High levels of cyclin D3 and CDK6 may predict response to CDK4/6 inhibitors in multiple tumor types. (aacrjournals.org)
Inhibitors of the cyclin-dependent kinases CDK4 and CDK6 induce cell-cycle arrest in RB1-proficient tumors and have had promising results in several tumor types. (aacrjournals.org)
Thus, the CDK4/6 inhibitor palbociclib reduced NADPH and GSH levels in T-ALL cells, thereby increasing ROS levels to induce apoptosis, which could be rescued by the antioxidant N -acetyl-cysteine. (aacrjournals.org)
Moreover, in breast cancer cells, which express CDK4 instead of CDK6, palbociclib induced cell-cycle arrest instead of apoptosis, further indicating that expression of cyclin D3 and CDK6 in T-ALL cells promotes apoptosis in response to palbociclib. (aacrjournals.org)
Additionally, 16 of 18 nonleukemic cancer cell lines exhibiting high expression of cyclin D3 and CDK6 underwent apoptosis in response to palbociclib, and, in melanoma patient-derived xenografts, high cyclin D3 and CDK6 expression was associated with tumor regression after CDK4/6 inhibition. (aacrjournals.org)
Together, these findings elucidate a prosurvival role for cyclin D3-CDK6 in metabolism, in addition to its role in cell-cycle progression, and suggest that high levels of cyclin D3 and CDK6 may predict response to CDK4/6 inhibitors. (aacrjournals.org)

Introduction The commitment to cell proliferation is set up when extracellular signals converge on the cell cycle and induce the expression of D-type cyclins, their association with CDK4 and/or CDK6, as well as the activation from the holoenzyme complex [1C3]. (healthandwellnesssource.org)
Launch The dedication to cell proliferation is set up when extracellular indicators converge on the cell routine and stimulate the appearance of D-type cyclins, their association with CDK4 and/or CDK6, as well as the activation from the holoenzyme complicated [1C3]. (healthandwellnesssource.org)
Unchecked proliferation of Rb-positive tumor cells is often connected with mutations that dysregulate this pathway: like the overexpression of D-type cyclins, the overexpression or mutation of CDK4, or mutations in the Printer ink4 category of CDK inhibitors [3, 5, 6]. (healthandwellnesssource.org)
