Electroconvulsive shock increases preproenkephalin messenger RNA abundance in rat hypothalamus.

Daily administration of electroconvulsive shock (ECS) to rats for 10 days increased the content of [Met5]enkephalin in the hypothalamus and the striatum by 64% and 45%, respectively. The effect of ECS on the relative abundance of mRNA coding for the enkephalin precursor preproenkephalin was investigated. Analysis by cell-free translation of polyadenylylated RNA and immunoprecipitation of prepro...

GABAergic regulation of enkephalin in rat striatum: alterations in Met5-enkephalin level, precursor content and preproenkephalin messenger RNA abundance.

The influence of chronic activation of gamma-aminobutyric acid (GABA) system on Met5-enkephalin (ME) biosynthesis was investigated in male rats. Activation of GABA system was achieved by raising the brain GABA concentration with aminooxyacetic acid (AOAA) or gabaculine which inhibits GABA-transaminase the enzyme responsible for the catabolism of GABA. After a regimen of repeated administration ...

Repeated Electroconvulsive Shock Produces Long-lasting Increases

Electroconvulsive shock (ECS) is a highly effective therapy for the treatment of major depression, but its mechanisms of action are not known. We report that repeated ECS in rats produces enduring changes in two clinically relevant stress-responsive brain systems: (a) the hypothalamic-pituitary-adrenal axis regulated by corticotropin-releasing hormone (CRH) in the paraventricular nucleus; and (...

Denervation of rat adrenal glands markedly increases preproenkephalin mRNA.

The effect of denervation on the expression of rat adrenal proenkephalin has been examined. Following splanchnicectomy there was a several-fold increase in the steady-state levels of preproenkephalin mRNA, which became maximal after 24-48 hr (greater than 10-fold). These results indicate that the previously observed increase in rat adrenal enkephalin-containing peptides following denervation oc...

Electroconvulsive shock raises prostaglandins F in rat cerebral cortex.

'101 The prostaglandins are potent autacoids which are widely distributed in mammalian tissues [I] including the central nervous system of various species [2-43. Although tissue stores are quite small, prostaglandins (PG's) are rapidly synthesized and released in association with peripheral nerve stimulation [S]. Several groups of workers have reported that PG's and PG-like substances are relea...
