The roles of cAMP and cAMP-dependent protein kinase in forskolin's actions on Y1 adrenocortical tumor cells.

abstract：:The determination of DNA ploidy and the study of the cell cycle in adrenocortical tumoral cells could help in the distinction between benign and malignant lesions and also in the prediction of the biological behaviour of these tumors. We analysed 32 cases of adrenal tissue (8 normal adrenals--N, 12 benign adenomas--A ...
