The present study also confirmed that palbociclib could inhibit cell proliferation and induce cell cycle arrest at the G 1 phase in GC cells in a dose-dependent manner. WebOct 10, 2024 · Since CDK4/6 inhibition is thought to induce cell cycle arrest at the G1/S checkpoint, much interest has been focused on combining CDK4/6 inhibitors with cytotoxic agents active against the S or M phase of the cell cycle to enhance therapeutic efficacy.

WebPalbociclib arrests cells in the G1-phase of the cell cycle by suppressing the phosphorylation of the retinoblastoma protein (Rb) [ 7 ]. The resulting hypo-phosphorylated Rb inhibits the transcriptional activity of E2F, thereby blocking the transcription of critical genes required for entry into S-phase. WebRecent investigations by Vanhevel et al. propose combining the CDK4/6 inhibitor Palbociclib with an analog of vitamin D3 for the treatment of luminal carcinomas. This combination inhibits cell proliferation through arrest at the G1/S stage more efficiently than the single treatments in an ER-positive breast cancer experimental model.
