Expression of Ogg1 and Pol γ at mRNA and protein levels during epileptogenesis. To assess the induction of the BER pathway during epileptogenesis, the levels of both Ogg1 and Pol γ at an mRNA and protein level were monitored as described in Materials and Methods. A) mRNA expression at the indicated time points was determined by real-time PCR performed on a primer/probe set specific to Ogg1 and Pol γ. B) Protein expression of Ogg1 and Pol γ at the indicated time points was determined via immunoblot analysis. C and D) Immunoblots of Ogg1 and Pol γ, respectively from hippocampal tissue after kainate treatment. Lane 1, CON; lane 2, 24h; lane 3; Lane 4, 48h; Lane 5, 96h; Lane 6, 7d; Lane 7, 21d; Lane 8, 3m. Bars represent mean ± SEM. **P<0.01, vs. saline treated controls, one way ANOVA, n= 3–5 per group.
