Project description:H3K27Ac enrichment in intestinal epithelial cells from intestine of germ-free and segmented filamentous bacteria (SFB)-monoassociated mice. Intestinal epithelial cells were harvested from the terminal ileum of germ-free or SFB mice. Chromatin immunoprecipitation was performed with anti-H3K27Ac. Sequencing was performed using the Illumina HiSeq2500. Reads were mapped to the mm10 genome using Bowtie.
Project description:Members of the genus Acinetobacter drag attention due to their importance in microbial pathology and biotechnology. OmpA is a porin with multifaceted functions in different species of Acinetobacter. In this study we identified this protein in Acinetobacter sp. SA01, an efficient phenol degrader strain, in different cellular and sub-cellular compartments (such as OM, OMV, biofilm and extracellular environment). Differential expression of proteins, including OmpA, under two conditions of phenol and ethanol supplementation was assessed using shotgun proteomics.
Project description:Expression in intestinal epithelial cells from intestine of germ-free and segmented filamentous bacteria (SFB)-monoassociated mice during infection. Intestinal epithelial cells were harvested from the terminal ileum of germ-free or SFB mice infected with Citrobacter rodentium for 6 days. RNA was isolated using RNeasy Kit (Qiagen). Sequencing was performed using the Illumina HiSeq2500. Reads were mapped to the mm10 genome using Bowtie.
Project description:To investigate SFB-host interactions and the host response to SFB, we compared gene expression profiles in terminal ileal mucosa collected from 5 SFB-positive and 5-negative age-matched patients identified from SFB PCR. We observed that 472 genes were different between the two groups (P < 0.05). Among them, 290 genes were up-regulated and 182 were down-regulated. GO biological pathway analysis of up-regulated genes revealed positive regulation of T-cell differentiation and activation pathways were enhanced (P < 0.001), suggesting that SFB colonization stimulated the human immune system, specifically T-cell maturation. Indeed, enhanced expression of Cd3e, Ifng, IL10, Foxp3 was observed in terminal ileal mucosa of 5 SFB-positive patients.

To find immune-related genes significantly expressed (p < 0.05) between SFB-positive and -negative
