We obtained immunohistochemical staining images of the protein expression of 15 PR-DE-FRGs (ASNS, AURKA, FTH1, SLC2A3, SLC7A5, CISD2, PRDX6, ATG5, BAP1, MAP1LC3A, SOCS1, BNIP3, MAP3K5, ZFP69B, and FBXW7) in HNSCC and normal tissues of the head and neck (Figure 13). Here, ATG5 is linked to head and neck squamous cell carcinoma.
