WebFeb 4, 2024 · CDK4/6i alone was not sufficient to eradicate tumors despite reduced tumor proliferation and increased T-cell activation and infiltration in the KP GEMM model , consistent with a previous report that palbociclib reduces the growth of Kras-driven murine lung tumors . We therefore evaluated the ability of CDK4/6i to complement PD-1 blockade. There are multiple regulation points within this signaling pathway. First and foremost, under non-dividing conditions multiple proteins can inhibit the Cyclin D/Cdk4 complex by binding Cdk4 and inhibiting its association with Cyclin D. Primarily, this is accomplished by p27 but it can also be done by p16 and p21. However, this pathway is stimulated by the upstream binding of growth factors (GF), either from within the cell itself or from neighboring cells. Stimulation by growth fac…
