PPARG and cancer: Specifically,2-cyano-3,12-dioxooleana-1,9-dien-28-oicacid (CDDO), a synthetic triterpenoid, which was shown to activate PPARγ and inducegrowth arrest and apoptosis in treatedbreast cancer cells[103]; also, glycyrrhizinthe major triterpene gycoside phytochemical in licorice root and thetriterpenoid acid betulinic acid which is found in the bark of several speciesof plants, both have shown pro-PPARγ activities incancer cells.
