Metastasis is one of the primary causes for high mortality in patients with squamous cell carcinoma of the head and neck (SCCHN). Our previous study showed that chemokine (C-C motif) ligand 18 (CCL18), derived from tumour-associated macrophages (TAMs), regulates SCCHN metastasis by promoting epithelial-mesenchymal transition (EMT) and preserving stemness. However, the underlying mechanism needs to be further investigation. Interestingly, metadherin (MTDH) expression was induced when SCCHN cells were stimulated with recombinant CCL18 protein in this study...

INTRODUCTION: Head and neck squamous carcinoma (HNSCC) is one of the most invasive types of cancer with high mortality. A previous study has indicated that low levels of let-7d and miR-205 in HNSCC patients are correlated with poor survival. Let-7d and miR-205 are tumor suppressors and regulators of epithelial-to-mesenchymal transition (EMT). However, it is unclear if let-7d and miR-205 together influence cancer cells. AIM: To determine if let-7d and miR-205 expression levels influence HNSCC patient outcome...

Hypopharyngeal carcinoma is a common malignant tumor of the head and neck with a very poor prognosis; the median survival time for curatively treated patients was 17.2 months in India. However, cell-based gene therapy holds promise to improve patient outcomes. In this study, we investigated whether human bone marrow mesenchymal stem cells (BMSCs) possess potential homing capacity for hypopharyngeal carcinoma. To monitor the efficiency of BMSC transplantation therapy via reporter gene imaging, we employed a hybrid baculovirus vector containing the Luc-P2A-eGFP fusion or sodium iodide symporter (NIS) sequence under the control of the cytomegalovirus promoter...

Maternal embryonic leucine zipper kinase (MELK) has been reported to serve critical roles in the maintenance of stemness of cancer cells, although its mechanism remains unclear. Since SRY‑box 2 (SOX2) was demonstrated to be involved in self‑renewal and tumorigenicity of head and neck squamous cell carcinoma (HNSCC) and is aberrantly expressed in HNSCC tumors, the association between MELK and SOX2 was examined. Firstly, MELK inhibition was performed by small interfering RNA or MELK inhibitor OTS167, and it was determined that MELK inhibition by these approaches could decrease the SOX2 expression in HNSCC cells and OTS167 could suppress the SOX2 expression in a dose‑dependent manner...

Background: Head and Neck Squamous Cell Carcinoma (HNSCC) tumors are often resistant to therapies. Therefore searching for predictive markers and new targets for treatment in clinically relevant in vitro tumor models is essential. Five HNSCC-derived cell lines were used to assess the effect of 3D culturing compared to 2D monolayers in terms of cell proliferation, response to anti-cancer therapy as well as expression of EMT and CSC genes. Methods: The viability and proliferation capacity of HNSCC cells as well as induction of apoptosis in tumor spheroids cells after treatment was assessed by MTT assay, crystal violet- and TUNEL assay respectively...

Radiotherapy (RT) in patients with cancer can kill cancer cells but also damage normal cells or tissues. During the treatment of patients with head and neck cancer or thyroid cancer, hyposalivation is a representative chronic side effect of radio-damaged salivary glands (SGs). The major symptom of hyposalivation is mouth dryness, resulting in several subsequent long-term complications. No effective therapeutic approaches have been developed to manage this symptom. In this study, we developed the first rat SG tissue-derived decellularized extracellular matrix (dECM) hydrogel (DSGM-hydrogel) as a functional orthotropic bio-scaffold for future efficient SG stem cell therapy...

Cancer stem cells (CSCs) have been shown as a distinct population of cancer cells strongly implicated with resistance to conventional chemotherapy. Metformin, the most widely prescribed drug for diabetes, was reported to target cancer stem cells in various cancers. In this study, we sought to determine the effects of metformin on head and neck squamous cell carcinoma (HNSCC). CSCs and non-stem HNSCC cells were treated with metformin and cisplatin alone, and in combination, and cell proliferation levels were measured through MTS assays...

OBJECTIVES: Currently there are no standard biomarkers of head and neck squamous cell carcinoma (HNSCC) response to therapy. This is, due to a lack of adequate predictive tumor models. To this end, we established cancer organoid lines from individual patient's tumors, and characterized their growth characteristics and response to different drug treatments with the objective of using these models for prediction of treatment response. MATERIALS AND METHODS: Forty-three patients' samples were processed to establish organoids...

Human papillomavirus (HPV) is a major causative agent of head and neck squamous cell carcinomas (HNSCC). Over the past several decades, an increasing number of studies established the strong association of HPV with the invasion and metastasis of HNSCC. In the present study, we reviewed the gene mutations in HPV-associated HNSCC and the unique mechanism of E6- and E7-mediated carcinogenesis via interactions with an array of cellular elements. We further discussed the progress in the mechanisms of invasion and metastasis; these mechanisms include non-coding RNAs, deregulating cellular energetics, tumor microenvironment, cancer stem cells, angiogenesis, and lymphangiogenesis...

The Hippo-YAP (Yes-associated protein) pathway is a key regulator of tissue growth, organ size and stem cell function. More recently, a fundamental role for this pathway has emerged in stem cell function and tumorigenesis. Activation of the transcriptional co-activator YAP promotes cell-contact independent proliferation, epithelial to mesenchymal transition (EMT), cancer stem cell features and drug resistance. In this review, we describe the main components of the pathway, the microenvironment and the cell-intrinsic cues governing its activation, the downstream players of the pathway and the biological implications of their activation in the context of cancer...

Protein tyrosine kinase 7 (PTK7) and cancer-associated fibroblasts (CAFs) play important roles in cancer stemness, respectively. However, little is known about interaction between CAFs and PTK7 in cancers. In this study, we showed that PTK7 was significantly correlated with the Wnt/β-Catenin pathway and aggressive clinicopathologic features in human head and neck squamous cell carcinoma (HNSCC). Meanwhile, animal experiments showed that PTK7 enhanced chemoresistance and lung metastasis of HNSCC in vivo. In addition, co-immunoprecipitation (co-IP) assay demonstrated that POSTN secreted by CAFs was a potential upstream ligand of PTK7 which might act as a receptor...

Head and neck squamous cell carcinoma (HNSCC) is one of the leading causes of cancer deaths worldwide, especially in male. With poor prognosis, significant portions of patients with HNSCC die due to cancer recurrence and tumor metastasis after chemotherapy and targeted therapies. The HNSCC FaDu cell ectopic expression of Twist, a key transcriptional factor of epithelial-mesenchymal transition (EMT), which triggers EMT and results in the acquisition of a mesenchymal phenotype, was used as the cell model. Our results demonstrated that treatment with newly synthesized 2-(3-hydroxyphenyl)-5-methylnaphthyridin-4-one (CSC-3436), a flavonoid derivative, elicited changes in its cell morphology, upregulated E-cadherin messenger RNA and protein expression, downregulated N-cadherin, vimentin, and CD133 (a marker associated with tumor-initiating cells) in FaDu-pCDH-Twist cells...

Head and neck cancers are deadly diseases that are diagnosed annually in approximately half a million individuals worldwide. Growing evidence supporting a role for cancer stem cells (CSCs) in the pathobiology of head and neck cancers has led to increasing interest in identifying therapeutics to target these cells. Apart from the canonical tumor-suppressor functions of p53, emerging research supports a significant role for this protein in physiological stem cell and CSC maintenance and reprogramming. Therefore, p53 has become a promising target to sensitize head and neck CSCs to chemotherapy...

Long non-coding RNAs (lncRNAs) are potentially critical regulators of cancer malignant behaviours. Aberrant expression and dysfunction of lncRNA PVT1 have been reported in multiple human cancers. However, its role in squamous cell carcinoma of the head and neck (SCCHN) remains largely unknown. Our current study demonstrated that PVT1 expression was increased in SCCHN. High PVT1 expression was positively correlated with SCCHN clinical parameters including T classification, clinical stages and cervical lymph node metastasis...

Locally advanced head and neck squamous cell carcinomas (HNSCC) have limited prognosis due to frequent treatment failure. Currently, TNM-classification and human papillomavirus (HPV) infection are the sole clinical prognosticators of outcome. Tumor heterogeneity and stemness based on epithelial-mesenchymal-transition reportedly associate with therapy resistance. The capacity of epithelial marker EpCAM (EpEX), stemness regulator Sox2 and mesenchymal marker vimentin to predict clinical outcome of HSNCC patients was assessed upon immunohistochemistry staining in two cohorts of HNSCC patients treated with surgery and adjuvant radio (chemo) therapy (n = 94) and primary radio (chemo) therapy (n = 94), respectively...
