FCGBP and head and neck squamous cell carcinoma: Then we detect FcGBP protein expression level in 62 paired HNSCC and surgical safety border tissues, and we found that FcGBP protein expression level was lower in HNSCC compared to surgical safety border tissues (p<0.0001) (Figure 1C), and similar results generated in IHC experiment (p<0.0001) (Figure 1B).
