Project description:Ureibacillus thermosphaericus strain Thermo-BF is an aerobic, thermophilic bacillus which has been characterized to biosynthesize gold nanoparticles. Here we present the draft genome sequence of Ureibacillus thermosphaericus strain Thermo-BF which consists of a 2,864,162-bp chromosome. This is the first report of a shotgun sequenced draft genome of a species in the Ureibacillus genus.
Project description:The adult mammalian brain is composed of distinct regions that have specialized roles. The BF/POA regions are thought to have an important role in the regulation of sleep/wake behavior. However, genetic markers of the responsible cells for the regulation of sleep/wake behavior are largely unknown. To identify the molecular markers of the BF/POA regions, we sampled the BF/POA regions and compared gene expression in the BF/POA regions with those of other brain regions which we previously reported in the BrainStars (B*) project, in which we sampled ~50 small brain regions, including sensory centers and centers for motion, time, memory, fear, and feeding. We sampled each region every 4 hours for 24 hours, and pooled the sample sets for DNA-microarray assays. We then used informatics to identify candidates for genes with high or low expression in the BF/POA regions. We used our findings to develop an integrated database (http://poabf.brainstars.org/) for exploring genome-wide expression in the adult mouse brain including the BF/POA regions.
Project description:We have shown that pre-incubation with Bifidobacterium bifidum (B. bifidum) strain BF-1, a probiotic strain known to improve H. pylori-associated gastritis, suppresses the induction of IL-8 by the pathogen. To investigate how BF-1 affects gene expression in H. pylori-infected cells, we performed microarray analysis to assess gene expression in epithelial cells, which had been pre-incubated with BF-1 and infected with H. pylori.
