An avian-origin human-infecting influenza (H7N9) virus was recently identified in China. We have evaluated the viral hemagglutinin (HA) receptor-binding properties of two human H7N9 isolates, A/Shanghai/1/2013 (SH-H7N9) (containing the avian-signature residue Gln(226)) and A/Anhui/1/2013 (AH-H7N9) (containing the mammalian-signature residue Leu(226)). We(More)
As the most aggressive malignant primary human brain tumor, glioblastoma is noted with extremely poor patient survival. Previous studies have demonstrated that expression of matrix metalloproteinase-9 (MMP9) in glioblastoma cells is critical for cancer metastasis. However, the molecular signaling pathways that control MMP9 activation remain undefined. Here,(More)
The understanding of genetic basis for Philadelphia-negative myeloproliferative neoplasm (MPN) has got much progress in recent years. But the effect of CALR vs. JAK2V617F mutations on the clinical progression and prognosis of primary fibrosis (PMF) remains relatively obscure. In this meta-analysis, we searched Pubmed, Embase, and Web of Science databases(More)
Wogonin, a plant-derived flavone, has been shown recently to have antitumor effects. However, the mechanisms that wogonin inhibits tumor angiogenesis are not well known. In this study, we investigated the effects of wogonin on expression of hypoxia-inducible factor-1α (HIF-1α) and secretion of vascular endothelial growth factor (VEGF) in tumor cells. We(More)
Genetic polymorphisms of p53 codon 72 are thought to have significant effects on the metabolism of environmental carcinogens and thus on lung cancer risk, but the reported results are not always consistent. The aim of this study is to investigate the relationship between p53 codon 72 genetic polymorphisms and tobacco use and lung cancer risk in a Chinese(More)
Wogonin, a naturally occurring monoflavonoid extracted from the root of Scutellaria baicalensis Georgi, has been reported for its anti-oxidant activity. However, it is still unclear whether wogonin can inhibit oxidant-induced vascular permeability. In this study, we evaluated the effects of wogonin on H2O2-induced vascular permeability in human umbilical(More)
Drosophila has eight Hox proteins, and they require factors acting in parallel to regulate different segmental morphologies. Here we find that the Drosophila gene split ends (spen), has a homeotic mutant phenotype, and appears to encode such a parallel factor. Our results indicate that spen plays two important segment identity roles. One is to promote(More)
BACKGROUND Cytokeratin 19-derived CYFRA21-1 is an acceptable lung cancer biomarker. However, whether CYFRA21-1 correlates with lung cancer circulating tumor cells (CTCs) remains unclear. METHODS CTCs in 42 lung cancer patients and 10 nonmalignant pulmonary disease patients were isolated by means of an EpCAM-independent enrichment strategy. Correlation of(More)
MicroRNAs are highly conserved noncoding RNA that negatively modulate protein expression at a posttranscriptional and/or translational level and are deeply involved in the pathogenesis of several types of cancers. To date, the potential microRNAs regulating the growth and progression of osteosarcoma are not fully identified yet. Previous reports have shown(More)
Deinococcus geothermalis is a radioresistant and moderate thermophilic bacterium. Little was known about the membrane or membrane associated proteins of this bacterium. This study established the membrane subproteome profile of D. geothermalis, using 1-D PAGE and LC-MS/MS analysis following Triton X-114 detergent extraction. A total of 552 proteins from the(More)
