Resveratrol regulates neuronal cell apoptosis by regulating the TGF-β-mediated ERK signaling pathway. Effects of resveratrol on TGF-β and ERK (A) mRNA and (B) protein expression in neurons isolated from rats with cerebral hemorrhage. Effect of TGF-β inhibitor on the TGF-β and ERK (C) mRNA and (D) protein levels. (E) Effects of treatment with TGF-β on resveratrol-decreased ERK and pERK expression in neurons. (F) Effects of treatment with TGF-β on neuronal apoptosis. **P<0.01. TGF-β, transforming growth factor-β; ERK, extracellular signal-regulated kinase; TGF-βIR, TGF-β inhibitor; ns, not significant.
