  sub:_4 prov:value "When PPARg expression was restored with retroviral gene transfer, however, they differentiated well, suggesting that C/EBPa plays an important role in adipogenesis primarily by inducing the expression of PPARg. Ectopic expression of PPARg circumvents the requirement for C/EBPa in adipogenesis, at least with respect to lipid accumulation and most gene expression. Interestingly, C/EBPa -/- adipocytes created by ectopic expression of PPARg are not insulin sensitive, a deficiency that could be restored by re-introducing C/EBPa." ;
