ABSTRACT
BACKGROUND: In recent years, with the progress of shock therapy as well as the establishment and promoted application of arterial bypass grafting, thrombolytic therapy, percutaneous transluminal coronary angioplasty, extracorporeal circulation on cardiac surgery, cardiopulmonary resuscitation, limb replantation, and organ transplantation, blood reperfusion in multiple organs after ischemia has been achieved. However, the organs which undergo a period of ischemia appear to have the performance of damage aggravation.OBJECTIVE: To summarize the research progress of MG53 protein in protecting five organs from ischemia/reperfusion injury, thereby providing reference for further in-depth study.METHODS: A computer-based online search of PubMed, Duxiu Knowledge Search and CNKI databases was performed for relevant literatures puldished between 1986 and 2016. The key words were MG53, TRIM, Mitsugumin53, ischemic, reperfusion, preconditioning, postconditioning, RISK, membrane damage, Connexin43, KChIP2 in English and MG53, ischemia/reperfusion in Chinese. Finally 61 eligible articles were reviewed in accordance with the inclusion and exclusion criteria. RESULTS AND CONCLUSION: As a muscle-specific TRIM family protein, endogenous MG53 is involved in the repair of muscle cytomembrane damage, and the protective effects of ischemic preconditioning and postconditioning. Exogenous recombinant human MG 53 protein not only repairs membrane damage of various muscles and non-muscle cells, but also protects the myocardium, skeletal muscle, brain, lung and kidney from ischemia/reperfusion injury.
