AQP3 mRNA expression was significantly correlated with better OS for all ovarian cancer patients, HR = 0.77 (0.67–0.89), P=0.00043 (Figure 5A), serous ovarian cancer patients, HR = 0.82 (0.7–0.95), P=0.01 (Figure 5B), and endometrioid ovarian cancer patients, HR = 0.15 (0.03–0.93), P=0.019 (Figure 5C). This evidence concerns the gene AQP3 and ovarian endometrioid adenocarcinoma.
