Activin down-regulates Bcor in TSCs.
A and B, 129R3 mouse TSCs were treated with 25 ng/ml activin A for the indicated time (A) or treated 12 h for the indicated activin A concentrations (B) and then harvested for qRT-PCR analysis. C and D, R1 ESCs (C) and ESC-induced TSC-like cells (D) were treated with 25 ng/ml activin A for 12 h before being harvested for qRT-PCR analysis. shLuc, luciferase shRNA. Data are presented as mean ± S.E. (n = 3; ***, p < 0.001; **, p < 0.01; *, p < 0.05).
