Project description:The alkaliphilic halotolerant bacterium Bacillus sp. N16-5 often faces salt stress in its natural habitats. One-color microarrays was used to investigate transcriptome expression profiles of Bacillus sp. N16-5 adaptation reactions to prolonged grown at different salinities (0%, 2%, 8% and 15% NaCl) and the initial reaction to suddenly alter salinity from 0% to 8% NaCl. Salt induced gene expression was measured when culture was grown on different salinities (0%, 2%, 8% and 15% NaCl) to mid-logarithmic phase. And salt induced gene expression was also measured at 0 min, 10 min, 30 min, 60min, 120min after a sudden change salinity from 0% to 8% NaCl.
Project description:Alkaline hemicellulytic bacteria Bacillus sp. N16-5 has abroad substrate spectrum and exhibits great growth ability on complex carbohydrates. In order to get insight into its carbohydrate utilization mechanism, global transcriptional profiles were separately determined for growth on glucose, fructose, mannose, galactose, arabinose, xylose, galactomannan, xylan, pectin and carboxymethyl cellulose by using one-color microarrays. Substrate induced gene expression was measured when culture was grown on glucose, fructose, mannose, galactose, arabinose, xylose, galactomannan, xylan and CMC to mid-logarithmic phase.
Project description:Corneal epithelial stem cells reside in the limbus that is the transitional zone between the cornea and conjunctiva, and are essential to maintain the homeostasis of corneal epithelium. However, their characterization is poorly understood. Therefore, we constructed gene expression profiles of limbal epithelial SP and non-SP cell using RNA-sequencing. As a result, limbal epithelial SP cells have immature cell phenotypes with endothelial/mesenchymal cell markers, while limbal epithelial non-SP cells have epithelial progenitor cell markers. Overall design: Examination of rabbit limbal epithelial SP and non-SP cells
Project description:This series represents the work described in the publication Bacillus subtilis Genome Diversity by Earl et al. (Journal of Bacteriology, accepted) Keywords: comparative genomic hybridization Overall design: The aim of this study was to examine genome diversity among Bacillus subtilis species members. Strains were chosen from within both recognized subspecies and one close relative, Bacillus vallismortis.
