A transortin-hydrocortisone complex has been isolated from human serum by affinity chromatography on oxidized corticosterone coupled to AH-Sepharose 4B. The influence of this complex and of hydrocortisone alone on endogenous RNA polymerase activity from thymus chromatin have been tested. Results show that hydrocortisone alone has no effect on RNA polymerase activity from thymus chromatin. Under the same experimental conditions, The transcortin-hydrocortisone complex induces an important decrease in the incorporation of UMP into RNA. The dose response of thymic RNA polymerase to transcortin-hydrocortisone complex and the effects of alpha-amanitin on this response are also reported. 相似文献
