Representative PCR and western blot show the hippocampus of the control group (KA-, RG108-), KA-treated(SE) group (KA+, RG108-) and RG108-pretreated (RG) group prior to KA (KA+, RG108+). (A, D) A representative PCR and western blot show RASgrf1 mRNA and protein expression in the hippocampus of the control group (lane 1), SE group (lanes 3, 5 and 7) and RG group (lanes 2, 4 and 6) at different time points. (B, E) Quantitative analyses show that the mRNA and protein expression of RASgrf1 decreased gradually after the onset of epileptic seizures and that a significant difference appeared on the 45th day. *P < 0.05, compared with the control group. (C, F) Pretreatment with RG108 reversed the decrease in RASgrf1 mRNA and protein expression, as shown 45 days after the onset of epileptic seizures, #P < 0.05 (each group n = 5).
