The search for CDK4/6 inhibitor biomarkers has been hampered by inappropriate proliferation assays
R. Foy, K. X. Lew, A. T. Saurin
This paper shows that ATP-based proliferation assays overestimate CDK4/6 inhibitor response due to G1 cell overgrowth, and identifies Cyclin D1 and RB1 as potential biomarkers using DNA-based assays.
