It is known that fatty acids derived from endogenous metabolism or nutrition can act as second messengers and regulators of cell signaling pathways. The peroxisome proliferator-activated receptors (PPARs) belong to the steroid hormone superfamily. The PPARs are activated by fatty acids and fatty acid-like chemicals called peroxisome proliferators (PPs). The activation of the PPARs affects several cell functions such as cell proliferation and differentiation, and modulates the expression of different target-genes. This is a review of the current literature regarding the potential role of PPARs in mediating the effects of fatty acids on gene expression, cell growth, differentiation and apoptosis.

Key words: Cancer, Fatty acids, Peroxisome proliferators, PPAR.
