We started by evaluating the expression of SLC7A11 mRNA in T24 and UM-UC-3 BC cell lines upon treatment with different concentrations of cisplatin over time and found a significant increase in SLC7A11 as early as 48 h in T24 cells and 72 h in UM-UC-3 cells, using both 5 and 10 μM cisplatin (Supplementary Figure S5A). The gene discussed is SLC7A11; the disease is breast cancer.
