Project description:We performed RNAseq on ulcers and distant normal tissue from biopsy-wounded wild-type and Bmp4-overexpressing (Vil1-Cre;Rosa26-Bmp4) mice to investigate differences in gene expression between tissue states and genotypes. Biopsy wounding was performed by taking three biopsies from well-separated areas in the colon wall using forceps. Small tissue pieces were excised from the ulcers and distant normal colon tissue and collected for RNA sequencing.
Project description:Tamoxifen-inducible conditional knockout (CKO) mice were generated to explore the function of Gcn1 in adult mice using the Cre/loxP system. To analyze the function of GCN1 in the intestinal epithelium, we compared the whole cell proteome of jejunum harvested from GCN1 CKO mice with that of wild-type mice.

Project description:Tamoxifen-inducible conditional knockout (CKO) mice were generated to explore the function of Gcn1 in adult mice using the Cre/loxP system. To analyze the function of GCN1 in the intestinal epithelium, we compared the whole cell proteome of duodenum harvested from GCN1 CKO mice with that of wild-type mice.
Project description:Gene expression in the colonic mucosa of wild-type and p38a-knockout intestinal epithelial cells (IECs) were compared. C57BL/6 wild-type mice, and intestinal epithelial cell-specific p38a-knockout mice on a C57BL/6 background were used for isolation of colonic mucosa
Project description:Mice lacking 3-hydroxy-3-methylglutaryl-coenzyme A reductase (Hmgcr) in intestinal villus and crypt epithelial cells were generated using a Villin-Cre transgene. Label free proteome profiling was measure for Wild type and KO mouse.
Project description:Toll-like receptor 4 (TLR4), the receptor of gram-negative bacterial endotoxin, is present on the intestinal epithelium and plays pivotal roles in intestinal epithelial differentiation and host defense. To better understand TLR4 on the intestinal epithelium, the ileum samples from wild type mice and mice lacking TLR4 in the intestinal epithelium (TLR4ΔIEC) were subjected to RNA-seq analysis to interrogate the transcriptome. We mapped about 20 million sequence reads per sample to the mouse genome and identified 86477 genes in the ileum of wild type and TLR4ΔIEC mice. 455 genes were differentially expressed between wild type and TLR4ΔIEC mice and 1037 genes were absent either from wild type or TLR4ΔIEC mice with G-factor value 0.015 and Δ cutoff value 0.54. Pathway analysis via IPA indicated some impacted canonical KEGG pathways such as DNA replication, PPAR signaling, Toll-like receptor signaling, cytokine-cytokine interaction, adherens junction, Jak-STAT signaling, and tight junction.
Project description:At the epigenetic level, lncRNAs play important roles in cell differentiation and function. We identified novel long-stranded non-coding RNA (GM1082) in intestinal epithelial cells.We used high-throughput sequencing to detail the global programme of gene expression and identified distinct classes of up or down regulated genes in intestinal epithelial cells of wild-type mice, germ-free mice and wild-type mice infected with S. Typhimurium.
Project description:We performed a transcriptome comparison of double-negative developing thymocytes from the DN3-4 population, from mice overexpressing the transcription factor Duxbl and wild type mice
