Intracrinology
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.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
