2-methoxyestradiol (2-ME2), an endogenous metabolite of 17β -estradiol (E2) with oral activity, is an apoptosis inducer and angiogenesis inhibitor with effective antitumor activity. Methoxyestradiol can also destabilize microtubules. Methoxyestradiol is a potent inhibitor of superoxide dismutase (SOD) and reactive oxygen species (ROS) that can induce autophagy in transformed cell line HEK293, cancer cell line U87 and HeLa.

Cell lines | MCF-7 and MDA-MB-231 cells |
Preparation method | Cell culture and cell treatment. MCF-7 estrogen receptor-positive (ER+ve) human breast cancer cells, MDA-MB-231 ER-negative (ER−ve) human breast cancer cells were obtained from the American Type Culture Collection (LGC Promochem, Teddington, UK). Cells were routinely cultured in RPMI-1640 medium supplemented with 10% (v/v) fetal calf serum, 1% L-glutamine (200 mM), 1% non-essential amino acids (100 ×) and 1% bicarbonate (7.5%) from Sigma and maintained in a humidified incubator under 5% CO2 atmosphere at 37°C. For experiments using hypoxic conditions, cells were incubated under 1% O2 and 5% CO2 atmosphere at 37°C. |
