From: Epithelial response to a high-protein diet in rat colon
a Relative expression values of a selection of significantly differentially expressed genes (q < 0.01) participating to the enriched pathway Cell death in the colonocytes of rats fed a high-protein diet (HPD) when compared to a normal-protein diet (NPD). The expression values were obtained by microarray experiment and normalized to the mean value in the NPD group. Bax (BCL2 associated X, apoptosis regulator), Ripk1 (receptor interacting serine/threonine kinase 1), Ilk (integrin linked kinase). b The expression of the apoptotic marker activated caspase 3 protein was quantified by western blot in colonocytes of rats fed an HPD or an NPD. Band intensity was quantified and normalized to the intensity of the band corresponding to actin. For each protein, mean values were compared with a t test. a-b Data presented on histograms are means +/- S.E.M
