Palbociclib fibroblast cell cycle arrest
WebMay 18, 2024 · British Journal of Cancer - CDK4/6 inhibition presents as a therapeutic option for paediatric and adult germ cell tumours and induces cell cycle arrest and apoptosis … 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.

WebPalbociclib has been reported to be efficient, not only at halting proliferation, but also at inducing senescence in different tumor types. In this study, we evaluated the effect of this inhibitor on four patient-derived glioma stem cell-enriched cell lines. 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.
