Rapid adaptation to CDK2 inhibition exposes intrinsic cell-cycle plasticity

0 views | Sep 26 2023

CDK2 inhibitors in preclinical models reveal that acute inhibition of CDK2 leads to rapid loss of substrate phosphorylation, which is compensated by CDK4/6 activity to sustain cell cycle progression, suggesting that co-inhibition of CDK2 and CDK4/6 may be necessary for effective suppression of CDK2-driven cancers.
