Role of glycolytic flux in effect of glucose in decreasing fatty-acid-induced release of lactate dehydrogenase from isolated coronary ligated rat heart

Abstract

The mechanisms whereby glucose reduces fatty acid-induced release of enzyme from the coronary-ligated isolated perfused working rat heart are investigated. Alterations in the tissue contents of ATP, phosphocreatine, or glycogen could be excluded as possible mechanisms for the beneficial effect of glucose in this system. Provision of glycolytic ATP from increased glycolytic flux may be one important factor.
