The effects of pioglitazone on the expression of ICAM-1 mRNA in the ischemia-reperfusion brain tissues in SD rats / 中华行为医学与脑科学杂志

ABSTRACT

Objective To study the effects of peroxisome prolifterator-activated receptor gamma (PPARγ) agonist on the expression of ICAM-1 mRNA in the ischemia-reperfusion brain tissues. Methods Adult male SD rats were randomly divided into sham-operation + normal saline group (NS,n = 6 ), ischemia-reperfusion tion. The expression of ICAM-1mRNA was measured by RT-PCR at 24 h after ischemia. Results The expression of ICAM-1 mRNA of the low-dose PGZ group (0.571±0.032) and the high-dose PGZ group (0. 396±0.024)were significantly reduced compared with that of the I/R + NS group (0.847±0. 028 ) (P<0.05).Conclusion PPARγ agonists can downregulate the the expression of ICAM-1mRNA in the ischemia brain tissue.
