Decreased levels of VEGF, COX-2, and PGE2 have been demonstrated in HT-29 colon cancer cell lines when cultured in vitro with EPA and DHA [112] and a synergistic inhibitory effect of n-3 PUFAs and COX-2 inhibitors on growth of human colon cancer cell lines has been shown [60, 132]. Here, VEGFA is linked to colonic neoplasm.
