Following induction with TNF-α, mono- and co-cultures of BMSCs and the established HNSCC cell line PCI-13 were analyzed; protein expression of E-cadherin and vimentin and qRT-PCR expression of Snail, Twist, MMP14, vimentin, E-cadherin, and β-catenin were examined, and changes in cellular AKT signalling were analyzed.
Tumor necrosis factor-α triggers opposing signals in head and neck squamous cell carcinoma and induces apoptosis via mitochondrial- and non-mitochondrial-dependent pathways.
Stabilization of Slug by NF-κB is Essential for TNF-α -Induced Migration and Epithelial-Mesenchymal Transition in Head and Neck Squamous Cell Carcinoma Cells.
The current investigations identified a subset of HPV-positive HNSCCs with mutations in the genes TRAF3 (tumor necrosis factor receptor-associated factor 3) and CYLD (cylindromatosis lysine 63 deubiquitinase).
The expressions of chemokines of IL-8, IL-1β and IL-6 and the cytokines of tumor necrosis factor-α (TNF-α) were higher in HNSCC patient tissues than in non-cancerous matched tissues (NCMT) whereas the expression of IL-10 was lower.
The main aim was to investigate the potential prognostic significance of tumor necrosis factor-like weak inducer of apoptosis (TWEAK), and its receptors, fibroblast growth factor-inducible 14 (Fn14) and CD163, in head and neck squamous cell carcinoma (HNSCC).
Here, we investigated the effects of the proteasome inhibitor MG132 in combination with tumor necrosis factor-related apoptosis inducing ligand (TRAIL) or agonistic TRAIL receptor 1 (DR4)-specific monoclonal antibody, AY4, on sensitization of TRAIL- and AY4-resistant human HNSCC cell lines.
Apigenin induces apoptosis via tumor necrosis factor receptor- and Bcl-2-mediated pathway and enhances susceptibility of head and neck squamous cell carcinoma to 5-fluorouracil and cisplatin.
We investigated the -308 promoter region polymorphisms of the TNF-α gene and its association with the clinicopathological factors of a head and neck squamous cell carcinoma (HNSCC) sample.
The aim of the study was to investigate relationship between activity of superoxide dismutase (SOD), malondialdehyde (MDA) and tumor necrosis factor alpha (TNFalpha) and between Ala-9Val polymorphism in the gene encoding MnSOD (SOD2) and the initial stage and prognosis of the head and neck squamous cell carcinoma (HNSCC).
The purpose of this study was to examine the effect of combined treatment with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and cisplatin in human head and neck squamous cell carcinoma.
The secretion of interleukin (IL)-1 beta, IL-6 and tumour necrosis factor (TNF)-alpha were compared when freshly isolated autologous monocytes or monocytederived macrophages (MDMs) were co-cultured in vitro with autologous fragment (F)-spheroids established from a series of head and neck squamous cell carcinoma (HNSCC) patients.
These TNF-alpha resistant HNSCC lines expressed TNF receptor I, and exhibited constitutive and TNF-alpha-inducible activation of NF-kappaB as demonstrated by nuclear localization of NF-kappaB p65 by immunohistochemistry.
We report here that exposure of primary head and neck squamous cell carcinoma (HNSCC)-derived cells (PCI-04A) to ionizing radiation (IR) or tumor necrosis factor-alpha (TNF-alpha) resulted in an increased level of ACT mRNA, although the induction patterns were different.
In HNSCC, enhanced expression of TNF receptors on the cancer cells occurs and is likely to contribute to the regulation of TNF and its activation of tumor cells within the tumor microenvironment; targeting these receptors in cancer cells may provide a new approach to controlling tumor growth and metastasis.
