ST3GAL6 and metastatic malignant neoplasm in the lymph nodes: In the TCGA provisional dataset, up-regulation of ST3GAL6 was observed in UBC patients with lymph node metastasis (≥N1; n=128) or with recurrence (Recurred; n=141), comparing to those without lymph node metastasis (N0; n=235, p < 0.05; Figure S4F) or without recurrence (DiseaseFree; n=178, p < 0.01; Figure S4G), respectively.
