ABSTRACT
Objective To explore the effect of Tanshinone IIA on apoptosis and expression of Drp-1 and TRPM7 in a rat model of focal cerebral ischemia and reperfusion. Methods Rats were pretreated with high or low dose of tanshinone IIA before 2 h-focal cerebral ischemia plus 24 h-reperfusion. Cerebral blood flow in the middle cerebral artery was moni-tored during reperfusion. TTC, TUNEL and western blotting were used to detect the volume of cerebral infarction, apopto-sis and the protein expression of Drp-1 as well as TRPM7, respectively. Results Compared with control group, pretreat-ment with Tanshinone IIA could significantly down-regulate the expression of protein Drp-1 and TRPM7 (P0.05). Conclusions Tanshinone IIA can inhibit ischemia-induced neuronal apoptosis and mitochondrial fission probably through improving cerebral artery blood flow and reducing the overexpression of Drp-1,TRPM7.
