[Role of cyclic nucleotide phosphodiesterase in the effect of estradiol on uterine tissue]. 1982

M N Garnovskaia, and I L Dumler, and R N Etingof

It is shown that 17 beta-estradiol (10(-7)--10(-5) M) inhibited phosphodiesterase activity of the preparations (supernatant 100000 epsilon, 1 h) obtained from uterine tissue of sexually mature rats and did not affect adenylate cyclase activity of crude membrane fraction of this tissue. The hormone did not change phosphodiesterase activity of the preparations obtained from the brain, heart and outer segments of the retinal rods. Cytosol preparations from uterine tissue were demonstrated to be able to specific hormone binding. The antiestrogen clomifen completely blocked the binding. In the presence of clomifen estradiol had no effect on phosphodiesterase activity. It is suggested that estrogen receptors are necessary for the effect of 17 beta-estradiol on phosphodiesterase to be realized in uterine tissue.
