Abstract

Differentiation therapy pursues the discovery of novel molecules to transform cancer progression into less aggressive phenotypes by mechanisms involving enforced cell transdifferentiation. In this study, we examined the identification of transdifferentiating adipogenic programs in human cancer cell lines (HCCLs). Our findings showed that specific unsatturated fatty acids, such as palmitoleic, oleic and linoleic acids, trigger remarkable phenotypic modifications in a large number of human cancer cell lines (HCCLs), including hepatocarcinoma HUH-7, ovarian carcinoma SK-OV-3, breast adenocarcinoma MCF-7 and melanoma MALME-3M. In particular, we characterized a massive biogenesis of lipid droplets (LDs) and up-regulation of the adipogenic master regulator, PPARG, resulting in the transdifferentiation of HCCLs into adipocyte-like cells. These findings suggest the possibility of a novel strategy in cancer differentiation therapy via switching the identity of HCCLs to an adipogenic phenotype through unsaturated fatty acid-induced transdifferentiation.
