WEN Quan-qing, et al. Expression analysis of microRNA on acute cerebral ischemia in rats[J]. Journal of Chongqing Medical University, 2008,(S1):23-26.DOI:
Objective:To observe the change of microRNA(miRNA) expression on acute cerebral ischemia in rats. Methods:We adopted the permanent occlusion of bilateral common carotid arteries in Wistar rats to produce cerebral ischemia model (2VO).Then we examined miRNA expression of cortex tissue after 60 minutes of occlusion by miRNA chip. Results:Compared with normal rats
35 pieces of miRNA were up-regulated more than twice in the 2VO rats.And 89 pieces were down-regulated more than twice. Conclusion:The miRNA changed on acute cerebral ischemia in rats. It may play an important role in pathophysiology on acute cerebral ischemia.
