MUC1 and ovarian carcinoma: We have chosen ovarian cancer as the model system for this investigation because it is the fifth leading cause of cancer deaths amongst women—with ~14,000 deaths in the United States alone in 2019—and, as we have mentioned above, because the overexpression of MUC1 has been linked to aggressiveness, invasiveness, metastatic potential, and resistance to therapy in the disease [11,13,35].
