PLK1 TARGET PHOSPHORYLATION STATUS AND TREATMENT OF CANCER WITH PLK1 INHIBITORS

Abstract:

Provided is a method comprising determining polo-like kinase 1 (PLK1) activity in a cancer in a patient by measuring phosphorylation of a PLK1 target (a) prior to treatment of (i) the patient or (ii) a cancer sample from the patient with a PLK1 inhibitor, and (b) after the treatment. Also provided is a method comprising determining polo-like kinase 1 (PLK1) activity in a cancer in a patient by measuring phosphorylation of a PLK1 target without treatment with a PLK1 inhibitor.
