Desflurane Preconditioning Induces Time-dependent Activation of Protein Kinase C Epsilon and Extracellular Signal-regulated Kinase 1 and 2 in the Rat Heart In Vivo

Abstract

Both, PKC and ERK1/2 mediate desflurane-induced preconditioning. PKC-epsilon and ERK1/2 are both activated in a time dependent manner during desflurane-induced preconditioning, but ERK1/2 activation during desflurane-induced preconditioning is not PKC dependent. Moreover, ERK1/2 blockade abolished PKC-epsilon activation, suggesting ERK-dependent activation of PKC-epsilon during desflurane-induced preconditioning.
