Dexmedetomidine attenuates neuronal injury induced by cerebral ischemia‑reperfusion by regulating miR‑199a.

As is well known, dexmedetomidine (DEX) serves a neuroprotective role in cerebral ischemia‑reperfusion (CIR) injury, and microRNA (miR)‑199a has been re‑ported to be associated with IR injury. However, the association between DEX and miR‑199a in CIR injury remains unknown. Thus, the aim of the present study was to verify whether the neuroprotective effect of DEX on cerebral ischemia‑reperfusion rats is associated with miR‑199a.
