Of note, these ovarian cancer cell lines represent different molecular subtypes, epithelial–mesenchymal transition (EMT) status, histologies, and TP53 mutation status (supplementary material, Table S4 [23]), indicating that our study sought to investigate the correlation of putative markers and elimusertib sensitivity in ovarian cancer in general, and not limited to a specific subgroup. Here, TP53 is linked to ovarian carcinoma.
