Of interest, the expression of p-STAT3, LC3, LAMP2 and p-Erk1/2 in most of the HNSCC cases (cluster 2) were distinct from normal mucosa (cluster 1), reflecting the significant differences in p-STAT3, LC3, LAMP2 and p-Erk1/2 staining in HNSCC (Figure 6C). The gene discussed is MAP1LC3A; the disease is head and neck squamous cell carcinoma.
