Gene Expression in Rats Fed a Western Diet

ABSTRACT: Resistant starches (RS), fed as high amylose maize starch (HAMS) or butyrylated HAMS (HAMSB), oppose dietary protein-induced colonocyte DNA damage in rats. In this study, rats were fed diets high in fat (19%) and protein (20%) with different forms of digestible starch (low amylose maize starch (LAMS) or low amylose whole wheat (LAW)) or RS (HAMS, HAMSB, or a whole high amylose wheat (HAW) generated by RNA interference (RNAi)) for 11 wk. A control diet contained 7% fat, 13% protein and LAMS. The aim of this study was to detect changes in the expression of DNA damage and repair genes in response to the above dietary treatments. Distal colon tissues from Sprague Dawley rats fed a variety of diets (see summary) were removed from RNAlater stabilisation reagent (Sigma, Australia) they had be
