Ischemic preconditioning activates MAPKAPK2 in the isolated rabbit heart: evidence for involvement of p38 MAPK.
Recent studies suggest that p38 mitogen-activated protein kinase (MAPK) may be involved in ischemic preconditioning (PC). To further test this possibility, the regulation of MAPK-activated protein kinase 2 (MAPKAPK2), a kinase immediately downstream from p38 MAPK, and the activity of c-Jun NH(2)-terminal kinase (JNK), a second MAPK, were examined in preconditioned hearts. Isolated, perfused rab...
متن کاملPreconditioning reduces tissue complement gene expression in the rabbit isolated heart.
Both preconditioning and inhibition of complement activation have been shown to ameliorate myocardial ischemia-reperfusion injury. The recent demonstration that myocardial tissue expresses complement components led us to investigate whether preconditioning affects complement expression in the isolated heart. Hearts from New Zealand White rabbits were exposed to either two rounds of 5 min global...
متن کاملMetabolism in Isolated Rabbit Heart
To investigate whether energy derived from glycolytic and oxidative metabolism are preferentially used for different functions in heart, tension, intracellular potential, and extracellular [K+] and pH (using triple barrel K/pH electrodes, tip diameter 0.5 mm) were monitored in isolated arterially perfused rabbit interventricular septa during exposure to hypoxia and metabolic inhibitors. Myocard...
متن کاملBradykinin mediates cardiac preconditioning at a distance.
Preconditioning the heart by brief coronary (CAO) or mesenteric artery occlusion (MAO) can protect against damage during subsequent prolonged CAO and reperfusion. The role of bradykinin (BK) in remote cardiac preconditioning by MAO is investigated by antagonizing the BK B(2) receptor [Hoechst 140 (HOE-140)] or simulating local BK release by mesenteric intra-arterial infusion. Anesthetized male ...
متن کاملischaemic preconditioning in isolated rat heart
Objective: To assess whether the protective effect of ischaemic preconditioning (IPC) on endothelial function in coronary arteries of the rat involves prostaglandins. Methods: Isolated rat hearts perfused under constant flow conditions were exposed to 30 min of partial ischaemia (flow-rate 1 ml /min) followed by 20 min of reperfusion, after which coronaries were precontracted with U-46619 0.1 m...
