Moreover, the combination of MK-1775 and a dual PI3K and HDAC inhibitor, CUDC-907, can synergistically inhibit cell proliferation and dramatically induces apoptosis in prostate cancer cells. This effect is partially mediated by DNA damage, resulting from the downregulation of DNA damage response (DDR) proteins such as CDK, CHK, and RRM1/2.
