Importantly, it has been reported that the administration of 0.6% curcumin in the diet prevented the progression of colorectal cancer associated with colitis in C57BL/6 mice by inhibiting the translocation of β-catenin from adherens junction complexes to the cytoplasm and nucleus and reducing the levels of diverse proinflammatory cytokines, inducible nitric oxide synthase (iNOS) and COX-2 as compared to untreated mice (Figure 1) [167]. Here, PTGS2 is linked to colorectal cancer.
