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. WebJan 6, 2024 · Whether, whether RB1 inactivation is a feature of the tumour at diagnosis prior to treatment or whether it is acquired at the point of drug resistance, may give further insight into its potential role in either predicting or facilitating histological transformation. Consistent with previous efforts, Pros et al. 4.
