We added the selective WEE1 inhibitor (MK-1775) at concentrations of 250 or 500 nM to cell lines of multiple human cancers, including UVM (92.1 and OCM1), SKCM (SKMEL28), non-small cell lung cancer (A549), breast cancer (MCF7), mesothelioma (MSTO-211H and H2373), and pancreatic cancer (PANC1 and Mia-PaCa2). Here, WEE1 is linked to breast carcinoma.
