B3GALT4 and ovarian carcinoma: We found decreased expression of B3GALT4 was associated with poor disease-free survival in both ovarian and lung cancers (ovarian cancer: HR = 0.78, 95% CI 0.67–0.89, P = 0.00043; lung cancer: HR = 0.73, 95% CI 0.58–0.92, P = 0.0075, Fig. S7), indicating the likelihood that this gene plays a role in cancer progression.
