Use of a Modified Radioligand Assay to Measure the Effect of Estradiol on Uterine Adenosine 3',5'–Cyclic Monophosphate

Abstract
The acute effects of estrogen on castrate rat uterine cAMP were studied employing a well—validated assay procedure for the nucleotide. Estradiol (1 μAg/100 g bw) administered iv produced no alteration in cAMP from 0–30 min of exposure. Using a suspended uterine preparation in vitro, estradiol (0.5–10 μM) was again ineffective under conditions where isoproterenol produced a marked increase in cAMP concentration. It is concluded that acute elevation of cAMP is not a regular feature of estrogen action on the uterus. (Endocrinology92: 494, 1973)
