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

Figure 2

Interactions of Twist-1 with PGC-1α but not with NT-PGC-1α. PGC-1α-HA (a) and NT-PGC-1α-HA (b) were co-expressed with Flag-Twist-1 in COS-1 cells. Immunoprecipitates with IgG or anti-Flag antibody were separated by SDS-PAGE and immunoblotted with anti- PGC-1α (a, top panel) or HA antibody (b, top panel). Expression of Flag-Twist-1 was confirmed by probing with anti-Flag antibody (a and b, bottom panels).
