Bacteroides thetaiotaomicron ameliorates colon inflammation in preclinical models of Crohn’s Disease [Bacteroides]

Project description:Analysis of the Bacteroides thetaiotaomicron(BT) transcriptome during co-culture with Caco-2 intestinal epithelial cells To identify potential bacterial protein(s) involved in the anti-inflammatory effect of BT in colitis, BT was incubated with Caco-2 human intestinal epithelial cells for 2 hours, and bacterial gene expression was assessed on a Bacteroides thetaiotaomicron VPI-5482 specific microarray. Forty-three BT genes were up-regulated by five-fold or more and of these, twenty genes encoded hypothetical proteins.

Genome-wide RNA-seq of Bacteroides thetaiotaomicron VPI-5482 with Bacteroides phage challenge

Project description:Purpose: Examining the transcriptome of Bacteroides thetaiotaomicron VPI-5482 challenged with Bacteroides phage to assess surface molecule expression changes Methods: Bacteroides thetaiotaomicron was grown in BPRM in vitro or Germ-Free mice were monocolonized with Bacteroides thetaiotaomicron and gavaged with ARB25 phage. Fold change was calculated as live phage versus heat-killed phage treated samples with n=3 biological replicates. Once cells reached an optical density corresponding to mid-log phase growth (absorbance between 0.4-0.5), RNA was isolated and rRNA depleted. Samples were multiplexed for sequencing on the Illumina HiSeq platform at the University of Michigan Sequencing Core. Data was analyzed using Arraystar software (DNASTAR, Inc.) using DEseq2 normalization with default parameters. Genes with significant up- or down-regulation were determined by the following criteria: genes with an average fold-change >5-fold and with at least 2/3 biological replicates with a normalized expression level >1% of the overall average, and a p-value < 0.05 (t test with Benjamini-Hochberg correction) Results: Specific capsule expression was increased in wild-type B. thetaiotaomicron during phage infection in vitro and in vivo. Many corresponding in vivo genes were upregulated as well as other surface layer proteins.

Bacteroides thetaiotaomicron ameliorates colon inflammation in preclinical models of Crohn’s Disease [mouse colon]

Project description:Analysis of the gut transcriptome as affected by treatment with Bacteroides thetaiotaomicron in a mouse model of IBD Here, we report analysis of the gut transcriptome in IL10KO mice after treatment with Bacteroides thetaiotaomicron (BT). Comparative transcriptome analysis of ascending colon tissue of IL10KO and IL10KO/BT-treated mice showed differential expression of a wide range of genes associated with inflammatory responses between the two treatment groups. Expression of proinflammatory genes and genes involved in pathogen recognition was particularly lower in IL10KO/BT mice.
