Transcription profiling of rat dextran sulphate sodium-induced colitis model

ABSTRACT: Background & Aims: Dextran sulphate sodium (DSS) induced colitis in rats is one of the most widely used models of inflammatory bowel disease. Animal models can provide new insights into the pathogenesis of intestinal inflammation, which is still unknown. We have performed a genomic analysis of the DSS rat colitis including an acute and a recovery phase. Methods: Expression profile of 6 control rats were compared with colitic rats at day 1 every other day until day 23 after DSS treatment using the GeneChip Rat Genome 230 2.0 Array (Affymetrix). Functional and pathways analysis were made with the differentially expressed genes. Experiment Overall Design: Experimental design: DSS was administered to animals in drinking water as follows:5%DSS from day 1 to 7, 3%DSS from day 8 to 15, 0% DSS fro
