Metformin protects against myocardial ischemia-reperfusion injury and cell pyroptosis via AMPK/NLRP3 inflammasome pathway
Figure 1. Metformin ameliorated IR-induced cardiac tissue damage in a rat I/R injury model. (A) Representative images of myocardial infarct size stained by TTC staining. (B) Myocardial infarct volumes presented as percentage of infarct area/area at risk (n = 6–8 per group). (C) Mean levels of lactate dehydrogenase (LDH) in all groups (n = 6 per group). (D) Mean levels of creatine kinase-MB (CK-MB) in all groups (n = 6 per group). (E) Mean levels of cardiac troponin I (cTnI) in all groups (n = 6 per group). Values are expressed as the mean ± SEM. * P < 0.05 vs. Sham. # P < 0.05 vs. I/R. & P < 0.05 vs. MET.
