Project description:In Streptococcus pyogenes, mutation of GidA results in avirulence despite the same growth rate as the wild type. To understand the basis of this effect, global transcription profiling was conducted. Keywords: Wild type vs. GidA mutant Streptococcus pyogenes
Project description:In Streptococcus pyogenes, mutation of the peroxide sensor PerR results in avirulence despite producing hyper-resistance to peroxide stress. To understand the basis of this effect, global transcription profiling was conducted. Keywords: Study of the regulation of gene expression by PerR
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: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.
Project description:Transcriptional profile of Streptococcus pyogenes stk mutant strain JRS2516 vs its wild type parent strain MGAS2221 The RNA prepared from triplicate cultures for the wild type and the stk mutant strains was each labeled with Cy3 and hybridized to duplicate arrays. Reference RNA consisted of pooled RNA for the wild type and stk mutant, labeled with Cy5.
Project description:Rgg-dependent transcriptional regulation in SF370 Streptococcus pyogenes strain was analyzed during post-exponential phase of growth Keywords: rgg mutant Microarray analysis was performed using RNA samples isolated from both wild-type SF370 and SF370 rgg mutant strains during post-exponential phase of growth
Project description:Whole genome expression profile comparing MGAS315 treated with XIP pheromone versus vehicle-treated cells Interpretations are described further in the manuscript to be submitted: authors Mashburn-Warren, Morrison, and Federle. Title: The Cryptic Competence Pathway in Streptococcus pyogenes is Controlled by a Peptide Pheromone. A two chip study using total RNA recovered from three separate cultures of Streptococcus pyogenes MGAS315, each treated with either XIP pheromone or with vehicle; RNA preparation of cultures receiving same type of treatment were pooled using equivalent amounts of RNA from each culture. RNA pools were fluorescently labeled and hybridized to arrays designed to the S. pyogenes NZ131 genome.
Project description:Rgg-dependent transcriptional regulation in Streptococcus pyogenes strains MGAS5005 and CS101 was analyzed during post-exponential phase of growth Keywords: strain comparion, post-exponential growth, rgg mutant Microarray analysis was performed using RNA samples isolated from wild-type MGAS5005 and CS101 strains as well as their rgg mutant strains during post-exponential phase of growth
