| Notes | Objective To evaluate the mitochondrial function to understand the mitochondria-mediated caspase-9 activation and apoptosis in adult Kashin-Beck disease（KBD） chondrocytes.Methods Apoptotic cell was evaluated by analyzing the apoptosis rate of KBD articular chondrocytes and the caspase-9 and 3 activities.Mitochondrial function was evaluated by analyzing the cytochrome c release from mitochondria to the cytosol and the intracellular reactive oxygen species（ROS） contents.Results The percentage of positive apoptotic chondrocytes from the KBD patient group exhibited a higher level than that of the healthy controls.Mitochondrial cytochrome c release and caspase-9 and 3 activation were also found.Conclusion These findings suggest the involvement of mitochondrial oxidative stress and celluar apoptosis in the pathophysiology of KBD.The dysfunction of mitochondria may play an important role in KBD articular chondrocytes apoptosis.
