Project description:Whole genone expression profile comparing wild-type NZ131 to serR deletion mutant, grown in C-medium Mutants and interpretation are described further in the manuscript to be submitted: LaSarre and Federle, 2010. Title: Regulation and Consequence of Serine Catabolism in Streptococcus pyogenes. A two chip study using total RNA recovered from three separate wild-type cultures of Streptococcus pyogenes NZ131 and three separate mutant cultures of Streptococcus pyogenes NZ131 seR-, pooled following RNA extraction
Project description:Streptococcus pyogenes (group A Streptococcus, GAS) responds to environmental changes in a manner that results in an adaptive regulation of the transcriptome. Global transcriptional regulators are able to integrate important extracellular and intracellular information and are responsible for modulation of the transcriptional network. The roles of several global transcriptional regulators in adaptation and virulence gene expression have been described. In this study we used microarray to investigate the regulatory roles of CodY and CovRS played in Streptococcus pyogenes. keywords: genetic modification Streptococcus pyogenes NZ131 wild-type cells, ΔcodY, ΔcovRS and ΔcodYcovRS strains were grown in C-medium until mid-exponential phase or early-stationary phase. The transcriptional profile of the whole genome was examined with microarray.
Project description:Streptococcus pyogenes (Group A streptococcus, GAS) is an important human pathogen that causes a variety of infectious diseases and sequelae. Recent studies showed virulence factor expression was controlled at multiple levels, including the post-transcriptional regulation. In this study, we examined the global half-lives of S. pyogenes mRNAs and explored the role RNase Y played in mRNA metabolism with microarray analysis. key word: genetic modification
