Abstract:
The objective of this study was to investigate whether the combination of miR-224-5p, miR-199-3p, and let-7d-3p is a suitable diagnostic panel for endometriosis. Twenty-five women with endometriosis (case) and twenty-five women without any sign of endometriosis (controls) were included. Peripheral blood specimens were collected from all these women who were a proper candidate for laparoscopy before surgery. Total RNA was isolated to synthesize complementary DNA. Expression of miR-199b-3p, miR-224-5p, and let-7d-3p was analyzed by RT-qPCR. To estimate the performance of the identified miRNAs for endometriosis diagnosis, we performed ROC curves analysis. There was an upregulation of miRNAs 199b-3p (P value < 0.001) and down-regulation of 224-5p (P value < 0.001) and miRNA let-7d-3p (P value < 0.05) in women with endometriosis compared to non-endometriosis women. The diagnostic accuracy of miRNAs 199b-3p, 224-5p, and let-7d-3p was measured by AUC which was 0.843 (sensitivity = 96% and specificity = 80%), 0.914 (sensitivity = 84% and specificity = 80%), and 0.696 (sensitivity = 80% and specificity = 56%) for miRNAs 199b-3p, 224-5p, and let-7d-3p, respectively. In combination, they showed the highest accuracy with the AUC 0.992 (sensitivity = 96% and specificity = 100%). In conclusion(s) the levels of miRNAs 199b-3p, 224-5p, and Let-7d-3p in plasma are potential diagnostic biomarkers for endometriosis patients.
