Antagonistic effects of CRTC3 on PRDM16-mediated brown preadipocyte differentiation. (A, Left) Oil Red O staining of cells from the brown stromal vascular fraction (bSVFs) of BKO versus WT (CRTC3 fl/fl) littermates following exposure to differentiation mixture for 7 d. (A, Right) Oil Red O staining of bSVFs from CRTC3 Tg and WT littermates following exposure to differentiation mixture. (B and C) Relative protein (B) and mRNA (C) amounts for thermogenic and myogenic genes in differentiated bSVFs from BKO and WT littermates. (D) Oil Red O and BODIPY staining of C2C12 cells stably expressing PRDM16 after exposure to differentiation mixture for 7 d. Effect of lentiviral CRTC3 overexpression on differentiation of C2C12-PRDM16 cells relative to GFP control shown. (E) Effect of modest CRTC3 overexpression on protein (Left) and mRNA (Right) amounts for thermogenic and myogenic genes in differentiated C2C12-PRDM16 cells. Data in C and E represent means ± SD (*P < 0.05; **P < 0.01).
