TNBC cell lines MDA-MB-231 and HCC1937 were obtained from the American Type Culture Collection (Manassas, VA, USA). Both of them were cultured in RPMI 1640 medium (GIBCO, Gaithersburg, MD, USA) supplemented with 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin. Cell cultures were maintained at 37 °C with 5% CO2 in a humidified atmosphere.
