A key mRNA-miRNA-lncRNA regulatory network related to HNSCC prognosis was ultimately established, including four mRNAs (EIF3D, EIF1, LARP1, and METTL1), one miRNA (hsa-miR-30b-5p), and two lncRNAs (LINC00707 and SNHG16) (Figure 13E). The gene discussed is EIF1; the disease is head and neck squamous cell carcinoma.
