Project description:Data independent analysis of proteome of patient derived epithelial cell from five regions, duodenum, jejunum, ileum, colon and rectum.
Project description:Affymetrix U95Av2 expression data from human intestinal cells (Caco-2) and tissues from all intestinal segments (duodenum, jejunum, ileum, colon). Entries contain the search terms glycosylase, phosphorylase, cytochrome or nucleoside, which were relevant to our search for enzymes capable of cleaving the N-glycosidic bond of nucleoside analog drugs.
Project description:Results of RNA-seq of normal C57BL/6 small intestinal epithelial cells sorted from duodenum, jejunum and ileum separately. Samples are named as follow; mouse replicate number-duodenum(1), jejunum(2) or ileum(3). For example, 1-1, 1-2 and 1-3 representing duodenum, jejunum and ileum respectively from mouse replicate number 1.
Project description:This SuperSeries is composed of the following subset Series: GSE4256: Colon transcriptional response to quercetin in WT and POR-null mice; GSE4257: Ileum transcriptional response to quercetin in WT and POR-null mice; GSE4258: Jejunum transcriptional response to quercetin in WT and POR-null mice; GSE4259: Liver transcriptional response to quercetin in WT and POR-null mice Experiment Overall Design: Refer to individual Series
Project description:We report the expression profiles of three stem-cell varieties derived from the ileum and jejunum, focusing on gene signatures that are consistent in all stem cells of an intestinal location. We find that intestinal stem cells establish and maintain a regional identity that is discernable through gene expression patterns consistent with intestinal function particular to that region.
Project description:The occurrence of many neonatal inflammatory intestinal diseases in preterm infants highlights the susceptibility of the immature intestine to respond inadequately to nutrient and microbes. A better understanding of the functional intestinal development is essential for the design of optimal treatments ensuring survival and growth of premature infants. The purpose of this study was to evaluate the gene expression profiles of the developing human ileum and colon at mid-gestation. Our results showed that more than 11% of the genes were differentially expressed between ileum and colon. Pathway analysis revealed an even higher level of transcriptional dissimilarity between the developing ileum and the colon including 35% of the significant cellular, molecular and physiological functions and 85% of the canonical pathways. Segment-specific/over-expressed functions in the ileum included a number of amino acid, vitamin and mineral metabolisms and lymphoid tissue structure and development reflecting the high level of maturity of the small intestine as compared to the colon in which cell cycle, cell morphology and actin cytoskeleton, integrin and ERK/MAPK signaling were the predominant functions. All together, functional clustering analysis of the differentially expressed genes revealed important functional difference between the two segments namely to an unexpected relative immaturity of the colon.
Project description:To establish better understanding of cells found in jejunal and ileal Peyer's patches of pigs, we utilized single-cell RNA sequencing scRNA-seq and spatial transcriptomics to recover and analyze cells and spatial regions from sections of jejunum and ileum containing Peyer's patches. Cells identified via single-cell RNA sequencing included B, T/innate lymphoid cell, myeloid, epithelial, and stromal lineage cells. Spatial dots recovered via spatial transcriptomics belonged to regions including villi, crypts, interfollicular/parafollicular zones, follicles, and muscularis. Overall, results provide new information on regional localization and transcriptional profiles of cells in the pig small intestine.
