Elevated mRNA expression of LGALS4, LGALS8, LGALS10 and LGALS13 was significantly related to a favorable OS in total patients with ovarian cancer, with HR=0.78 (0.69-0.89), P=0.0003; HR=0.86 (0.76-0.99), P=0.032; HR=0.82 (0.71-0.95), P=0.0065; HR=0.81 (0.71-0.94), P=0.0046; HR=0.87 (0.76-1), P=0.045. The gene discussed is CLC; the disease is ovarian cancer.
