MIR23B and benign neoplasm: MIR23B mRNA expression was significantly lower in the ovarian carcinomas and borderline tumors than in the normal ovarian tissues and benign tumors (Fig. 1a, p < 0.05), and there were significant differences in expression among ages (Fig. 1b, p < 0.05) and pathological subtypes (mucinous vs. other types, Fig. 1d, p < 0.05).
