The Role of TGF-β1 and Mutant SMAD4 on Epithelial-Mesenchymal Transition Features in Head and Neck Squamous Cell Carcinoma Cell Lines

| Resumo: | Head and neck squamous cell carcinomas (HNSCCs) represent more than 90% of all malignancies in the upper aero-digestive tract. Their ability to metastasize is tightly associated with the patient’s survival. The process of epithelial–mesenchymal transition (EMT) is thought to be a central mechanism for invasion and metastasis. Here, we investigated the responsiveness of HNSCC cell lines and the HaCaT control cell line to the EMT master regulator TGF-β1 and observed major differences in the level of sensitivity to this cytokine. The more epithelial HNSCC cells and HaCaT control cells responded more extensively to TGF-β1 than the less epithelial HNSCC cells. Mutant SMAD4 was detected in the most mesenchymal HNSCC cell line and appears to contribute to mesenchymal features in HNSCC cells. These observations could help to explain the different histomorphological phenotypes of HNSCC tumors, which could be linked to the risk of metastatic spread. |
