Abstract: Compositions for and methods of treating irritable bowel disease are provided. The compositions and methods employ MG53, which can be in the form of recombinant human MG53. The MG53 can be administered in a form to avoid or bypass gastric digestion or degradation. The composition can include a live MG53-expressing microbe, such as a probiotic composition that expresses MG53 in the gastrointestinal tract of a subject. An enteric release composition comprising MG53 is also provided.

Abstract: Compositions for and methods of treating liver injury are provided. Said compositions comprise MG53 or express MG53. Said compositions can be used for treating chronic or acute injured liver tissue and can be administered systemically, locally, or both.

Abstract: The invention discloses application of irisin in the preparation of drugs for preventing myocardial ischemia reperfusion injuries. Experimental results show that irisin can decrease the myocardial infarction area caused by ischemia reperfusion, reduce the increase of the contents of lactate dehydrogenase (LDH), troponin (cTnI), creatine kinase (CK), and other myocardial enzyme markers caused by ischemia reperfusion, meanwhile reducing the inflammatory response, myocardial apoptosis, and oxidative stress response caused by myocardial ischemia reperfusion, promote peroxysome proliferator-activated receptor ? nuclear translocation, and inhibit nuclear transcription factor NF-?B nuclear translocation and accordingly decrease myocardial structure injuries and load increase caused by ischemia reperfusion. Therefore, irisin can be used for preventing and decreasing myocardial reperfusion injuries and has important clinical significance on the treatment of myocardial ischemia.
