Knockdown of Myog decreases expression of late muscle genes in differentiating C2C12 myoblasts. Stable transfected cells were obtained after transfection of pSuper-Myog into C2C12 myoblasts and selection with G418. Total RNAs were extracted from the transfected cells and RT-PCR was performed to estimate the transcripts of Myog, MyoD, Myf5, early genes (Cdh15, Desmin), and late genes (Mhc, Mck, Tncs, Mylf3). GAPDH was used as an internal control. C2-V: C2C12 cells transfected with pSuper empty vector (control); C2-G1, 2 and 3: C2C12 cells transfected with pSuper-Myog.
