We further analyzed the differential expression of PSMC1, NAGK, AREG, DDOST, ATP6V1E1, KDELR1, PLOD2, TMED10, ALG5, ARF3, and OST4 in HNSCC and normal head and neck tissues and found that compared with normal tissues, there are 11 glycosyl groups in HNSCC tissues. Here, ATP6V1E1 is linked to head and neck squamous cell carcinoma.
