Abstract

Using electrophoretic mobility-shift assay (EMSA), were examined DNA- binding activity of cAMP response element (CRE), onto its responsive element CRE, as well as TPA consecutive element (TRE) in the medial hypothalamus and striatum of the experimental rabbits administered with haloperidol under heat stress exposure and studied the effects of dantrolene sodium to the transcriptional factor. In EMSA with nuclear extracts from the rabbit brain, the DNA-binding activities of CRE and TRE in medial hypothalamus and striatum increased following haloperidol and heat stress. These increases were maintained by coadministration with atropine. The treatment with dantrolene sodium markedly reversed such increases. The alterations of activities of these transcriptional factors may reflect the therapeutic effect of dantrolene sodium.
