title: Adenosine 3',5'-cyclic monophosphate and guanosine 3',5'-cyclic monophosphate levels in human breast cancer tissue.
abstract: Intracellular levels of adenosine 3',5'-cyclic monophosphate and guanosine 3',5'-cyclic monophosphate were measured in breast carcinomas. These levels were increased significantly as compared to normal breast tissues. In benign breast tumors, intermediate levels of adenosine 3'5'-cyclic monophosphate were observed, but they did not differ significantly with malignant tissues. No relation has been shown with estradiol or progesterone binding sites.
