Figure 1. miR-520g was upregulated in EOC tissues and high miR-520g expression predicted poor EOC patient survival, especially in recurrent or high serum CA-125 level patients.

(A) Relative miR-520g expression in normal, benign, borderline and EOC tissues (**p < 0.001). (B) Estimation of overall survival curves by Kaplan–Meier analysis with log-rank test in 116 EOC patients according to miR-520g expression. Patients with high miR-520g expression worse overall survival than patients with low expression. (C-F) Overall survival curves obtained by Kaplan–Meier analysis with the log-rank test in patients with tumor recurrence (n = 45, C), no recurrence (n = 71, D), high serum CA-125 level (n = 108, E), and low serum CA-125 level (n = 8, F). High miR-520g expression indicated poorer patient survival with tumor recurrence or high serum CA-125 level.
