Viral community structures in complex agricultural soils are largely unknown. Electron microscopy and viromic analyses were conducted on six typical Chinese agricultural soil samples. Tailed bacteriophages, spherical and filamentous viral particles were identified by the morphological analysis. Based on the metagenomic analysis, single-stranded DNA viruses represented the largest viral component in most of the soil habitats, while the double-stranded DNA viruses belonging to the Caudovirales order were predominanted in Jiangxi-maize soils...

We analyzed the genetic polymorphisms of 54 mitochondrial DNA (mtDNA) variants in Chinese Xibe ethnic minority group. A total of 137 unrelated healthy volunteers from Chinese Xibe group were the objects of our study. Among the selected loci, there were 51 variable positions including transitions and transversions, and single nucleotide transitions were common (83.93%) versus transversions. These variations defined 64 different mtDNA haplotypes exclusive of (CA)n and 9 bp deletion variation. The haplotype diversity and discrimination power in Xibe population were 0...

We developed a systematic approach to map human genetic networks by combinatorial CRISPR-Cas9 perturbations coupled to robust analysis of growth kinetics. We targeted all pairs of 73 cancer genes with dual guide RNAs in three cell lines, comprising 141,912 tests of interaction. Numerous therapeutically relevant interactions were identified, and these patterns replicated with combinatorial drugs at 75% precision. From these results, we anticipate that cellular context will be critical to synthetic-lethal therapies...

Locusta has strong fly wings to ensure its long distance migration, but the molecular mechanism that regulates the Locusta wing development is poorly understood. To address the developmental mechanism of the Locusta flying wing, we cloned the Dpp target gene spalt (sal) and analyzed its function in wing growth in the Locusta. The Locusta wing size is apparently reduced with vein defects when sal is interfered by injection of dsRNA, indicating that sal is required for locust wing growth and vein formation. This function is conserved during the Drosophila wing development...

Since 2013, highly pathogenic (HP) H5N6 influenza A viruses (IAVs) have emerged in poultry in Asia, especially Southeast Asia. These viruses have also caused sporadic infections in humans within the same geographic areas. Active IAV surveillance in wild birds sampled in Guangdong province, China from August 2014 through February 2015 resulted in the recovery of three H5N6 IAVs. These H5N6 IAV isolates possess the basic amino acid motif at the HA1-HA2 cleavage site that is associated with highly pathogenic IAVs infecting chickens...

Sialic acid-binding Ig-like lectin-9 (Siglec-9) is a novel sialic acid-binding member of the immunoglobulin superfamily, and is broadly expressed on immune cells, which can inhibit both innate and adaptive immune responses through immunoreceptor tyrosine-based inhibitory motifs. However, the exact role of Siglec-9 in the pathogenesis of rheumatoid arthritis (RA) remains unknown. In this study, we determined soluble Siglec-9 (sSiglec-9) levels in the serum and synovial fluid of RA patients, and evaluated the relation between sSiglec-9 levels and clinical factors...

The BET proteins are major transcriptional regulators and have emerged as new drug targets, but their functional distinction has remained elusive. In this study, we report that the BET family members Brd2 and Brd4 exert distinct genomic functions at genes whose transcription they co-regulate during mouse T helper 17 (Th17) cell differentiation. Brd2 is associated with the chromatin insulator CTCF and the cohesin complex to support cis-regulatory enhancer assembly for gene transcriptional activation. In this context, Brd2 binds the transcription factor Stat3 in an acetylation-sensitive manner and facilitates Stat3 recruitment to active enhancers occupied with transcription factors Irf4 and Batf...

Taxol (paclitaxel) and vinblastine (VBL) are both efficacious chemotherapeutic agents that target the microtubules of tumor cells, but each functions in a mutual antagonistic manner. Op18/stathmin is a small molecular phosphoprotein which promotes depolymerization of microtubules. Non-small cell lung cancer (NSCLC) NCI-H1299 cells were employed to compare the curative effects of VBL and Taxol and explore the correlation between drug sensitivity and Op18/stathmin signaling. The present study found that VBL obviously promoted cellular apoptosis and initiated activation of caspase 3 and 9, and inhibited cell proliferation and colony formation, as well as cell migration in the NCI-H1299 cells in contrast with Taxol...

Crimean-Congo hemorrhagic fever virus (CCHFV) is a highly pathogenic tick-borne virus with a fatality rate of up to 50% in humans. CCHFV is widely distributed in countries around the world. Outbreaks of CCHFV infection in humans have occurred in prior years in Xinjiang Province, China. Epidemiological surveys have detected CCHFV RNA in ticks and animals; however, few isolates were identified. In this study, we identified and isolated a new CCHFV strain from Hyalomma asiaticum asiaticum ticks collected from north of Tarim Basin in Xinjiang, China...

BACKGROUND AND PURPOSE: Metformin, a small molecule antihyperglycaemic agent, is well-known as an AMP-activated protein kinase (AMPK) activator and protects against cardiac fibrosis. However, the underlying mechanisms remain elusive. Transforming growth factor-β1 (TGFβ1) is a key cytokine mediating cardiac fibrosis. Here, we investigated the effects of metformin on TGFβ1 production induced by angiotensin II (AngII) and the underlying mechanisms. EXPERIMENTAL APPROACH: Wild-type and AMPKα2(-/-) C57BL/6 mice were subcutaneously injected with metformin or saline and infused with AngII (3 mg kg(-1) day(-1) ) for 7 days...

One new bibenzyl (1) and one new phenanthrene (2), together with two known bibenzyls (3-4) and four known diarylheptanoids (5-8) were isolated from the rhizomes of Dioscorea zingiberensis. The structures of 1-2 were elucidated by spectroscopic methods including 1D and 2D NMR. Phenols 1-8 were evaluated for their anti-pancreatitic activities on sodium taurocholate (NaT)-induced pancreatic acinars necrosis. Notably, 0.5mM of compound 6 exhibited comparable inhibitory effect with 5mM of caffeine. Furthermore, compound 6 prevented the ATP depletion and excessive ROS production which could be also involved in mitochondria-mediated injuries in acute pancreatitis...
