Abstract
We sought to investigate the role of fibroblast growth factor (FGF)-1 during acute myocardial ischemia and reperfusion. The FGFs display cardioprotective effects during ischemia and reperfusion. We investigated FGF-1-induced cardioprotection during ischemia and reperfusion and the intracellular signaling pathways responsible for these effects in an ex vivo murine setup of myocardial ischemia and reperfusion. Cardiac-specific human FGF-1 overexpression was associated with enhanced post-ischemic hemodynamic recovery and decreased lactate dehydrogenase release during reperfusion. Inhibition of the FGF receptor, protein kinase C (PKC), and tyrosine kinase (TK) resulted in blockade of FGF-1-induced protective effects on cardiac functional recovery and cell death. The overexpression of FGF-1 induces cardioprotection through a pathway that involves the FGF receptor, PKC, and TK
