseases with high mortality in the cultured orange-spotted grouper, Epinephelus coioides. Here we report the complete genome sequence of OSGIV. The OSGIV genome consists of 112,636 bp with a G+C content of 54%. 121 putative open reading frames (ORF) were identified with(More)
The viral proteases have proven to be the most selective and useful for removing the fusion tags in fusion protein expression systems. As a key enzyme in the viral life-cycle, the main protease (M(pro)) is most attractive for drug design targeting the SARS coronavirus (SARS-CoV), the etiological agent responsible for the outbreak of severe acute respiratory(More)
Advanced glycation end products (AGEs) boost the generation of reactive oxygen species (ROS) in glomerular mesangial cells (GMCs), and thereby play important roles in diabetic nephropathy (DN). Sirtuin 1 (Sirt1), a protein deacetylase, is known to markedly protect cells from oxidative stress (OSS) injury. Based on the critical involvements of AGEs and Sirt1(More)
OBJECTIVE To investigate whether circulating levels of fibroblast growth factor 21 (FGF21), which previously has been shown to be elevated in obesity, could predict the development of type 2 diabetes in a 5.4-year, population-based, prospective study. RESEARCH DESIGN AND METHODS Baseline plasma FGF21 levels were measured using an enzyme-linked(More)
The immunohistochemical analysis was used to evaluate the expression of PD-L1 in 109 non-small cell lung cancer (NSCLC) tissues and para-tumor tissues. Associations between expressed PD-L1 and tumor histological types, degree of differentiation, and lymph node metastasis were calculated, and overall survival was assessed. Meanwhile, immunohistochemistry and(More)
AIM To evaluate the correlation between a polymorphism of PD-L1 gene and the susceptibility of non-small cell lung cancer (NSCLC) in a Chinese population. METHODS A total of 293 Chinese patients with NSCLC and 293 age and sex matched controls of the same ethnic origin were enrolled in this study. A/C polymorphism at position 8923 in intron 4 of PD-L1 gene(More)
BACKGROUND The pandemic of obesity is a global public health concern. Most studies on obesity are skewed toward high-income and urban settings and few covers low-income populations. This study focused on the prevalence of overweight and obesity and their correlations with blood lipids/metabolites/enzymes (bio-indicators) in a rural community typical of(More)
Insulin-like growth factor (IGF) signaling is involved in oral squamous cell carcinoma (OSCC), but IGF-1 receptor (IGF-1R)-mediated intricate regulatory networks among molecular interactions and signalling path ways in OSCC remain unclear. Here, we found that overexpression of IGF-1R and insulin receptor substrate-2 (IRS-2) was negatively associated with(More)
Hypoxia-inducible factors (HIFs) are transcription factors that respond to changes in oxygen tension in the cellular environment. In this study, we identified full-length cDNAs of HIF-1α, HIF-2α and HIF-3α in an endangered hypoxia-sensitive fish species, Chinese sucker. The HIF-1α/2α/3α cDNAs are 3890, 3230 and 3374 bp in length, encoding 780, 782 and 632(More)
