Figure 7. Cell death by TGF-β1 or miR-30c-1. (A) Mitochondrial membrane potential was measured by MitoPotential kit. (B–D) Cleaved caspase 9 and cleaved poly ADP ribose polymerase (PARP) levels were evaluated by western blotting and quantified. (E–F) Cleaved caspase 3 was evaluated by western blotting and quantified. *statistically significant.
