Effects of maternal obesity on mRNA expression of EphA4, ephrin-A3, PSD-95 and synaptophysin in the hippocampus and PFC of offspring: EphA4 and PSD-95 mRNA expressions significantly decreased in the hippocampus of offspring of obese dams (A, C); there was no difference in the hippocampal ephrin-A3 and synaptophysin mRNA levels between the groups (B, D); a significant correlation between EphA4 and PSD-95 mRNA expressions in the hippocampus was observed (E); there was no difference in the ephrin-A3, EphA4, PSD-95 and synaptophysin mRNA levels in the PFC between the groups (F–I). *p < 0.05, **p < 0.01, (n = 7/control group; n = 6/ obese group)
