【 摘 要 】

References(18)Cited-By(3)The present study was designed to evaluate whether ethanol suppresses survival-signaling pathways in rat testes. Ethanol (1.5 g/kg or 3 g/kg i.p., 15% v/v in saline) was administrated to adult male rats for 10 days. Ethanol treatment significantly increased the number of TUNEL-positive cells in rat testes. Potential activation was measured by phosphorylation of Akt and Erk1/2 using Western blot analysis. Ethanol decreased the levels of activated survival kinases, pAkt and pErk1/2. The phosphorylation of Bad at Ser112 and Ser136 was decreased in ethanol-treated animals in comparison to saline-treated animals. Moreover, the interaction of pBad with 14-3-3 was decreased by ethanol exposure. In conclusion, our findings suggest that ethanol induces apoptotic cell death by suppressing the activation of survival kinases and the phosphorylation of their downstream targets in rat testes.
