MyoD methylation is relevant in the inhibition of myogenesis by Sharp-1. (A) C2C12 cells overexpressing Sharp-1 were transfected with MyoD and MyoD(K104R). MyoD expression was analyzed by Western blot. (B-D) Control (vector), MyoD, and MyoD(K104R) cells were analyzed for differentiation with anti-MHC antibody (B), myogenic index (C), and troponin T expression by Western blot (D). (E) C3H10T1/2 cells were transfected with MyoD, MyoD(K104R), Myc-Sharp-1, and FLAG-G9a. MyoD was immunoprecipitated and probed with anti-Me Lys antibody. Expression of Sharp-1, MyoD, and G9a was analyzed in lysates. (F) ChIP assays were performed in Sharp-1–overexpressing C2C12 cells transfected with MyoD and MyoD(K104R). H3K9me2 was analyzed by ChIP assays on the myogenin promoter at D2 of differentiation. Error bars indicate mean ± SD.
