Polo-like Kinase 1 Facilitates Loss of Pten Tumor Suppressor-induced Prostate Cancer Formation

Abstract excerpt

Loss of the tumor suppressor Pten (phosphatase and tensin homolog deleted on chromosome 10) is thought to mediate the majority of prostate cancers, but the molecular mechanism remains elusive. In this study, we demonstrate that Pten-depleted cells suffer from mitotic stress and that nuclear function of Pten, but not its phosphatase activity, is required to reverse this stress phenotype. Further, depletion of Pten...
