Head and neck squamous cell carcinoma (HNSCC) represents a large majority of cancers arising from the head and neck, especially the oral cavity. Despite advances in therapy, the five-year survival rate remains low due to the number of patients presenting advanced stages of the disease. The role of epithelial-mesenchymal transition (EMT) in tumorigenesis in HNSCC remains unexplored. The current ...
