Based on our observations of energy sparing in heat-acclimated (AC) rat hearts, we investigated whether changes in preischemic glycogen level, glycolytic rate, and plasma thyroxine level mediate cardioprotection induced in these hearts during ischemia-reperfusion insults. Control (C) (24 degrees C), AC (34 degrees C, 30 days), acclimated-euthyroid (34 degrees C + 3 ng/ml l-thyroxine), and contr...
Activation of myocardial A1 adenosine receptors (A1AR) protects the heart from ischemic injury. In this study transgenic mice were created using the cardiac-specific alpha-myosin heavy chain promoter and rat A1AR cDNA. Heart membranes from two transgene positive lines displayed approximately 1,000-fold overexpression of A1AR (6,574 +/- 965 and 10,691 +/- 1,002 fmol per mg of protein vs. 8 +/- 5...
Because the question "is AMP-activated protein kinase (AMPK) alpha(2)-isoform a friend or a foe in the protection of the myocardium against ischemia-reperfusion injury?" is still in debate, we studied the functional consequence of its deletion on the contractility, the energetics, and the respiration of the isolated perfused heart and characterized the response to low-flow ischemia and reperfus...
The purpose of this study was to compare the degree of ischemic and hypoxic injury in normal versus hypertrophied rat hearts to investigate basic mechanisms responsible for irreversible myocardial ischemic injury. Hearts from rats with bands placed on the aortic arch at 23 days of age (BAND) and sham-operated rats (SHAM, 8 weeks postoperative) were isolated, perfused with Krebs buffer, and had ...
