Despite the fact that metastasis is the leading cause of death in patients with head and neck squamous cell carcinoma, fundamental questions about the mechanisms that enable or inhibit metastasis remain unanswered. Tetraspanin CD63 has been linked to tumor progression and metastasis. However, few studies have examined the role of CD63 in HNSCC. In this study, we discovered that CD63 levels were abnormally altered in HNSCC tissue compared to adjacent tissue (n = 69 pairs), and that this was linked to prognosis. Through functional in vitro and in vivo experiments, the roles of CD63 in HNSCC were confirmed. Overexpression of CD63 inhibited the progression and metastasis of HNSCC cells. Using mass spectrometry and co-immunoprecipitation assays, we discovered that KRT1 could be a direct interacting partner of CD63. Furthermore, both CD63 and KRT1 expression was significantly decreased in metastatic tissue compared with primary tumor tissue (n = 13 pairs), suggesting that CD63 and KRT1 play a role in reducing the metastasis of HNSCC. In summary, we reveal a previously unrecognized role of CD63 in regulating KRT1-mediated cell cycle arrest in HNSCC cells, and our findings contribute to defining an important mechanism of HNSCC progression and metastasis.
