METHODS: The presence of apoptosis was detected by electron microscope and flow cytometry assessment of PI/Annexin V stain; The protein levels of Bax, Bel-2 and activation of caspase-3 were examined using Western blot technique. RESULTS: After treatment with 30 &mgr;mol/L simvastatin for 24 h, apoptosis were identified with electron microscope in VSMC and flow cytometry showed that rate of apoptosis in simvastatin group (35.5+/-5.8)% was singificantly higher than that in control group (15.1+/-5.0)%. Western blot analyses revealed that the apoptosis process was associated with upregulation of Bax protein and activation of caspase-3, but not with Bel-2 expression. CONCLUSION: Simvastatin can induce apoptosis in VSMC in associated with induction of bax and activation of caspase-3.Read More
