Mitochondrial STAT3 activation and cardioprotection by ischemic postconditioning in pigs with regional myocardial ischemia/reperfusion.
RATIONALE Timely restoration of coronary blood flow is the only way to salvage myocardium from infarction, but reperfusion per se brings on additional injury. Such reperfusion injury and the resulting size of myocardial infarction is attenuated by ischemic postconditioning, ie, the repeated brief interruption of coronary blood flow during early reperfusion. The signal transduction of ischemic p...

Rationale: Timely restoration of coronary blood flow is the only way to salvage myocardium from infarction, but reperfusion per se brings on additional injury. Such reperfusion injury and the resulting size of myocardial infarction is attenuated by ischemic postconditioning, ie, the repeated brief interruption of coronary blood flow during early reperfusion. The signal transduction of ischemic ...
متن کاملCardioprotection by ischemic postconditioning is lost in aged and STAT3-deficient mice.
The cardioprotection by ischemic preconditioning is lost in aged wild-type and in STAT3 (signal transducer and activator of transcription 3)-deficient mice. The aim of the present study was to analyze whether or not ischemic postconditioning (iPoco) was effective in aged mice hearts and whether iPoco was dependent on STAT3. Young (3 months) and aged (>13 months) C57Bl6/J mice underwent 30 minut...
متن کاملHyperglycemia Abrogates Ischemic Postconditioning Cardioprotection by Impairing AdipoR1/Caveolin-3/STAT3 Signaling in Diabetic Rats.
Signal transducer and activator of transcription 3 (STAT3) activation is key for ischemic postconditioning (IPo) to attenuate myocardial ischemia-reperfusion injury (MIRI), but IPo loses cardioprotection in diabetes in which cardiac STAT3 activation is impaired and adiponectin (APN) reduced. We found that IPo increased postischemic cardiomyocyte-derived APN, activated mitochondrial STAT3 (mitoS...
متن کاملEndogenous hydrogen sulphide mediates the cardioprotection induced by ischemic postconditioning.
The present study aimed to investigate the role of hydrogen sulphide (H2S) in the cardioprotection induced by ischemic postconditioning and to examine the underlying mechanisms. Cardiodynamics and myocardial infarction were measured in isolated rat hearts. Postconditioning with six episodes of 10-s ischemia (IPostC) significantly improved cardiodynamic function, which was attenuated by the bloc...
