Project description:The Clostridioides difficile toxins TcdA and TcdB are responsible for diarrhea and colitis. The aim of this project was to explore the effects of the toxins on epithelial barrier function and the molecular mechanisms for diarrhea and inflammation. RNA-seq of toxin-treated intestinal cell monolayers was performed to describe the C. difficile-mediated effects. mRNA profiles from intestinale epithelial cells were generated by deep sequencing using Illumina NovaSeq 6000. This data provide the basis for subsequent upstream regulator analysis.
Project description:We isolated suppressors of a ∆ddl mutant strain with constitutively active allelles of the vanS gene. VanS is a histidine kinase of a two-component system that regulates expression of the vanG operon. Transcriptomes of wild-type and ∆ddl vanS (R334L) strains were compared.
