Thus, other published works reported DIABLO overexpression in BC, lung, bladder, cervical, pancreas, prostate, melanoma, glioma [48,49], ER-positive BC cell lines, such as MCF7 that is an ER-positive and PR-positive luminal A BC subtype [138], as well as in ER-positive BC in comparison with ER-negative tissue samples, demonstrating a poor prognosis in BC patients [137]. This evidence concerns the gene ESR1 and breast cancer.
