CYCS and ischemia: Compared with the control group, the expression of caspases-3 and -9, Fas, Fas-L, and the mitochondrial release of cytochrome c were significantly increased in the ischemia/reperfusion group (P < 0.01), and bromocriptine reversed these increases (P < 0.05 or P < 0.01 versus ischemia/reperfusion group).
