Objective:To investigate the effect mitochondria signal patway on the apoptosis of MC3T3-E1 induced by hydrogen peroxide. Methods:MC3T3-E1 cells were treated with different doses of hydrogen peroxide. MTT was used to exam the cellinhibition rate. We decected the apoptosis rate, JC-1 the leve of ROS and the expression of Bax in mitochondria. Results:The apoptosis rate and the leve of ROS were increased by hydrogen peroxide, mitochondria membrane potential was deceased. Conclusion:Hydrogen peroxide can induce MC3T3-E1 cellapoptosis through mitochondria signal pathway.
