Product information "16alpha-hydroxy Estrone"
The naturally-occurring estrogens are estrone (E1, Cay-10006485), estradiol (E2, Cay-10006315), and estriol (E3, Cay-10006484). 16alpha-hydroxy Estrone (16alpha-OHE1) is a hydroxylated metabolite of E1 as well as an interconversion product with E2. E1 is 16alpha-hydroxylated by cytochrome P450 (CYP) isoforms, including CYP1A1, CYP3A5, CYP3A4, and CYP3A7, with CYP3A5 being breast-specific. 16alpha-OHE1 is sulphatized or glucuronidated before excretion. It is increased in rheumatoid arthritis and decreased by physical activity. Unlike the parent estrogens and other hydroxylated metabolites of E1, 16alpha-OHE1 binds covalently and persistently activates estrogen receptors. In addition, this metabolite increases cell proliferation and does not suppress TNF-alpha secretion, whereas other estrogen metabolites are not pro-proliferative and have marked effects on TNF-alpha secretion. The levels of 16alpha-OHE1 are increased in some forms of hormone therapy. Because hormone therapy increases breast cancer risk, 16alpha-OHE1 has been implicated as a risk factor for breast cancer, although supportive data remains elusive.Formal Name: 3,16alpha-dihydroxy-estra-1,3,5(10)-trien-17-one.
