Abstract

A large proportion of androgens in men (40%), and the majority of estrogens in women (75% before menopause and close to 100% after menopause), are synthesized in peripheral target tissues from precursor steroids of adrenal origin. The genes encoding the enzymes responsible for the formation and metabolism of androgens and estrogens are expressed in a large series of peripheral tissues, thus providing the basis for a promising new area in hormone action, namely intracrinology. These steroidogenic and steroid metabolizing enzymes should become a major target of novel therapies for steroid-sensitive diseases, particularly breast and prostate cancer.
