DSS Microbiota LC-MS/MS

Project description:In the DSS-induced colitis model, the epithelial damage and resulting inflammation is restricted to the colon, with a potential influence on the microbial composition in the adjacent cecum. Several studies have reported changes of the gut microbiota in the DSS-induced colitis model and other mouse models of IBD. Furthermore, metaproteomics analysis of the gut microbiome in a mouse model of Crohn’s disease demonstrated that disease severity and location are microbiota-dependent, with clear evidence for the causal role of bacterial dysbiosis in the development of chronic ileal inflammation. We have developed a refined model of chronic DSS-induced colitis that reflects typical symptoms of human IBD without a risky body weight loss usually observed in DSS models [Hoffmann et al., submitted]. In this study, we used metaproteomics to characterize the disease-related changes in bacterial protein abundance and function in the refined model of DSS-induced colitis. To assess the structural and functional changes, we applied 16S rRNA gene sequencing and metaproteomics analysis of the intestinal microbiota in three different entities of the intestinal environment, i.e. colon mucus, colon content and cecum content.

Characterizing phenotypic data of Peromyscus leucopus compared to C57BL/6J Mus musculus and diversity outbred (DO) Mus musculus.

Project description:Translational research is commonly performed in the C57B6/J mouse strain, chosen for its genetic homogeneity and phenotypic uniformity. Here, we evaluate the suitability of the white-footed deer mouse (Peromyscus leucopus) as a model organism for aging research, offering a comparative analysis against C57B6/J and diversity outbred (DO) Mus musculus strains. Our study includes comparisons of body composition, skeletal muscle function, and cardiovascular parameters, shedding light on potential applications and limitations of P. leucopus in aging studies. Notably, P. leucopus exhibits distinct body composition characteristics, emphasizing reduced muscle force exertion and a unique metabolism, particularly in fat mass. Cardiovascular assessments showed changes in arterial stiffness, challenging conventional assumptions and highlighting the need for a nuanced interpretation of aging-related phenotypes. Our study also highlights inherent challenges associated with maintaining and phenotyping P. leucopus cohorts. Behavioral considerations, including anxiety-induced responses during handling and phenotyping assessment, pose obstacles in acquiring meaningful data. Moreover, the unique anatomy of P. leucopus necessitates careful adaptation of protocols designed for Mus musculus. While showcasing potential benefits, further extensive analyses across broader age ranges and larger cohorts are necessary to establish the reliability of P. leucopus as a robust and translatable model for aging studies.

Multi-Omics Insights into the Mechanism of Liver Injury in Dextran Sulfate Sodium-Induced Colitis

Project description:Liver injury is a common complication of inflammatory bowel disease (IBD). However, the mechanisms of liver injury development are not clear in IBD patients. Gut microbiota is thought to be engaged in IBD pathogenesis. Here, by an integrated analysis of host transcriptome and colonic microbiome, we have attempted to reveal the mechanism of liver injury in colitis mice. In this study, dextran sulfate sodium (DSS) -induced mice colitis model was constructed. Liver and colon transcriptome results showed that immune response and lipid metabolism-related pathways were dramatically altered, while DNA damage repair-related pathways were only significantly down-regulated in the colon. The microbiota of DSS-treated mice underwent strong transitions. Correlation analyses identified genes associated with liver and colon injury, whose expression was associated with the abundance of liver and gut health-related bacteria Collectively, the results indicate that the liver injury in colitis mice may be related to the intestinal dysbiosis and host-microbiota interactions. These findings may provide new insights for identifying potential targets for the treatment of IBD and its induced liver injury.

Toll-like receptor 2 deficiency exacerbates dextran sulfate sodium (DSS)-induced intestinal injury by Marinifilaceae dependent attenuating cell cycle signaling

Project description:Ulcerative colitis (UC) is an intestinal pathology characterized by chronic recurrent inflammation, which requires in-depth exploration of its mechanisms. To investigate the biological effects of TLR2 on DSS-induced intestinal inflammation in mice, we constructed the WT and TLR2-KO colitis mice model. We found TLR2-KO mice were severely susceptible to DSS-induced colitis. To determine how TLR2 exerted a protective effect in DSS-induced colitis, we compared the global gene expression profiles in the gut between WT and TLR2-KO mice by RNA-Seq. Results suggested that cell cycle pathway-related genes were significantly downregulated in gut of TLR2-KO colitis mice. 16S rRNA gene sequencing demonstrated remarkable variation in the composition of gut microbiota between WT and TLR2-KO colitis mice. Compared with WT colitis mice, the relative abundance of Marinifilaceae, Rikenellaceae, Desulfovibrionaceae, Tannerellaceae, Ruminococcaceae, Clostridia, Mycoplasmataceae were significantly higher in the gut of TLR2-KO colitis mice at family level. Moreover, we found that the relative abundance of Marinifilaceae was negatively correlated with the expression of cell cycle signaling related genes by microbiome diversity-transcriptome collaboration analysis. We came to this conclusion: TLR 2-KO exacerbated DSS-induced intestinal injury by Marinifilaceae dependent attenuating cell cycle signaling.

Transcriptional profiling of murine distal colon from C57BL/6 (WT) and Stat2KO mice during acute DSS colitis.

Project description:Experimental colitis was induced in mice by the administration of 2% (w/v) Dextran sulfate sodium salt (DSS, colitis grade, 36-50kDa, MP Biomedicals) in the drinking water for 7 days followed by normal drinking water w/o DSS. Distal colons were collected two days later.
