In line with this finding, KDM4C copy number amplification was uniquely correlated with a lower trend of cisplatin sensitivity in basal cell lineage in the DepMap51 breast cancer cell line data, while response to paclitaxel, 5-fluorouracil and doxorubicin was not correlated (Supplementary Fig. 2e). This evidence concerns the gene KDM4C and breast cancer.
