Project description:Vibrio parahaemolyticus is the leading bacterial cause for seafood-related gastroenteritis worldwide. As an intestinal pathogen, V. parahaemolyticus competes with other commensal bacteria for the same pool of nutrients. The major source of nutrition for intestinal bacteria is intestinal mucus. We wanted to determine the expression profile of wild-type V. parahaemolyticus in mouse intestinal mucus and then perform a differential expression analysis in a ∆rpoN deletion mutant.

Project description:The development and severity of inflammatory bowel diseases (IBD) and other chronic inflammatory conditions can be influenced by host genetic and environmental factors, including signals derived from commensal bacteria. However, the mechanisms that integrate these diverse cues remain undefined. Here we demonstrate that intestinal epithelial cells (IECs) isolated from IBD patients exhibit decreased expression of the epigenome-modifying enzyme histone deacetylase 3 (HDAC3). Further, genome-wide analyses of murine IECs that lack HDAC3 (HDAC3ΔIEC) revealed that HDAC3 deficiency resulted in dysregulated gene expression coupled with alterations in histone acetylation. Critically, conventionally-housed HDAC3ΔIEC mice demonstrated loss of Paneth cells, impaired IEC function and alterations in the composition of intestinal commensal bacteria. In addition, HDAC3ΔIEC mice exhibited significantly increased susceptibility to intestinal damage and inflammation, indicating that epithelial expression of HDAC3 plays a central role in maintaining intestinal homeostasis. Strikingly, rederivation of HDAC3ΔIEC mice into germ-free conditions revealed that dysregulated IEC gene expression, Paneth cell homeostasis, and intestinal barrier function were largely restored in the absence of commensal bacteria. Collectively, these data indicate that the HDAC3 is a critical factor that integrates commensal bacteria-derived signals to calibrate epithelial cell responses required to establish normal host-commensal relationships and maintain intestinal homeostasis. Analyses of histone acetylation in primary IECs from HDAC3FF (3 biologic replicates) and HDAC3ΔIEC (3 biologic replicates) mice were conducted utilizing ChIP-seq for H3K9Ac.

As an intestinal pathogen, V. parahaemolyticus competes with other commensal bacteria for the same pool of nutrients. The major source of nutrition for intestinal bacteria is intestinal mucus. We wanted to determine the expression profile of wild-type V. parahaemolyticus in mouse intestinal mucus and then perform a differential expression analysis in a ∆luxO deletion mutant, in which the high cell density quorum sensing regulator OpaR is constitutively expressed and low cell density regulator AphA is repressed.

Project description:As a good niche for bacterial growth, appendix plays a very important role in maintaining and protecting intestinal symbiotic flora. Appendectomy will lead to intestinal microecological disorders. Therefore, we put forward the hypothesis that "appendectomy leads to intestinal microecological disorders and then increases the risk of colorectal cancer". In this study, the feces of normal controls, appendectomy and patients with colorectal cancer were collected, and the specific changes of intestinal flora after appendectomy were explored in detail from the level of family, genus and species by macrogenomic sequencing. Then through functional gene analysis, metabolic pathway analysis and other methods to explore the molecular mechanism of colorectal cancer risk changes and the changes of microflora involved, and verified by mouse fecal bacteria transplantation animal experiment.
