Polo-like kinase 1: target and regulator of anaphase-promoting complex/cyclosome-dependent proteolysis.
Polo-like kinase 1 (Plk1) is a key regulator of progression through mitosis. Although Plk1 seems to be dispensable for entry into mitosis, its role in spindle formation and exit from mitosis is crucial. Recent evidence suggests that a major role of Plk1 in exit from mitosis is the regulation of inhibitors of the anaphase-promoting complex/cyclosome (APC/C), such as the early mitotic inhibitor 1...
متن کاملPolo-like kinase 1 as target for cancer therapy
Polo-like kinase 1 (Plk1) is an interesting molecule both as a biomarker and as a target for highly specific cancer therapy for several reasons. Firstly, it is over-expressed in many cancers and can serve as a biomarker to monitor treatment efficacy of Plk1 inhibitors. Furthermore, the Plk1 enzyme is expressed only in dividing cells and is a major regulator of the cell cycle. It controls entry ...
متن کاملTargeting polo-like kinase 1, a regulator of p53, in the treatment of adrenocortical carcinoma
BACKGROUND Adrenocortical carcinoma (ACC) is an aggressive cancer with a 5 year survival rate of 20-30 %. Various factors have been implicated in the pathogenesis of ACC including dysregulation of the G2/M transition and aberrant activity of p53 and MDM2. Polo-like kinase 1 (PLK-1) negatively modulates p53 functioning, promotes MDM2 activity through its phosphorylation, and is involved in the G...
متن کاملIdentification of Polo-like kinase 1 as a potential therapeutic target in anaplastic thyroid carcinoma.
Anaplastic thyroid carcinoma (ATC) is one of the most aggressive and chemoresistant cancers. The serine/threonine kinase Polo-like kinase 1 (PLK1), a key regulator of multiple steps during mitotic progression, is highly expressed in ATC. Here, we used the BI 2536 PLK1 inhibitor on ATC and nontransformed thyroid follicular cell lines. Our data show that ATC cells are addicted to high levels of P...
متن کاملEvaluation of Polo-like kinase 1 as a potential therapeutic target in Merkel cell carcinoma.
BACKGROUND Merkel cell carcinoma (MCC) is a rare and aggressive malignancy of the skin. Treatment options for MCC include surgery, radiotherapy, and chemotherapy. The purpose of this study was to assess the expression of Polo-like kinase 1 (PLK1) in MCC and the role of the inhibitor, BI2536, as a potential therapeutic option in MCC. METHODS PLK1 expression was assessed in tissue samples from ...
