Research Abstract |
We showed that both phosphodiesterase III inhibitors and Rho kinase inhibitors administered just before reperfusion protect against liver ischemia reperfusion injury and apoptosis. This protective effect was attenuated by wortmannin, a PI3K-Akt inhibitor, PD-98059, an ERK inhibitor, or L-NAME, a eNOS inhibitor. Both phosphodiesterase III inhibitors and Rho kinase inhibitors administered just before reperfusion activated PI3K-Akt, ERK, or eNOS. Thus both phosphodiesterase III inhibitors and Rho kinase inhibitors could have postconditioning effects via PI3K-Akt, ERK, or eNOS activation.
