The ENCyclopedia Of DNA Elements (ENCODE) Project aims to identify all functional elements in the human genome sequence. The pilot phase of the Project is focused on a specified 30 megabases (È1%) of the human genome sequence and is organized as an international consortium of computational and laboratory-based scientists working to develop and apply(More)
The roles of many sigma factors are unclear in regulatory mechanism of secondary metabolism in Streptomyces. Here, we report the regulation network of a group 3 sigma factor, WhiGch, from a natamycin industrial strain Streptomyces chattanoogensis L10. WhiGch regulates the growth and morphological differentiation of S. chattanoogensis L10. The whiG ch(More)
Quorum sensing molecular γ-butyrolactones (GBL) are widely distributed among the genus Streptomyces. Their cognate receptors have been demonstrated to control secondary metabolism and/or morphological differentiation. ScgA is responsible for the biosynthesis of GBL in Streptomyces chattanoogensis. According to the genome-wide transcriptome analysis of the(More)
The current study was conducted to establish animal models (including mouse and ferret) for the novel avian-origin H7N9 influenza virus. A/Anhui/1/2013 (H7N9) virus was administered by intranasal instillation to groups of mice and ferrets, and animals developed typical clinical signs including body weight loss (mice and ferrets), ruffled fur (mice),(More)
The microRNA-29 family (miRNA-29s) has three mature members, miR-29a, miR-29b and miR-29c, which have been implicated in the regulation of the pathogenesis of Alzheimer's disease (AD). The miR-29 family members exhibit differential regulation in various diseases and different subcellular distribution. In the present study, we initially investigated(More)
On 19 February 2013, the first patient infected with a novel influenza A H7N9 virus from an avian source showed symptoms of sickness. More than 349 laboratory-confirmed cases and 109 deaths have been reported in mainland China since then. Laboratory-confirmed, human-to-human H7N9 virus transmission has not been documented between individuals having close(More)
Salinomycin, a polyether antibiotic produced by Streptomyces albus, is widely used in animal husbandry as an anticoccidial drug and growth promoter. Situated within the salinomycin biosynthetic gene cluster, slnR encodes a LAL-family transcriptional regulator. The role of slnR in salinomycin production in S. albus was investigated by gene deletion,(More)
In previous studies of hand, foot, and mouth disease patients fatally infected with enterovirus 71 (EV71), the distribution of viral protein, but not the genome, was determined. To understand the pathogenesis of EV71, however, it is important to investigate the spread of the viral genome. There have been no pathological studies of in situ EV71 viral RNA in(More)
