Popis: Background: Although it is well established that the extracellular matrix affects tumour progression, not much is known about the various components and their effect on head and neck squamous cell carcinoma (HNSCC) progression. Levels of collagen type XI α1 (colXIα1), a minor fibrillar collagen, have been shown to be increased in tumour compared with normal tissue in several cancers, including colorectal, breast, and non-small cell lung cancer. Currently, the functional significance of colXIα1 is not understood. Methods: We examined the expression levels of colXIα1 mRNA and elucidated the functional role of colXIα1 in HNSCC. Cell proliferation, invasion, and migration were examined with and without colXIα1 knockdown with siRNA in HNSCC cells. Results: Our data demonstrate that colXIα1 expression is increased in tumour samples compared with levels in normal adjacent tissue in 16/23 HNSCC patients. In addition, colα11 is increased in HNSCC cell lines compared with normal immortalised epithelial cells and is increased in tumour-derived fibroblasts compared with normal fibroblasts. Using an siRNA approach, we demonstrate that colXIα1 contributes to proliferation, migration, and invasion of HNSCC. Conclusion: Our cumulative findings suggest that colXIα1 contributes to HNSCC tumorigenesis and may serve as a potential therapeutic target.
