The objective of this study was to fucus on gene expression levels of (KRT-14; associated with epithelial cell integrity) and enhancer of zeste homolog-1 (EZH-2; involved in cellular proliferation) in a IBD rat model in order to rule out impact of nutraceuticals (pumpkin seed oil; PSO) as a complementary approach to conventional treatments of IBD. This evidence concerns the gene EZH1 and inflammatory bowel disease.
