Research advance in role of ROS in cardioprotection offered by preconditioning or postconditioning / 上海交通大学学报（医学版）

ABSTRACT

Reactive oxygen species(ROS)play an important role in the cardiac ischemic and reperfusion injury.However,accumulating evidences have demonstrated that ROS are pivotal components of redox signaling cascade relevant to cardioprotection induced by either preconditioning or postconditioning. In this review,the definition, source and detection methods of ROS are introduced.Besides,the role of ROS in the cardioprotection offered by preconditioning or postconditioning and the effects of either preconditioning or postconditioning on ROS are summarized.
