描述 | Estrogen receptors (ERs) play a key role in breast cancer progression. It is reported that 75% of women diagnosed with breast cancer have estrogen and progesterone receptor-positive breast tumors[3]. 4-Hydroxytamoxifen (Afimoxifene, 4-OH-tamoxifen) is the active metabolite of tamoxifen and a selective estrogen receptor modulator that is widely used in the therapeutic and chemopreventive treatment of breast cancer. 1 µM of 4-OH-tamoxifen treatment for 1h inhibited LM05-E and MCF-7 cells proliferation, and this effect was related to the PI3K/AKT pathway[4]. In the MCF-7:5C cells, addition of 4-OH-tamoxifen at an equimolar concentration at early time points almost completely reversed the apoptosis induced by ethoxytriphenylethylene (10-6 M) after 1 and 2 days of treatment[5]. In vivo, three daily doses of 4-OH-tamoxifen (6 mg/day) effectively attenuated methamphetamine-induced nigrostriatal dopamine depletions in both sexes of intact and gonadectomized C57BL/6 J mice[6]. |
