Effect of metformin on apoptosis.
A, Western blot analysis of PARP1 in USPC-2 and USPC-1 cells. B, Western blot analysis of caspase 9 in USPC-2 and USPC-1 cells. C, Western blot analysis of caspase 3 in USPC-2 cells. Cells were treated with metformin for 24 h in the presence or absence of IGF-I. Whole-cell lysates (100 µg) were resolved by SDS-PAGE and immunoblotted with the indicated antibodies. Results are representative of three independent experiments.
