As lethality of PPARgamma ( / ) and RXRalpha ( / ) mouse fetuses precluded the analysis of PPARgamma and RXRalpha functions in mature adipocytes , we generated RXRalpha ( ad / ) and PPARgamma ( ad / ) mice , in which RXRalpha and PPARgamma are selectively ablated in adult adipocytes , respectively . ^^^ However , mature adipocytes lacking either both RXRalpha and RXRgamma or PPARgamma die , and are replaced by newly formed adipocytes . ^^^ Thus , in adipocytes , RXRalpha is essential for lipogenesis , but RXRgamma can functionally replace RXRalpha for the adipocyte vital functions exerted by PPARgamma / RXR heterodimers . . ^^^
