Abstract

Histone acetylation in the kidney of the adrenalectomized rat was increased 5 min after a physiological dose of aldosterone. The increase was exclusively in the histone F2a1. The increase in histone acetylation was given by 9alpha-fluorocortisol, deoxycorticosterone and cortisol, but not by progesterone. The increase in histone acetylation was abolished by prior treatment of the animals with the anti-mineralocorticoid agent, SC14266 [potassium 3-(3-oxo-17beta-hydroxy-4,6-androstadien-17-yl) propionate]; the basal degree of histone acetylation was unaffected. Pretreatment of the animals with actinomycin D or cyclo-heximide did not affect the stimulation, showing the stimulation was not due to increased synthesis of enzyme.

摘要

生理剂量的醛固酮作用5分钟后,肾上腺切除大鼠肾脏中的组蛋白乙酰化增加。这种增加仅发生在组蛋白F2a1中。9α-氟皮质醇、脱氧皮质酮和皮质醇可使组蛋白乙酰化增加,但孕酮则不能。用抗盐皮质激素药物SC14266[3-(3-氧代-17β-羟基-4,6-雄甾二烯-17-基)丙酸酯钾]预先处理动物后,组蛋白乙酰化的增加被消除;组蛋白乙酰化的基础水平未受影响。用放线菌素D或环己酰亚胺预先处理动物不影响这种刺激作用,表明这种刺激不是由于酶合成增加所致。
