FIG. 8.

Induction of ETR-3 protein expression and cTNT exon inclusion occur simultaneously during skeletal muscle differentiation. (A) ETR-3 Western blot of total protein extracts from C2C12 murine myoblast cells induced to differentiate. Fifty micrograms of total protein was loaded in each lane. (B) RT-PCR analysis of cTNT minigene RNA from similar cultures transfected with R35C harvested over the same time course. Loading was adjusted so that approximately equal counts were loaded in each lane.
