The Polo-like kinase 1 inhibitor onvansertib represents a relevant treatment for head and neck squamous cell carcinoma resistant to cisplatin and radiotherapy. Theranostics 2021; 11:9571-9586. [PMID: 34646387 PMCID: PMC8490521 DOI: 10.7150/thno.61711] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Accepted: 09/04/2021] [Indexed: 01/19/2023] Open
Abstract
Rationale: Head and neck squamous cell carcinoma (HNSCC) represent the 4th most aggressive cancer. 50% of patients relapse to the current treatments combining surgery, radiotherapy and cisplatin and die two years after the diagnosis. Elevated expression of the polo-like kinase 1 (Plk1) correlated to a poor prognosis in epidermoid carcinomas. Methods: The molecular links between Plk1 and resistance to cisplatin/radiotherapy were investigated in patients and cell lines resistant to cisplatin and/or to radiotherapy. The therapeutic relevance of the Plk1 inhibitor onvansertib, alone or combined with cisplatin/radiotherapy, was evaluated on the proliferation/migration on HNSCC cell lines, in experimental HNSCC in mice, in a zebrafish metastasis model and on patient-derived 3D tumor sections. Results: Plk1 expression correlated to a bad prognosis in HNSCC and increased after relapse on cisplatin/radiotherapy. Onvansertib induced mitotic arrest, chromosomic abnormalities and polyploidy leading to apoptosis of sensitive and resistant HNSCC cells at nanomolar concentrations without any effects on normal cells. Onvansertib inhibited the growth of experimental HNSCC in mice and metastatic dissemination in zebrafishes. Moreover, onvansertib combined to cisplatin and/or radiotherapy resulted in a synergic induction of tumor cell death. The efficacy of onvansertib alone and in combination with reference treatments was confirmed on 3D viable sections of HNSCC surgical specimens. Conclusions: Targeting Plk1 by onvansertib represents a new strategy for HNSCC patients at the diagnosis in combination with reference treatments, or alone as a second line treatment for HNCSCC patients experiencing relapses.

Programmed cell death, redox imbalance, and cancer therapeutics. Apoptosis 2021; 26:385-414.

Abstract
Cancer cells are disordered by nature and thus featured by higher internal redox level than healthy cells. Redox imbalance could trigger programmed cell death if exceeded a certain threshold, rendering therapeutic strategies relying on redox control a possible cancer management solution. Yet, various programmed cell death events have been consecutively discovered, complicating our understandings on their associations with redox imbalance and clinical implications especially therapeutic design. Thus, it is imperative to understand differences and similarities among programmed cell death events regarding their associations with redox imbalance for improved control over these events in malignant cells as well as appropriate design on therapeutic approaches relying on redox control. This review addresses these issues and concludes by bringing affront cold atmospheric plasma as an emerging redox controller with translational potential in clinics.

Mutations of the LIM protein AJUBA mediate sensitivity of head and neck squamous cell carcinoma to treatment with cell-cycle inhibitors. Cancer Lett 2017; 392:71-82. [PMID: 28126323 PMCID: PMC5404895 DOI: 10.1016/j.canlet.2017.01.024] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2016] [Revised: 01/13/2017] [Accepted: 01/16/2017] [Indexed: 01/22/2023]
Abstract
The genomic alterations identified in head and neck squamous cell carcinoma (HNSCC) tumors have not resulted in any changes in clinical care, making the development of biomarker-driven targeted therapy for HNSCC a major translational gap in knowledge. To fill this gap, we used 59 molecularly characterized HNSCC cell lines and found that mutations of AJUBA, SMAD4 and RAS predicted sensitivity and resistance to treatment with inhibitors of polo-like kinase 1 (PLK1), checkpoint kinases 1 and 2, and WEE1. Inhibition or knockdown of PLK1 led to cell-cycle arrest at the G2/M transition and apoptosis in sensitive cell lines and decreased tumor growth in an orthotopic AJUBA-mutant HNSCC mouse model. AJUBA protein expression was undetectable in most AJUBA-mutant HNSCC cell lines, and total PLK1 and Bora protein expression were decreased. Exogenous expression of wild-type AJUBA in an AJUBA-mutant cell line partially rescued the phenotype of PLK1 inhibitor-induced apoptosis and decreased PLK1 substrate inhibition, suggesting a threshold effect in which higher drug doses are required to affect PLK1 substrate inhibition. PLK1 inhibition was an effective therapy for HNSCC in vitro and in vivo. However, biomarkers to guide such therapy are lacking. We identified AJUBA, SMAD4 and RAS mutations as potential candidate biomarkers of response of HNSCC to treatment with these mitotic inhibitors.

Evaluation of Polo-like kinase 1 as a potential therapeutic target in Merkel cell carcinoma. Head Neck 2016; 38 Suppl 1:E1918-25. [PMID: 26713885 DOI: 10.1002/hed.24349] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2015] [Revised: 08/26/2015] [Accepted: 10/17/2015] [Indexed: 02/06/2023] Open
Abstract
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 28 patients with MCC and 5 healthy skin samples via immunohistochemistry and furthermore in the 2 MCC cell lines, MCC13 and MCC26, via immunoblotting. The impact of increasing doses of BI2536 alone and in combination with cisplatin or irradiation on cell viability was measured using the CCK-8 assay. Colony forming assays were performed to evaluate long-term effects of combination treatments. Additionally, the induction of apoptotic cell death was measured via flow cytometry. RESULTS PLK1 is moderately to strongly expressed in 75% of the patients with MCC. The PLK1 inhibitor, BI2536, demonstrated marked inhibition of cell proliferation with IC50 in the low nM range (from 10.07-12.39 nM). Furthermore, BI2536 induces apoptosis in MCC cell lines and acts synergistically in combination with irradiation and cisplatin. CONCLUSION Because of the marked upregulation of PLK1 in MCC tumor samples and potent inhibition of cell proliferation using a specific clinically available inhibitor, targeting of PLK1 qualifies as a potential novel therapeutic strategy in MCC. © 2015 Wiley Periodicals, Inc.

Targeting the Mitotic Catastrophe Signaling Pathway in Cancer. Mediators Inflamm 2015; 2015:146282. [PMID: 26491220 PMCID: PMC4600505 DOI: 10.1155/2015/146282] [Citation(s) in RCA: 134] [Impact Index Per Article: 14.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2014] [Accepted: 05/30/2015] [Indexed: 12/14/2022] Open
Abstract
Mitotic catastrophe, as defined in 2012 by the International Nomenclature Committee on Cell Death, is a bona fide intrinsic oncosuppressive mechanism that senses mitotic failure and responds by driving a cell to an irreversible antiproliferative fate of death or senescence. Thus, failed mitotic catastrophe can promote the unrestrained growth of defective cells, thereby representing a major gateway to tumour development. Furthermore, the activation of mitotic catastrophe offers significant therapeutic advantage which has been exploited in the action of conventional and targeted anticancer agents. Yet, despite its importance in tumour prevention and treatment, the molecular mechanism of mitotic catastrophe is not well understood. A better understanding of the signals that determine cell fate following failed or defective mitosis will reveal new opportunities to selectively target and enhance the programme for therapeutic benefit and reveal biomarkers to predict patient response. This review is focused on the molecular mechanism of mitotic catastrophe induction and signalling and highlights current strategies to exploit the process in cancer therapy.
