The expression level of SLC7A2 is statistically higher in normal tissues (n = 44) compared with HNSCC tissues (n = 520), and the level of SLC7A2 was upregulated in HPV‐positive HNSCC (n = 97) than that in HPV‐negative HNSCC (n = 421) (Figure 1E). Here, SLC7A2 is linked to head and neck squamous cell carcinoma.
