Cardioprotective Effect of the SDF-1α/CXCR4 Axis in Ischemic Postconditioning in Isolated Rat Hearts
BACKGROUND AND OBJECTIVES Information about the role of the stromal cell-derived factor-1α (SDF-1α)/chemokine receptor type 4 (CXCR4) axis in ischemic postconditioning (IPOC) is currently limited. We hypothesized that the SDF-1α/CXCR4 signaling pathway is directly involved in the cardioprotective effect of IPOC. METHODS Isolated rat hearts were divided into four groups. The control group was ...
متن کاملLovastatin interferes with the infarct size-limiting effect of ischemic preconditioning and postconditioning in rat hearts.
Statins have been shown to be cardioprotective; however, their interaction with endogenous cardioprotection by ischemic preconditioning and postconditioning is not known. In the present study, we examined if acute and chronic administration of the 3-hydroxy-3-methylglutaryl CoA reductase inhibitor lovastatin affected the infarct size-limiting effect of ischemic preconditioning and postcondition...
متن کاملRemote limb ischemic postconditioning protects against neonatal hypoxic-ischemic brain injury in rat pups by the opioid receptor/Akt pathway.
BACKGROUND AND PURPOSE Remote ischemic postconditoning, a phenomenon in which brief ischemic stimuli of 1 organ protect another organ against an ischemic insult, has been demonstrated to protect the myocardium and adult brain in animal models. However, mediators of the protection and underlying mechanisms remain to be elucidated. In the present study, we tested the hypothesis that remote limb i...
متن کاملEffects of ischemic postconditioning on left ventricular function of isolated rat hearts.
OBJECTIVE To assess the effects of ischemic postconditioning on left ventricular function in isolated rat hearts. METHODS Twenty-four Wistar rats were used. These hearts underwent perfusion by modified LANGERDORFF method and distributed into three groups: GI--control (n=8); GII--three cycles of postconditioning of 10/10s (n=8); GIII three cycles of postconditioning of 30/30s (n=8). After a 15...
متن کاملIschemic postconditioning influences electron transport chain protein turnover in Langendorff-perfused rat hearts
Ischemia postconditioning (IPo) is a promising strategy in reducing myocardial ischemia reperfusion (I/R) injury (MIRI), but its specific molecular mechanism is incompletely understood. Langendorff-perfused isolated rat hearts were subjected to global I/R and received IPo in the absence or presence of the mitochondrial ATP-sensitive potassium channel (mitoKATP) blocker 5-hydroxydecanoate (5-HD)...
