General Description

• Estrone is an aromatized C18 steroid considered one of the major mammalian estrogen and a sex hormone. It shows antineoplastic and bone density conservative activities.

• This compound can interact with estrogen receptors in target tissues to produce similar effects to estradiol. Hormone-bound estrogen receptors dimerize, translocate to the nucleus of cells and bind to estrogen response elements (ERE) of genes. Binding to ERE alters the transcription rate of affected genes.

Applications

• Estrone has the ability to increase the hepatic synthesis of sex hormone binding globulin (SHBG), thyroid-binding globulin (TBG), and other serum proteins.

• It can suppress the release of follicle-stimulating hormone and luteinizing hormone.

• This compound can be produced from androstenedione or testosterone via estradiol. In vivo, it can be generated mainly in the ovaries, placenta, and peripheral tissues (especially adipose tissue) through conversion of androstenedione. It may be metabolized to 16-α-hydroxyestrone, which may be reduced to estriol by estradiol dehydrogenase.

• It has been used as medium supplement for hormone-based degranulation studies of natural killer cells.

• It is used as medium component for monitoring fatty acid synthase activity in breast adenocarcinoma cell lines.
