The influence of 17-beta-estradiol 17-beta-acetate on adenylyl cyclase activity and aminoacyl-tRNA synthetase phosphatase activity in ovariectomized NMRI mice.

Adenylyl cyclase activity in the uterus of ovariectomized NMRI mice showed an increase of 87% four minutes after intraperitoneal administration of 17-beta-estradiol 17-beta-acetate in water solution, while in the liver of the same animals activity had decreased by 57%. At the same time, the activity of the 51 kDa form of the aminoacyl-tRNA synthetase phosphatase in the uterus showed an increase of 400%, while in the liver a decrease of 60% was observed. Sixty minutes after hormone injection the adenylyl cyclase activities showed no difference from controls.
