Immunopharmacology Comments
Phenotypic abnormalities in CDK6 knockout mice suggest biological roles in addition to mitotic cell cycle regulation. Alternate roles include involvement in hematopoietic function and inhibition of T cell differentiation [11,15]. The T cell differentiation function is not shared by CDK4. In mixed lineage leukemia (MLL)-rearranged acute myeloid leukemia (AML) depletion of CDK6 (either by shRNA knockdown or using the approved small molecule CDK4/6 inhibitor palbociclib) causes growth inhibition and differentiation of MLL-driven leukemic cells [16].
