Co-targeting p53-R249S and CDK4 synergistically suppresses survival of hepatocellular carcinoma cells.

Abstract excerpt

p53-R249S (p53-RS) is frequently detected in human hepatocellular carcinoma (HCC) that is highly associated with hepatitis B infection and aflatoxin B1 exposure. Our previous study showed that CDK4/Cyclin D1 phosphorylates p53-RS at the cancer-derived Ser249 and promotes its interaction with c-Myc in the nucleus, consequently enhancing c-Myc-dependent ribosomal biogenesis and HCC cell proliferation. Here we...
