As shown in Figure 2, the mRNA expression of SNCG in OSCC was not related to lymph node metastasis, T stage, and clinical stage (Figures 2(a)–2(c)), while the mRNA expression of Snai1 in OSCC was related to lymph node metastasis, T stage, and clinical stage (Figures 2(d)–2(f)). The gene discussed is SNAI1; the disease is metastatic malignant neoplasm in the lymph nodes.
