体外研究
(In Vitro)

2-Hydroxyestrone exhibits antiestrogen action on MCF-7 human breast cancer cells. Addition of 2-Hydroxyestrone to the cell cultures in concentration of 1-1000 nM has no effect on cell growth and proliferation because of rapid O-methylation of the catechol estrogen by catechol O-methyltransferase which is highly active in these cells. In the presence of quinalizarin, a potent catechol O-methyltransferase inhibitor which reduces the O-methylation of the steroid, 10 and 100 nM 2-Hydroxyestrone markedly suppresses the growth and proliferation of the cells[2].

Cell Proliferation Assay[2]

Cell Line: Human breast cancer cell lines MCF-7, MDA-MB-231, and MDA-MB-330
Concentration: 1-1000 nM
Incubation Time: 6 days
Result: 10 and 100 nM markedly suppressed the growth and proliferation of the cells in the presence of quinalizarin. The tumor cell growth-inhibitory action of the catechol estrogen was neutralized by the presence of 1 nM estradiol.
