Previous studies suggest that dysfunction of neurotransmitter systems is associated with the pathology of autism in humans and the disease model rodents, but the precise mechanism is not known. Rodent offspring exposed prenatally to VPA shows autism-related behavioral abnormalities. The present study examined the effect of prenatal VPA exposure on brain(More)
Rodents exposed prenatally to valproic acid (VPA) show autism-related behavioral abnormalities. We recently found that prenatal VPA exposure causes a reduction of dopaminergic activity in the prefrontal cortex of male, but not female, mice. This suggests that reduced prefrontal dopaminergic activity is associated with behavioral abnormalities in VPA-treated(More)
Valproic acid (VPA) is a multi-target drug and an inhibitor of histone deacetylase (HDAC). We have previously demonstrated that prenatal exposure to VPA at embryonic day 12.5 (E12.5), but not at E14.5, causes autism-like behavioral abnormalities in male mouse offspring. We have also found that prenatal VPA exposure causes transient histone hyperacetylation(More)
Rodents exposed prenatally to valproic acid (VPA) exhibit autism spectrum disorder (ASD)-like behavioral abnormalities. We recently found that prenatal VPA exposure causes hypofunction of the prefrontal dopaminergic system in mice. This suggests that the dopaminergic system may be a potential pharmacological target for treatment of behavioral abnormalities(More)
Previous studies have shown that inhibitors of the Na(+)/Ca(2+) exchanger (NCX) attenuate seizure activity in drug-induced epilepsy models, but the role of NCX in epilepsy is not fully understood. The present study examined the effects of pentylenetetrazole (PTZ)-induced kindling on the mRNA expression of NCX isoforms (NCX1, NCX2 and NCX3) in mouse brain.(More)
