PPARG and cancer: Incontradiction to data suggesting that activation of PPARγ can reduce tumor growth, treatment with PPARγ ligands increased the number of colon tumorsin the Min mouse model offamilialadenomatous polyposis [71, 72].In this model, PPARγ may be playing a role in tumor promotion.Thus, it appears thatactivation or inhibition of PPARγ can have dual roles in tumorigenesis dependingon the type of cancer models examined.
