PDZ-binding kinase inhibitor OTS514 suppresses the proliferation of oral squamous carcinoma cells. Oral Dis 2024; 30:223-234. [PMID: 36799330 DOI: 10.1111/odi.14533] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 12/28/2022] [Accepted: 02/09/2023] [Indexed: 02/18/2023]
Abstract
OBJECTIVE PDZ-binding kinase (PBK) has been reported as a poor prognostic factor and is a promising molecular target for anticancer therapeutics. Here, we aimed to investigate the effect of specific PBK inhibitor OTS514 on the survival of OSCC cells. METHODS Four OSCC cell lines (HSC-2, HSC-3, SAS, and OSC-19) were used to examine the effect of OTS514 on cell survival and apoptosis. DNA microarray analysis was conducted to investigate the effect of OTS514 on gene expression in OSCC cells. Gene set enrichment analysis was performed to identify molecular signatures related to the antiproliferative effect of OTS514. RESULTS OTS514 decreased the cell survival of OSCC cells dose-dependently, and administration of OTS514 readily suppressed the HSC-2-derived tumor growth in immunodeficient mice. Treatment with OTS514 significantly increased the number of apoptotic cells and caspase-3/7 activity. Importantly, OTS514 suppressed the expression of E2F target genes with a marked decrease in protein levels of E2F1, a transcriptional factor. Moreover, TP53 knockdown attenuated OTS514-induced apoptosis. CONCLUSION OTS514 suppressed the proliferation of OSCC cells by downregulating the expression of E2F target genes and induced apoptosis by mediating the p53 signaling pathway. These results highlight the clinical application of PBK inhibitors in the development of molecular-targeted therapeutics against OSCC.

Inhibition of VEGFR2 and EGFR signaling cooperatively suppresses the proliferation of oral squamous cell carcinoma. Cancer Med 2023; 12:16416-16430. [PMID: 37341071 PMCID: PMC10469792 DOI: 10.1002/cam4.6282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 06/05/2023] [Accepted: 06/12/2023] [Indexed: 06/22/2023] Open
Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) is frequently overexpressed in oral squamous cell carcinoma (OSCC), and EGFR-targeting therapeutics have been widely employed to treat patients with a variety of carcinomas including OSCC. Here, we aimed to investigate alternative signaling for OSCC survival under the disruption of EGFR signaling. METHODS OSCC cell lines, namely HSC-3 and SAS, were utilized to investigate how EGFR disruption affects cell proliferation. Gene set enrichment analysis was performed to examine how EGFR disruption affects oncogenic signaling in OSCC cells. Disruption of KDR gene was performed using CRISPR/Cas9 techniques. A VEGFR inhibitor, vatalanib was used to research the impact of VEGFR inhibition on OSCC survival. RESULTS EGFR disruption significantly decreased the proliferation and oncogenic signaling including Myc and PI3K-Akt, in OSCC cells. Chemical library screening assays revealed that VEGFR inhibitors continued to inhibit the proliferation of EGFR-deficient OSCC cells. In addition, CRISPR-mediated disruption of KDR/VEGFR2 retarded OSCC cell proliferation. Furthermore, combined erlotinib-vatalanib treatment exhibited a more potent anti-proliferative effect on OSCC cells, compared to either monotherapy. The combined therapy effectively suppressed the phosphorylation levels of Akt but not p44/42. CONCLUSION VEGFR-mediated signaling would be an alternative signaling pathway for the survival of OSCC cells under the disruption of EGFR signaling. These results highlight the clinical application of VEGFR inhibitors in the development of multi-molecular-targeted therapeutics against OSCC.

ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2021; 8:e2102561.

Abstract
Photodynamic therapy (PDT) has become a promising candidate for cancer theranostics; however, traditional photosensitizers (PSs) usually exhibit weak fluorescence and poor reactive oxygen species (ROS) generation efficiency when aggregated. Recently, aggregation-induced emission (AIE) luminogens have shown great potential in the development of novel PSs owing to their excellent aggregation-induced ROS generation (AIG-ROS) activity. However, there are still concerns that must be addressed. In this study, two near-infrared (NIR) emitters (PI and PTI) are synthesized with AIG-ROS characteristic. PTI exhibit a valuable redder emission with more effective intersystem crossing (ISC) process than PI. The two AIE-active PSs show excellent lipid droplet (LD)-specific targeting ability. The detailed therapeutic mechanism of PDT in LDs specificity is also investigated. The mechanism of oxidation of polyunsaturated fatty acids (PUFAs) in LDs to form toxic lipid peroxides (LPOs) and thereby causing cellular ferroptosis is confirmed first. Homologous targeting is also used to achieve tumor targeting via coating PSs with active cancer cell membranes. Biomimetic aggregates exhibit good targeting ability, and an improved PDT antitumor effect via AIG-ROS activity. These findings offer a clear route to develop advanced PSs with good targeting specificity. A template has also been provided for studying the therapeutic mechanism of AIE-active PSs.

Abstract
BACKGROUND/PURPOSE Radiotherapy for head and neck cancer often causes severe oral mucositis. The purpose of this retrospective study was to further examine the risk factors for developing severe oral mucositis in patients with oral cancer undergoing radiotherapy as a compliment to a previous study performed by our group. MATERIALS AND METHODS A total of 181 patients with oral cancer undergoing radiotherapy were enrolled in the study. The association between a number of potential risk factors and grade 3 oral mucositis were analyzed using the cox proportional hazard model and a logistic regression analysis. RESULTS Grade 3 oral mucositis occurred in 56 patients. The cox proportional hazard model analysis revealed that those with lower hemoglobin levels, concurrent cisplatin and cetuximab administration, and a larger number of teeth showed a significantly higher incidence of severe oral mucositis. Logistic regression analysis revealed that patients who had lower hemoglobin levels, received concurrent cisplatin or cetuximab treatment, and were not administered pilocarpine showed a significantly higher incidence of severe oral mucositis. The presence of teeth may stimulate the oral mucosa and become a risk factor for mucositis, and the administration of pilocarpine might reduce the risk. CONCLUSION This study describes the risk factors of severe radiation-induced oral mucositis in oral cancer patients and shows the possibility of risk reduction by pilocarpine. This information could help patients avoid painful mucositis.

The baseline oral microbiota predicts the response of locally advanced oral squamous cell carcinoma patients to induction chemotherapy: A prospective longitudinal study. Radiother Oncol 2021; 164:83-91. [PMID: 34571091 DOI: 10.1016/j.radonc.2021.09.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Revised: 09/17/2021] [Accepted: 09/20/2021] [Indexed: 01/07/2023]
Abstract
PURPOSE Among oral squamous cell carcinoma (OSCC) patients who receive docetaxel, cisplatin, and 5-fluorouracil (TPF) induction chemotherapy, those with a favorable pathological response tend to obtain satisfactory clinical outcomes, while the total population exhibit no survival benefit. Thus, there is an urgent need to improve the therapeutic effect of TPF by applying personalized treatment according to distinct biomarkers. METHODS AND MATERIALS In the present study, we collected oral rinse samples from 44 OSCC patients enrolled in our prospective multicenter random phase II trial before TPF induction chemotherapy to conduct 16S rRNA gene sequencing and metagenomic analysis. Patients were administrated with two cycles of TPF induction chemotherapy (75 mg/m2 cisplatin and 75 mg/m2 docetaxel on day 1 and 750 mg/m2 fluorouracil from the first to the fifth day), and then divided into responsive and nonresponsive groups according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. RESULTS In the 16S rRNA gene sequence analysis, Fusobacterium and Mycoplasma were more enriched in the nonresponsive group, while Slackia was more enriched in the responder group at the genus level. In the metagenomic shotgun sequencing analysis, Fusobacterium nucleatum was more enriched in the nonresponsive group. Functional analysis showed that the platinum drug resistance pathway and microRNAs in cancer and RNA degradation pathways were remarkably associated with patient sensitivity to induction chemotherapy. CONCLUSIONS Our data suggest that the oral microbiome may play an important role in the OSCC patient sensitivity to TPF induction chemotherapy and offer novel potential biomarkers for predicting the response to TPF induction chemotherapy.

Abstract
OBJECTIVE To assess the value of the texture analysis of fluorine-18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) in predicting the treatment response of postoperative recurrent or metastatic oral squamous cell carcinoma (POR/M-OSCC) treated with cetuximab. METHODS A total of 14 patients undergoing 18F-FDG-PET/CT with POR/M-OSCC were divided into the responder and non-responder groups according to cetuximab response by Response Evaluation Criteria in Solid Tumors (RECIST). The regions of interest (ROI) were set at the POR/M-OSCC lesions with the highest uptake of 18F-FDG, and the volumetric and texture features were analyzed. The features with correlation coefficient of 0.6 or more were further evaluated using the logistic regression analysis to create a model. RESULTS The SHAPEVolume(vx), SHAPEVolume(mL), metabolic tumor volume (MTV), and gray-level run-length matrix run-length nonuniformity (GLRLMRLNU) were significantly different between the responder (n = 6) and non-responder (n = 8) groups (p = 0.044, 0.042, 0.047, and 0.012, respectively). The model's area under the curve (AUC) was found to be 0.83, 0.83, 0.79, and 0.92, respectively. The heatmap with PET feature dendrogram showed four distinct clusters including them in patient's responder and non-responder groups. CONCLUSIONS Higher MTV, GLRLMRLNU, SHAPEVolume(vx), and SHAPEVolume(mL) in 18F-FDG-PET images may have the prediction values for treatment response with POR/M-OSCC treated with cetuximab.

Prolonged cetuximab treatment promotes p27 Kip1-mediated G1 arrest and autophagy in head and neck squamous cell carcinoma. Sci Rep 2021; 11:5259. [PMID: 33664437 PMCID: PMC7933308 DOI: 10.1038/s41598-021-84877-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Accepted: 02/22/2021] [Indexed: 12/16/2022] Open
Abstract
Cetuximab, an anti-epidermal growth factor receptor (EGFR) monoclonal antibody, is an efficient anti-tumor therapeutic agent that inhibits the activation of EGFR; however, data related to the cellular effects of prolonged cetuximab treatment are limited. In this study, the long-term cellular outcome of prolonged cetuximab treatment and the related molecular mechanism were explored in a head and neck squamous cell carcinoma cell line constitutively expressing a fluorescent ubiquitination-based cell cycle indicator. Fluorescent time-lapse imaging was used to assess clonal growth, cell motility, and cell-cycle progression. Western blot analysis was performed to measure the level of phosphorylation and protein-expression following cetuximab treatment. Over 5 days cetuximab treatment decreased cell motility and enhanced G1 phase cell arrest in the central region of the colonies. Significantly decreased phosphorylation of retinoblastoma, Skp2, and Akt-mTOR proteins, accumulation of p27Kip1, and induction of type II LC3B were observed over 8 days cetuximab treatment. Results of the present study elucidate the cetuximab-dependent inhibition of cell migration, resulting in high cell density-related stress and persistent cell-cycle arrest at G1 phase culminating in autophagy. These findings provide novel molecular insights related to the anti-tumor effects of prolonged cetuximab treatment with the potential to improve future therapeutic strategy.

Abstract
BACKGROUND/PURPOSE Palbociclib is an FDA-approved cyclin-dependent kinase (CDK) 4/6 inhibitor that has been clinically proven to be effective in breast cancer. However, its use in oral cancer is not well researched. In this study, we investigated the inhibitory activity of palbociclib against oral squamous cell carcinoma (OSCC) cells and explored the mechanism of inhibition. METHODS The effects of palbociclib on the cytotoxicity of OSCC cells were determined by MTT and colony formation assays. β-Galactosidase staining and cell-cycle analysis were used to determine palbociclib-induced cellular senescence and apoptosis of OSCC cells. Wound healing and transwell assays were performed to assess the effects of palbociclib treatment on migration and invasion ability of OSCC cells. Whole transcriptome sequencing was conducted to show the relationship between DNA damage repair of OSCC cells and palbociclib treatment. Palbociclib-induced DNA damage and repair capacity of OSCC cells were confirmed by comet assay and immunofluorescence confocal microscopy. Western blotting was used to verify the palbociclib-mediated changes in the CDK/pRB/c-Myc/CDC25A pathway. Finally, in vitro findings were tested in a mouse xenograft model. RESULTS Our results showed that palbociclib can significantly inhibit the growth, migration, and invasive ability of OSCC cells and can accelerate cellular senescence and apoptosis. We found that palbociclib induced DNA damage and p21 expression through the p53-independent pathway, thereby downregulating c-Myc and CDC25A expression to inhibit cell cycle progression. In addition, palbociclib downregulated RAD51 expression to inhibit DNA damage repair ability of OSCC cell. CONCLUSION Palbociclib was found to have anti-oral squamous cell carcinoma activity and to simultaneously induce DNA damage and inhibit its repair, and to accelerated cellular senescence and apoptosis.

Oncol Rep 2020; 44:863-872. [PMID: 32705230 PMCID: PMC7388413 DOI: 10.3892/or.2020.7674] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Accepted: 03/31/2020] [Indexed: 12/12/2022] Open
Abstract
High expression of the 110 kDa catalytic subunit of the class IA PI3K (PI3Kp110α) may play an important role in cetuximab resistance exhibited by both colorectal cancer and head and neck squamous cell carcinoma. Therefore, the present study aimed to examine the association between the expression of proteins in the PI3Kp110α pathway and cetuximab resistance, and the antitumor effects of alpelisib (PI3K inhibitor) and cetuximab in oral squamous cell carcinoma (OSCC) cells. The association between PI3Kp110α protein expression levels and the tumor response to cetuximab was determined using immunohistochemistry. OSCC cells were treated with alpelisib, cetuximab, or in combination, and the effects were examined in vitro and in vivo. PI3Kp110α protein expression was significantly associated with the tumor response to cetuximab (P<0.05) and 1-year progression-free survival and overall survival (P<0.05). Combined treatment of alpelisib and cetuximab resulted in enhanced antitumor effects in vitro compared with either agent administered alone. In particular, the expression level of N-cadherin, an epithelial-mesenchymal transition-related protein, was decreased, suggesting that the invasion potential of cetuximab-resistant cells decreased. Furthermore, the expression of proteins in the PI3K pathway were decreased in tumors from mice with OSCC xenografts treated with alpelisib and cetuximab in combination. These results indicate that novel regimens of systemic therapy (such as chemotherapy), with combinations of cetuximab and alpelisib, may be beneficial for patients with cetuximab-resistant OSCC.

Abstract
Oral cavity squamous cell carcinomas (OSCCs) are aggressive tumors, and their recurrence leads to poor prognosis and reduced survival rates. This study aimed to identify therapeutic targets and to evaluate the efficacy of targeted inhibitors in OSCC patient-derived xenograft (PDX) models. Herein, we reported that OSCC PDXs recapitulated the genomic signatures of their paired primary tumors and the expression of CHEK1, PIK3CA, and PIK3CD was significantly upregulated in OSCC. The antitumor efficacy of CHK1 inhibitors (PF477736, AZD7762, LY2606368) and PI3K inhibitors (BYL719, GDC0941, GSK1059615) was investigated in OSCC cell lines and PDX models. Targeting either CHK1 or PI3K effectively inhibited cell proliferation and colony formation by inducing cell cycle arrest and apoptosis in in vitro cell-based assays. Cisplatin-based chemotherapy combined with CHK1 inhibitor treatment synergistically inhibited cell proliferation by suppressing CHK1 phosphorylation and inducing PARP cleavage. Furthermore, compared with monotherapy, cotreatment with CHK1 and PI3K inhibitors exerted synergistic anticancer effects by suppressing CHK1, AKT, and 4E-BP1 phosphorylation. In summary, our study identified CHK1 and PI3K as promising targets, especially in a dual treatment strategy combining a CHK1 inhibitor with cisplatin or a PI3K inhibitor as a novel therapeutic approach for OSCC patients with aberrant cell cycle regulation and PI3K signaling activation.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the most common malignancies worldwide. Although great progress has been made in diagnosis and treatment strategies in recent years, the 5-year survival rate of OSCC patients is still disappointingly low. Hence, there is still an unmet medical need for sufferers with OSCC. As a downstream effector of Hippo pathway, TAZ was up-regulated in multiple cancers including OSCC, and considered as an effective therapeutic target. In this study, we constructed a stable transfected cell line HEK293-TAZ to screen TAZ inhibitor using dual-luciferase reporter assay, and found a potential TAZ inhibitor AR-42. The results showed that AR-42 effectively suppressed the viability and proliferation of OSCC cells, and induced cellular apoptosis and cell cycle arrest in G2/M phase. Moreover, AR-42 potently inhibited cell invasion and the capacity of sphere-forming, as well as the expression of EMT and cancer stem cell related proteins in OSCC cells, exhibiting potential efficacy against OSCC metastasis and self-renewal of oral cancer stem cell. Further mechanism studies showed that AR-42 inhibited the total amount of TAZ and its paralog YAP mainly through blockade of TAZ/YAP transcription and promotion of TAZ/YAP protein degradation. Additionally, the inhibitory effect of AR-42 against TAZ, as well as its anti-OSCC activity could be also observed in SCC9 xenograft model. Taken together, AR-42 deserves to be further studied as a TAZ inhibitor, and is worthy to be further assessed as a potential drug candidate for OSCC treatment.

Dawei H, Honggang D, Qian W. AURKA contributes to the progression of oral squamous cell carcinoma (OSCC) through modulating epithelial-to-mesenchymal transition (EMT) and apoptosis via the regulation of ROS. Biochem Biophys Res Commun 2018; 507:83-90. [PMID: 30454901 DOI: 10.1016/j.bbrc.2018.10.170] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Accepted: 10/27/2018] [Indexed: 11/26/2022]
Abstract
Oral squamous cell carcinoma (OSCC) is known as one of the most common cancer influencing the head and neck region. However, the molecular mechanisms revealing OSCC progression is largely unclear. Aurora kinase A (AURKA) is a serine-threonine kinase that functions in mitotic spindle formation and chromosome segregation, and is associated with the progression of human cancers. But its role in regulating OSCC development has not yet been investigated. In the study, we found that AURKA expression was up-regulated in OSCC cell lines and tumor specimens from patients. OSCC patients with high expression of AURKA exhibited a significant decreased overall survival rate. In vitro, AURKA knockdown markedly reduced the proliferation, migration and invasion of OSCC cells using cell counting kit-8 (CCK-8), EdU, colony formation and transwell analysis. EMT was suppressed by AURKA silence, as evidenced by the up-regulated expression of E-cadherin and down-regulated Vimentin in OSCC cells. In addition, apoptosis was markedly induced by AURKA inhibition through promoting the expression of cleaved Caspase-3 and poly (ADP)-ribose polymerase (PARP). Reactive oxygen species (ROS) production was also markedly enhanced in AURKA-knockdown OSCC cells. Importantly, we found that repressing ROS generation using its scavenger of n-acetylcysteine (NAC) significantly abolished AURKA silence-induced apoptosis, accompanied with restored proliferation and EMT. In vivo, AURKA knockdown notably inhibited tumor growth. Therefore, knockdown of AURKA suppressed cell proliferation, migration and invasion, and also induced apoptosis and ROS generation in OSCC possibly via the production of ROS, demonstrating that AURKA inhibition might represent a novel therapeutic target for the prevention of OSCC.
