ENAH and head and neck squamous cell carcinoma: Eight integrin subunits (ITGA1, ITGA3, ITGA5, ITGA6, ITGAV, ITGB1, ITGB5, and ITGB6) were selected for analysis as ENAH downstream candidates based on the observation that their expression levels were increased in OSCC tissues (T/N > 1.5 and p < 0.05) and exhibited positive correlations with ENAH expression in HNSCC tissues (r > 0.3 and p < 0.05; Supplementary Table S8).
