β-catenin overexpression abolishes the effect of carbamazepine on adipogenesis. (A) Cells treated with vehicle or 40 μM carbamazepine were differentiated after β-catenin overexpression and stained with Oil Red O. (Top) Photomicrographs of entire wells; (Bottom) Photomicrographs of stained cells (scale bar, 100 μm). (B) PPARγ mRNA levels were analyzed by qRT-PCR (n = 5 per group). (C) Protein levels of Wnt/β-catenin signaling and PPARγ in 3T3-L1 cells overexpressing β-catenin after carbamazepine treatment were analyzed by Western blot. (D) mRNA levels of adipogenic genes in 3T3-L1 cells overexpressing β-catenin after carbamazepine treatment were analyzed by qRT-PCR (n = 5 per group). Values are mean ± SEM. * P < 0.05; ** P < 0.01.
