Research Abstract

We tried to reveal the neuroprotective mechanisms induced by the electrical stimulation of cerebellar fastigial nucleus (FN) in rats. 1h-FN stimulation decreased, 72h later, the infarct volume by 22%. 1h-FN stimulation increased, 72h later, mRNA level of uncoupling protein 4 (UCP4), a mitochondria protein, to 160% in the brain. Intra-ventricular injection of siRNA decreased the UCP4 mRNA level, and tended to abolish the neuroprotection induced by FN stimulation. Following FN stimulation, up-regulation of UCP4 may be a component of the endogenous neuroprotective mechanisms.
