Despite its significance, the regulation of SREBP1c expression during adipogenesis is not well characterized. We have noted that in several models of adipogenesis, SREBP1c expression closely mimics that of known C/EBPbeta (CCAAT/enhancer-binding protein beta) targets. Inhibition of C/EBP activity during adipogenesis by expressing either the dominant-negative C/EBPbeta LIP (liver-enriched inhibitory protein) isoform, the co-repressor ETO (eight-twenty one/MTG8) or using siRNAs (small interfering RNAs) targeting either C/EBPbeta or C/EBPdelta significantly impaired early SREBP1c induction. Furthermore, ChIP (chromatin immunoprecipitation) assays identified specific sequences in the SREBP1c promoter to which C/EBPbeta and C/EBPdelta bind in intact cells, demonstrating that these factors may directly regulate SREBP1c expression. Using cells in which C/EBPalpha expression is inhibited using shRNA (short hairpin RNA) and ChIP assays we show that C/EBPalpha replaces C/EBPbeta and C/EBPdelta as a regulator of SREBP1c expression in maturing adipocytes. These results provide novel insight into the induction of SREBP1c expression during adipogenesis. Moreover, the findings of the present study identify an important additional mechanism via which the C/EBP transcription factors may control a network of gene expression regulating adipogenesis, lipogenesis and insulin sensitivity."xsd:string |
