Rb1 inactivation
WebMar 18, 2024 · Mechanistic investigations showed that acquired resistance to CDK4/6 inhibition resulted from bypass of cyclin D1–CDK4/6 dependency through selection of CCNE1 amplification or RB1 loss. Notably, although PI3K inhibitors could prevent resistance to CDK4/6 inhibitors, they failed to resensitize cells once resistance had been acquired.
