Microarray Analysis of Butyrate Regulated Genes in Colonic Epithelial Cells

Daly, Kristian, Shirazi-Beechey, Soraya P.·2006·DNA and Cell Biology

Abstract

Butyrate is a naturally occurring product of colonic microbial fermentation of dietary carbohydrates that escape hydrolysis in the small intestine. Butyrate plays a significant role in the maintenance of colonic tissue homeostasis by regulating the expression of genes associated with the processes of proliferation, differentiation, and apoptosis. Using microarray analysis, we assessed changes in the expression of 19,400 genes in response to butyrate in a human colonic epithelial cell line. Among these, we have identified 221 potentially butyrate- responsive genes specifically associated with the processes of proliferation, differentiation, and apoptosis. Of these genes, 59 are upregulated and 162 downregulated, in accordance with the known modes of action of butyrate. The changes in the expression levels (up- or downregulation) of many of these genes were found to be opposite to that reported in colon cancer tissue, where the intracellular concentration of butyrate would be reduced due to the decline in expression of the colonic butyrate transporter, MCT1.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
