CDK1 and breast carcinoma: In addition to our own studies in ovarian cancer cells migrating in 3D cell-derived matrices, knockdown of CDK1 abrogates cell migration and invasion in breast cancer cells (Wang et al., 2021), cholangiocarcinoma cells (Duan et al., 2021) and hepatocellular carcinoma (Dang et al., 2021), and inhibition of CDK1 activity reduces vimentin phosphorylation and migration in Schwann cells (Chang et al., 2012).
