NOX1 and metastatic malignant neoplasm in the lymph nodes: Separately, higher expression of GPX4 were clinically correlated with higher lymph node metastasis (p = 0.029), lower NOX1 correlated with higher tumor invasion stage (p = 0.001), and lower FACL4 indicated more distant metastasis (p = 0.001), these were all demonstrated in Figure 2D–F.
