Cardiac Akt, endothelial nitric oxide synthase (eNOS), and neuronal nitric oxide synthase (nNOS) proteins were determined by Western blot analysis.

Isoflurane decreased infarct size from 54 ± 10% in control to 36 ± 10% (<jats:italic toggle="yes">P</jats:italic>< 0.05, n = 8 mice per group), improved cardiac function after reperfusion, and increased the ratios of phosphorylated-Akt/AKT, phosphorylated-eNOS/eNOS, and phosphorylated-nNOS/nNOS in C57BL/6 mice subjected to ischemia–reperfusion injury. These beneficial effects of isoflurane were lost in microRNA-21 knockout mice. There were no significant differences in time of the mPTP opening induced by photoexcitation-generated oxidative stress in cardiomyocytes isolated between C57BL/6 and microRNA-21 knockout mice. Isoflurane significantly delayed mPTP opening in cardiomyocytes from C57BL/6 but not from microRNA-21 knockout mice.</jats:p></jats:sec><jats:sec><jats:title>Conclusions:</jats:title><jats:p>Isoflurane protects mouse hearts from ischemia–reperfusion injury by a microRNA-21-dependent mechanism.
