摘要
The connexin 43 （ Cx43 ） proteins, which is the predominant protein that can form gap junctions and non- junctional hemichannels in ventricular myocardium, are central to the cardioprotection afforded by ischemic preconditioning （IP） and maybe ischemic postconditioning （ PC ） too. Recent studies showed that recruitment of Cx43 to the mitochondria in IP might play a role in the production of reactive oxygen species （ROS） that mediates IP. The localization of Cx43 at mitochondria appears to be important for the achieved cardioprotection and opens a new door for us to reveal the exact mechanisms of ischemia/reperfusion （I/R） injury and cardioprotection, and it might be new targets of pharmacological modulator to achieved cardioprotection.
