Sevoflurane Postconditioning Reduces Apoptosis by Activating the JAK-STAT Pathway After Transient Global Cerebral Ischemia in Rats.
The antiapoptotic effects of sevoflurane postconditioning are responsible for neuroprotection against cerebral ischemia-reperfusion injury. Phosphorylation of the Janus family tyrosine kinases (JAK) 2-signal transducers and activators of transcription (STAT) 3 pathway is linked to antiapoptosis. Here, we determined whether the antiapoptotic effects of sevoflurane postconditioning are associated with activation of the JAK2-STAT3 pathway after global transient cerebral ischemia in rats. ⋯ Sevoflurane postconditioning reduced apoptosis by increasing P-JAK and P-STAT expression after transient global ischemia in rats, and AG490 reversed the beneficial antiapoptotic effects of sevoflurane postconditioning, suggesting that the JAK-STAT pathway may be involved in the antiapoptotic mechanism of sevoflurane postconditioning.
