Protective role and mechanism of peroxysome proliferator activated receptor-? in injury of cultured rat cortical neurons induced by hypoxia/ reoxygenation / 中国病理生理杂志

ABSTRACT

AIM: To observe the role of peroxysome proliferator activated receptor-?(PPAR-?) and the relationship of cyclooxygenase-2(COX-2) and PPAR-? in injury of cultured rat cortical neurons induced by hypoxia/reoxygenation.METHODS: Primary rat cortical neurons were cultured.Experiments include control group,hypoxia/ reoxygenation group and hypoxia/ reoxygenation with PPAR-? agonist group.Cell viability was surveyed by MTT assay.COX-2 protein expression was measured by Western blotting.RESULTS: Neuron viability raised dramatically in hypoxia/reoxygenation with PPAR-? agonist group,compared with hypoxia/reoxygenation group(P
