Abstract: The invention involves methods of inhibiting the cancer cell cycle to make cancer cells more susceptible to chemotherapeutic agents. In particular, inhibition of CDK4 and/or CDK6 inhibits cell cycle progression in cancer cells. When combined with chemotherapy such cell cycle inhibition can effectively treat even aggressive cancer types that are drug-resistant and intractable to most chemotherapies.

Abstract: Provided herein are methods for the treatment of multiple myeloma, wherein the methods comprise administration of lenalidomide and administration of a second active agent such as a CDK inhibitor.

Abstract: The present invention relates to a method of determining the presence of a retinoblastoma protein (Rb)-mediated cancerous or pre-cancerous condition in a sample of fixed cells that involves exposing the sample to an antibody that recognizes phosphorylation of serine on the retinoblastoma protein (pS-Rb), and identifying cells in the sample that are recognized by the antibody to pS-Rb, where the recognition of pS-Rb in the sample determines the presence of an Rb-mediated cancerous or pre-cancerous condition. The method also involves identifying the presence of specific cell cycle markers and positive and negative cell cycle regulators to assess the stage of disease progression in a cancer patient having an (Rb)-mediated cancer. The present invention also relates to methods of assessing the efficacy of cancer therapy for an Rb-mediated cancer, determining the mechanism of cell cycle progression in an Rb-mediated cancer, and identifying cells predisposed to developing an Rb-mediated cancerous condition.
