A kinetic study of bioactive anthocyanins and their biological activity for colorectal chemoprevention and immunization was also conducted by determining their inhibition effect on nitric oxide (NO), inducible nitric oxide synthase (iNOS), and COX-2 in interferon-γ (IFN-γ)-stimulated colon adenocarcinoma (HT-29) cells. This evidence concerns the gene PTGS2 and colon adenocarcinoma.
