The positive rate (96.30%) and high positive rate (85.19%) of MRPL15 expression in epithelial ovarian cancer tissues were significantly higher than those in epithelial borderline tumor tissues (55.33% and 40.00%, respectively), epithelial benign tumor tissues (41.67% and 16.67%, respectively), and normal ovarian tissues (30.00% and 00.00%, respectively) (all p < 0.05; Table 4). Here, MRPL15 is linked to benign epithelial neoplasm.
