Abstract
The purpose of the present study was to determine the role of peroxisome proliferator-activated receptor gamma (PPARgamma) activation in smooth muscle cell (SMC) derived form cell formation. Wild and mutant type PPARgamma were delivered by adenovirus then activated with troglitazone. The result of Oil Red O staining and FACS analysis showed that PPARgamma activation induced lipid accumulation in rVSMCs. Furthermore, PPARgamma activation reduced SMC marker genes such as alpha-actin while induced adipocyte differentiation marker genes and lipid metabolism-related genes as evidenced by RT-PCR and fluorescent immunocytochemistry. All these data demonstrate that PPARgamma activation can drive foam cell like change in rVSMCs. Our results strongly suggest that PPARgamma expression induces CD36 expression and adipocyte differentiation gene activation in the process of atherosclerosis and might be one of the crucial events in SMC derived foam cell formation.Entities:
