Regulatory RNAs in pathogenic Epsilonproteobacteria
Non-coding RNAs and RNA-protein (RNP) complexes play central roles in diverse physiological processes in all kingdoms of life. Research in our lab focuses on RNA-based processes in the two pathogenic Epsilonproteobacteria Helicobacter pylori, the cuasative agent of gastric cancer, and the related food-borne pathogen Campylobacter jejuni. We are especially interested in the roles of small, regulatory RNAs (sRNAs) and RNPs in virulence control as well as novel mechanisms of gene regulation. For example, we have discovered new connections between so-called phase-variation at length variable DNA repeats and post-transcriptional regulation. I will present our work on sRNAs from H. pylori and C. jejuni that target variable G-repeats and regulate genes involved in host colonization as well as antibiotic sensitivity. Moreover, we recently identified a sRNA that is itself regulated by a phase-variable repeat and acts as a central regulator of the major virulence factors of H. pylori.
