JUNB and head and neck squamous cell carcinoma: Although the difference in JunB expression between the metastatic and non-metastatic HNSCC cell lines was slight, we decided to clarify the roles of JunB in regulating the pathways related to distant metastasis in HNSCC based on the high scores observed for JunB in the upstream and key node analysis for the current dataset (distant metastatic vs. non-metastatic) and the regional metastatic vs. non-metastatic data set (data not shown).
