Effect of neonatal DEX treatment on the expression of glutamate uptake transporter mRNAs in the frontal cortex. (A-C) Quantitative real-time PCR analysis showing the relative expression levels of GLT-1 (A), GLAST (B), and EAAC1 (C) mRNA in the frontal cortex from SAL-, DEX-, vehicle (Veh)- and DEX + RU 38486 (RU)-treated groups on P7. The vehicle group received equivalent volume of intraperitoneal injection of propylene glycol. The numbers in parentheses indicate the number of animals examined. Data are presented as means ± S.E.M. *P < 0.05 compared with SAL-treated group.
