Counteractive balancing of transcriptome expression involving CodY and CovRS in Streptococcus pyogenes

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.

Comparison of gene expression changes in Streptococcus pyogenes in the presence of zinc

Project description:Manuscript title: Zinc disrupts central carbon metabolism and capsule biosynthesis in Streptococcus pyogenes. Macrophages and neutrophils release free zinc to eliminate phagocytosed bacterial pathogens. The study investigates the effect of how zinc toxicity affects Streptococcus pyogenes. Therefore, a microarray analysis was performed in S. pyogenes cells to determine gene expression changes when exposed to high levels of zinc. We discovered that a pathway involved in tagatose-6-phosphate metabolism was upregulated when the cells are under zinc stress.

Multiple roles of RNase Y in Streptococcus pyogenes mRNA metabolism

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

Insert in CovS Gene Distinguishes a Pharyngeal and a Blood Isolate of Streptococcus pyogenes Found in the Same Individual.

Project description:Expression of the extensive arsenal of virulence factors by Streptococcus pyogenes are controlled by many regulators, of which covR/S is one of the best characterized and can influence ~15% of the genome. Animal models have established that mutants of CovR/S arise spontaneously in vivo resulting in highly invasive organisms. We analyzed a pharyngeal and a blood isolate of S. pyogenes recovered from the same individual 13 days apart. The two isolates varied in many phenotypic properties including speB production, which were reflected in transcriptome analyses. Pulsed field gel electrophoresis, multilocus sequence typing, and partial sequencing of some key genes failed to show any differences except for an 11-base insert in the covS gene in the blood isolate. These results showing that pharyngeal and blood isolates from a single individual which differ by a simple insertion, provide evidence for the model that regulatory gene mutations allow S. pyogenes to invade different niches in the body. A chip study using total RNA recovered from two separate wild-type cultures of group A Streptococcus, Streptococcus pyogenes UH322 and UH328. Each chip measures the expression level of 1865 genes replicated twice from 7 fully sequenced strains of Streptococcus pyogenes (M1_GAS NC_002737; MGAS10394 NC_006086; MGAS315 NC_004070; MGAS5005 NC_007297; MGAS6180 NC_007296; MGAS8232 NC_003485; SSI-1 NC_004606 with fourteen 24-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.
