Transcriptional Activity of PGC-1 and NT-PGC-1 Is Differentially Regulated by Twist-1 in Brown Fat Metabolism

Figure 3

The elevated Twist-1 levels in brown preadipocytes by retroviral infection. Immortalized PGC-1α -deficient brown preadipocyte cells that express pBABE-neo vector, PGC-1α, or NT-PGC-1α were transduced with pBABE-zeo or Twist-1 retrovirus. Zeocine-resistant cells were pooled and Twist-1 expression was assessed by real time-PCR analysis. Relative abundance of Twist-1 mRNA was normalized to that of cyclophilin mRNA.
