This study evaluated the anti-tumor efficacy of combining the RXR agonist, bexarotene, with the PPARγ agonist, rosiglitazone, in colon cancer. Moser, a human colon cancer cell line, was treated with bexarotene and rosiglitazone alone or in combination and the effect on growth and differentiation were examined. The data demonstrated that the bexarotene/rosiglitazone combination produced greater efficacy in growth inhibition than either single agent. Furthermore, combination treatment acted cooperatively to decrease COX-2 expression and PGE2 synthesis while increasing expression of the differentiation marker, CEA. These findings were confirmed in vivo in a Moser xenograft tumor model. Collectively, our data suggest a potential role for utilizing a combination regimen of a RXR and PPARγ agonist in the treatment of colon cancer.
