Melatonin potentiates the antitumor effect of curcumin by

promoter via inhibiting IKKβ activity resulting in inhibition of COX-2 expression In addition combined treatment with curcumin and melatonin induced cell apoptosis in bladder cancer through enhancing the release of cytochrome from c the mitochondrial intermembrane space into the cytosol These results therefore indicated that melatonin synergized the inhibitory effect of curcumin against

Gene modulation by Cox

Many studies on the chemo-preventative activity of Cox inhibitors used classical NSAIDs that inhibit both Cox-1 and Cox-2 However classical Cox inhibitors such as sulindac sulfide and indomethacin are more potent inhibitors of Cox-1 than Cox-2 Recently a concerted effort has been focused on the Cox-2 specific inhibitors since Cox-2 is highly expressed in tumor tissues [for a review see ref
