Diagnostic and prognostic relevance of circulating exosomal miR-373, miR-200a, miR-200b and miR-200c in patients with epithelial ovarian cancer.

ABSTRACT: Exosomes are membrane vesicles that mediate intercellular communication by transporting their molecular cargo from cell to cell. We investigated whether serum levels of exosomal miR-373, miR-200a, miR-200b and miR-200c and circulating exosomes have diagnostic and prognostic relevance in a cohort of 163 epithelial ovarian cancer (EOC) patients using TaqMan MicroRNA assays and ELISA. The serum concentrations of exosomal miR-373 (p = 0.0001), miR-200a (p = 0.0001), miR-200b (p = 0.0001) and miR-200c (p = 0.028) were significantly higher in EOC patients than healthy women. The levels of miR-200a (p = 0.0001), miR-200b (p = 0.0001) and miR-200c (p = 0.019) could distinguish between malignant and benign ovarian tumors. While the levels of miR-373 and miR-200a were increased in all FIGO/lymph nod
