The eukaryotic transcription factor NF-kappa B plays a central role in the induced expression of human immunodeficiency virus type 1 and in many aspects of the genetic program mediating normal T-cell activation and growth. The nuclear activity of NF-kappa B is tightly regulated from the cytoplasmic compartment by an inhibitory subunit called I kappa B(More)
Extraembryonic ectoderm-derived factors instruct the pluripotent epiblast cells to develop toward a restricted primordial germ cell (PGC) fate during murine gastrulation. Genes encoding Bmp4 of the Dpp class and Bmp8b of the 60A class are expressed in the extraembryonic ectoderm and targeted mutation of either results in severe defects in PGC formation. It(More)
Human infection associated with a novel reassortant avian influenza H7N9 virus has recently been identified in China. A total of 132 confirmed cases and 39 deaths have been reported. Most patients presented with severe pneumonia and acute respiratory distress syndrome. Although the first epidemic has subsided, the presence of a natural reservoir and the(More)
BACKGROUND Seven persons in one family living in eastern China developed fever and thrombocytopenia during May 2007, but the initial investigation failed to identify an infectious etiology. In December 2009, a novel bunyavirus (designated severe fever with thrombocytopenia syndrome bunyavirus [SFTSV]) was identified as the cause of illness in patients with(More)
Influenza A viruses (IAVs), particularly H1N1, H5N1 and H7N9, pose a substantial threat to public health worldwide. Here, we report that MIR2911, a honeysuckle (HS)-encoded atypical microRNA, directly targets IAVs with a broad spectrum. MIR2911 is highly stable in HS decoction, and continuous drinking or gavage feeding of HS decoction leads to a significant(More)
Cytochrome P450s metabolize the naturally occurring nephrotoxin aristolochic acid. Using liver-specific cytochrome P450 reductase-null mice we found that a low but lethal dose of aristolochic acid I was ineffective in wild-type mice. Induction of hepatic CYP1A by 3-methylcholanthrene pretreatment markedly increased the survival rate of wild type mice given(More)
OBJECTIVE To determine whether the novel avian influenza H7N9 virus can transmit from person to person and its efficiency. DESIGN Epidemiological investigations conducted after a family cluster of two patients with avian H7N9 in March 2013. SETTING Wuxi, Eastern China. PARTICIPANTS Two patients, their close contacts, and relevant environments. Samples(More)
Chronic hepatitis B therapy with nucleos(t)ide analogues, particularly tenofovir or adefovir, may affect renal function. To date, there has not been a head-to-head controlled study to assess estimated glomerular filtration rate (eGFR) fluctuations in nucleos(t)ide-treated CHB patients. We aimed to evaluate the long-term effects of nucleos(t)ide on eGFR in(More)
Influenza A (H7N9) virus has been causing human infections in China since February 2013, raising serious concerns of potential pandemics. Previous studies demonstrate that human infection is directly linked to live animal markets, and that the internal genes of the virus are derived from H9N2 viruses circulating in the Yangtze River Delta area in Eastern(More)
An avian influenza virus, A/environment/Zhenjiang/C13/2013(H5N6), was isolated from a live poultry market in eastern China. Phylogenetic analysis showed that the isolate was a novel reassortant virus with a neuraminidase (NA) gene from H6N6 viruses and the other seven genes from H5N1 viruses, which may pose a potential threat to human and animal health.
