CDK14 and breast cancer: The expression of CDK14 is upregulated in lung cancer, whereas the inhibition of CDK14 expression leads to the suppression of non-small-cell lung cancer proliferation and invasion through the Wnt/β-catenin signalling pathway.44 A recent study has revealed that miR-455 inhibits breast cancer cell proliferation by targeting CDK14,41 as was also demonstrated in OS cells in our study.
