M1002 protect mice from DSS-induced colitis through regulation of HIF-1 signaling and the Gut Microbiota in DSS-Induced Colitis in Mice

Project description:Abstract. Ulcerative colitis (UC) is an intestinal disease characterized by chronic recurrent inflammation, but the underlying mechanism remains undefined and requires in-depth exploration. The aim of the present study was to investigate the biological effects of a small molecular compound M1002 of oxygen-sensing signaling pathway on dextran sulfate sodium (DSS)-induced intestinal inflammation colitis mouse models. It was found that the protective effects of M1002 on DSS-induced colitis. To determine how M1002 exerted its protective effect in DSS-induced colitis, we compared the global gene expression profiles in the gut between DSS control and M1002 treatment colitis mouse groups by RNA-Seq. The results demonstrated that HIF-1 signaling pathway-related genes were significantly upregulated in the gut of M1002 treatment colitis mice, whereas the Inflammatory bowel disease signaling pathway, the TNF signaling pathway, and Cytokines and inflammatory response signaling pathway related genes were significantly downregulated in the M1002 treatment group. 16S rRNA gene sequencing demonstrated remarkable variations in the composition of gut microbiota between DSS control and M1002 treatment colitis mice. Compared with DSS control colitis mice, the relative abundance of Eubacterium_nodatum and Halomonas in the gut microbiota was significantly increased at genus level in the gut of M1002 treatment colitis mice. Based on these findings, we tend to conclude that M1002 might alleviate DSS-induced gut injury in mice by regulation of HIF-1 signaling and up-regulating Eubacterium_nodatum and Halomonas.

Colon gene expression signatures in wild type and Card9-/-mice exposed to DSS induced colitis

Project description:It is crucial to decipher the host-microbiota interactions as they are involved in intestinal homeostasis and diseases. Caspase Recruitment Domain 9 (Card9) is an inflammatory bowel disease (IBD) susceptibility gene coding for an adapter protein for innate immunity toward many microorganisms. Card9 mediates colitis recovery via interleukin 22 pathway activation and Card9-/- mice have enhanced susceptibility to colitis. To reveal the mechanisms responsible of this defect in Card9-/-mice, we compared colon transcriptomics in WT and Card9-/- mice before and during DSS-induced colitis. Mice transcriptomes clusterized according to the genotype supporting a pattern clearly different in WT and Card9-/- mice. The number of up-regulated genes at day 7 was largely higher in Card9-/- compared to WT mice. Pathway analyses of the induced transcripts showed a dominance of immune-related pathway with a stronger signal in Card9-/- mice. Interestingly, NOD-like receptor signaling pathway, in which CARD9 is involved, was an exception with weaker activation in Card9-/- than in WT mice. During the recovery period at day 12, pathways involved in cell proliferation and replication were significantly activated in WT compared to Card9-/- mice confirming the healing defect in Card9-/- mice. For the induction of colitis, mice were given drinking water supplemented with 2% (w/v) Dextran sulphate sodium (DSS) for 7 days, then allowed to recover by drinking water alone for 5 additional days. 3 mice of each groups (WT and Card9-/-) were sacrified before DSS administration. 5 WT mice and 4 Card9-/- mice were sacrified 7 days after DSS administration and 5 mice of each group were sacrified at day 12.

GsMTx4 suppresses pro-inflammatory gene expression in DSS-induced colitis in mice.

Project description:The spider venom-derived peptide GsMTx4 specifically inhibits mechanosensory ion channels. It has been reported that GsMTx4 plays an immunoregulatory role in several inflammatory conditions. Therefore, we administrated GsMTx4 to mice with dextran sodium sulfate (DSS)-induced acute colitis, to explore whether it regulates inflammatory responses in colitis.

Enterobacter ludwigii protects DSS-induced colitis through choline-mediated immune tolerance

Project description:Commensal intestinal bacteria play key roles in regulating cells mediating immune tolerance; however, bacterial strains and related metabolites directly involved in this regulation are largely unknown. Here, using a mouse model of dextran sulfate sodium (DSS)-induced colitis combined with different antibiotic treatment, Enterobacter ludwigii, abundant in microbiota of mice treated with metronidazole, was screened out to have prophylactic and therapeutic effects on DSS-induced colitis with or without the presence of complex intestinal bacteria. E. ludwigii was demonstrated to induce CD103+DC and Treg-mediated immune tolerance for colitis remission using in vitro and in vivo experiments. Moreover, choline, one of E. ludwigii metabolites, was identified to increase DCs’ immune tolerance to promote Treg differentiation. E. ludwigii was found to induce DCs’ immune tolerance ability for Treg differentiation through choline and α7nAChR-mediated RA and TGF-β upregulation, resulting in protecting mice against DSS-induced colitis. This study provides potential therapeutic approaches for IBD.

Methods : DSS-induced colitis was performed on Axin1flfl (WT) and Vil CreERT2;Axin1fl/fl (Axin1KOΔIEC) mice by giving 3% DSS dissolved in drinking water for 7 days and subsequently placed on regular water for recovery before sacrifice at Day 7 and D13. Methods : AOM/DSS-induced colorectal tumorigenesis was performed on Axin1flfl (WT) and Vil CreERT2;Axin1fl/fl (Axin1KOΔIEC) mice that were sacrificed at day 100 post-AOM injection to collect colorectal tumors. Methods : Colonic mRNA profiles of WT and Axin1KOΔIEC mice were generated by deep sequencing using Illumina NextSeq 500 instrument (150base-lengths read V2 chemistry in a paired-end mode)
