Cyclic adenosine 3',5'-monophosphate-binding protein: role in ovariectomy-induced regression of a hormone-dependent mammary tumor in Sprague-Dawley female rats.
Cyclic AMP- and estrogen-binding activities were present in 7,12-dimethylbenz[a]anthracene-induced mammary carcinomas in Sprague-Dawley female rats. Soon after ovariectomy of the host, cyclic AMP binding markedly increased and estrogen binding decreased in regressing tumors. These changes were reversed when tumor growth was resumed following the injection of estradiol-17beta. The data suggested the possible involvement of cyclic AMP binding in the growth control of a hormone-dependent mammary tumor.
