Following birth, the pups were sacrificed on PD1 and PD14, and PSA-NCAM expression and localization in neonates¡¯ hippocampi were analyzed by Western blots and immunohistochemistry.Our data show a significant down regulation of hippocampal PSA-NCAM expression in the offspring of Kind+/Seiz+ (p£¿=£¿0.001) and Kind-/Seiz+ (p£¿=£¿0.001) groups compared to the sham control group. The PSA-NCAM immunoreactivity was markedly decreased in all parts of the hippocampus, especially in the CA3 region, in Kind+/Seiz+ (p£¿=£¿0.007) and Kind-/Seiz+ (p£¿=£¿0.007) group¡¯s newborns on both PD1 and 14.Our findings demonstrate that maternal seizures but not kindling influence the expression of PSA-NCAM in the offspring¡¯s hippocampi, which may be considered as a factor for learning/memory and cognitive impairments reported in children born to epileptic mothers. %K Maternal Seizure %K Polysialylated Neural Cell Adhesion Molecule %K Kindling %K Rat Hippocampus %U http://www.jbiomedsci.com/content/19/1/56/abstract
