Project description:gamma delta intraepithelial lymphocytes were isolated from the colons of DSS-treated and untreated mice. Total RNAs were isolated and compared by Affymetrix DNA microarray. Duplicate comparisons were made between DSS-treated and untreated gamma delta intraepithelial lymphocytes.

Project description:Intestinal intraepithelial gamma-delta T cells (iIEL gd T cells) constitute a peculiar subset of T lymphocytes located in the gut epithelial barrier involved in intestinal homeostasis. To date, type 1 and type 17 TCR gamma-delta T cells have been well characterized into two functional categories based on phenotypic and functional markers e.g. CD44 and CD27. However, It remains to be determined how to classify iIEL gamma T cells based on commonly used markers. We addressed this question by comparing the transcriptomes of mouse iIEL gamma-delta T cells with distinct functionally well-described gamma-delta T cells present in the periphery.
Project description:Gamma-delta T cells prevent CRC. To understand the criticial role of Gamma-delta T cells in CRC, AOM-DSS tumors from mice lacking TCRγδ and with TCRγδ cells were used to isolate epithelial cells to study gene expression by bulk RNA sequencing.
Project description:DSS-induced colitis mice were treated with PBS, A. muciniphila secreting extracellular vesicles (SEV) via gavage every day. Mice lymphocytes of colon tissues from each of the indicated group (Colitis and SEV) in were collected. Then CD4+ T cells are isolated from lymphocytes. These cells were submitted for scRNA-seq.
Project description:To investigate the detailed molecular mechanisms for the regulatory role of Nik in colitis, microarray gene expression analysis was performed on colon tissue RNA isolated from 3-month-old untreated control and DSS treated Nik+/+ and NikΔIE mice.
Project description:Adamts12-deficient mice undergo more severe colitis than WT mice after induction with DSS. We used microarrays to determine the gene expression differences between Adamts12-deficient and WT mice during ulcerative colitis induced with DSS (dextran sodium sulfate) Fragments of distal colon from DSS-treated (2% DSS during 7 days and 1 day of recovery) and untreated Adamts12-deficient and WT mice were obtained for RNA extraction and hybridiztion with Affymetrix microarrays
Project description:Expression profile of colon mucosa of F344 rats treated with 5% DSS during five days vs colon mucosa of F344 rats pre-treated for 20 days with resveratrol 1mg/kg/day and during the five days of 5% DSS administration Keywords: Inflammation experiment Two conditions experiment, colon mucosa of F344 rats treated 5% DSS for 5d vs colon mucosa of F344 rats pretreated with 1mg/kg/day resv + 5% DSS for 5d. 8 Biological samples for each group
Project description:To discover possible molecular mechanisms mediated by GM-CSF that may be involved in regeneration of the colon epithelium after DSS-induced injury we performed whole-genome wide mRNA microchip analysis of isolated crypt epithelial cells from unchallenged and DSS-challenged WT and GM-CSF-/- mice. Total RNA was prepared from isolated crypts obtained from colons of GM-CSF deficient mice and WT littermates treated or untreated with 1.5%DSS for 6 days. Three biological replicates were performed for each experimental condition.
