Western blotting analysis of phospho-GSK-3β at Ser9 and total GSK-3β protein in isolated rat hearts. Myocardial samples were collected from the risk zone at 5 (R5′) and 10 (R10′) min after the onset of reperfusion. Resveratrol (10 μM, n = 6) significantly enhanced GSK-3β phosphorylation at reperfusion compared to control (n = 6). *, P<0.05 versus control (t-test).
