Procaine inhibits cyclic AMP-induced steroidogenesis in isolated bovine adrenocortical cells.

چکیده
Effects of procaine on dibutyryl adenosine 3',5'-cyclic monophosphate ((Bu)2cAMP)-, Ca2(+)- or forskolin-induced steroidogenesis were examined in isolated bovine adrenocortical cells. Procaine (less than 1.0 mM) caused a marked suppression of (Bu)2cAMP- or forskolin-induced steroidogenesis in the absence of extracellular Ca2+, but did not affect on Ca2(+)-induced steroidogenesis in the cells. (Bu)2cAMP decreased the cell associated 45Ca2+. However, procaine (300 microM) inhibited this effect of (Bu)2cAMP. These results suggest that procaine may abolish (Bu)2cAMP-induced Ca2+ release from intracellular calcium store(s) and inhibits steroidogenesis.

Steroidogenic action of calcium ions in isolated adrenocortical cells.
The corticotropin-induced increase of total intracellular and receptor-bound cyclic AMP in isolated rat adrenocortical cells was strictly dependent on extracellular Ca(2+). A rise in bound cyclic AMP with rising Ca(2+) concentrations was accompanied by a decrease in free cyclic AMP-receptor sites. A Ca(2+)-transport inhibitor abolished the rise in bound cyclic AMP induced by corticotropin. Thes...
متن کاملMetabolic regulation and relationship of endogenous protein kinase activity and steroidogenesis in isolated adrenocortical carcinoma cells of the rat.
In the adrenocortical carcinoma cell, in contrast to normal isolated adrenal cells, 10 to 50 muunits of ACTH do not raise the level of adenosine cyclic 3':5'-monophosphate (cyclic AMP), protein kinase activity, and steroidogenesis. This indicates a lesion in the tumor adenylate cyclase system. Two-tenths to 10 mM cyclic AMP and guanosine cyclic 3':5'-monophosphate (cyclic GMP) which stimulate s...
متن کاملComparative effects of angiotensin and ACTH on cyclic AMP and steroidogenesis in isolated bovine adrenal cells.
The comparative effects of angiotensin II and adrenocorticotropic hormone (ACTH) on cyclic AMP and steroidogenesis were investigated employing isolated bovine adrenal cells from the zona fasciculata. Like ACTH, angiotensin produced a prompt increase in cyclic AMP which preceded the increase in corticosteroid production. Although this increase in cyclic AMP was small when compared to that induce...
متن کاملCalmidazolium is a potent stimulator of steroidogenesis via mechanisms not involving cyclic AMP, calcium or protein synthesis.
This study reports an unexpected effect of calmidazolium on steroidogenesis. In contrast with previous work, which established that calmidazolium inhibits hormone-stimulated testosterone production in rat Leydig cells, the present study demonstrates that this compound is a potent stimulator of steroidogenesis when added by itself; this stimulation (approx. 10-fold in a 2 h incubation), was obta...
متن کاملInhibition of adrenal cortical steroid formation by procaine is mediated by reduction of the cAMP-induced 3-hydroxy-3-methylglutaryl-coenzyme A reductase messenger ribonucleic acid levels.
Elevated glucocorticoid levels are associated with many diseases, including age-related depression, hypertension, Alzheimer's disease, and acquired immunodeficiency syndrome. Cortisol-lowering agents could provide useful complementary therapy for these disorders. We examined the effect of procaine and procaine in a pharmaceutical formulation on adrenal cortical steroid formation. Procaine inhib...
