Description

General description

Estrone is a weak form of estrogen and exists as estrone sulphate. Estrone is a luteolytic estrogen produced by the corpus luteum. In the follicle, estrone is synthesized from androstenedione by the action of cytochrome P450 aromatase.

Application

Estrone has been used:

• as medium supplement for hormone based degranulation studies of natural killer cells
• as an endocrine disrupting compound for screening bacterial biosensor in toxic water.
• as medium component for monitoring fatty acid synthase (FASN) activity in breast adenocarcinoma cell lines

Biochem/physiol Actions

Estrone is an agonist for the estrogen receptor. The estradiol to estrone interconversion is favourable in menopause. Oral hormone replacement therapy (HRT) of estradiol-17β increases circulating levels of estrone.
