In order to evaluate the involvement of the stimulatory G-protein (Gs)-related transduction system in the basic mechanisms of epilepsy, we examine the expression levels of Gsalpha mRNA and specific GTP-binding ability in the hippocampus of amygdaloid-kindled rats at various seizure stages. Northern blot analysis showed a significant increase in the Gsalpha(More)
The expressions of mRNAs encoding G protein alpha subunits were analyzed in the cerebral cortex of amygdaloid kindled rats. A remarkable increase in Gsalpha mRNA were observed on the bilateral cerebral cortex at 24 h after the last generalized seizure and persisted 3 weeks on the unstimulated side. Gi2alpha mRNA level was also increased on the stimulated(More)
The expression level of type II adenylyl cyclase mRNA (ACII) was analyzed by northern blotting in amygdaloid kindled rats. Remarkable increases in ACII mRNA were observed in the bilateral cerebral cortex and hippocampus at 24 h after the last generalized seizure. The elevated expression level in the hippocampus persisted for 4 weeks on the stimulated side.(More)
