MUC16 and ovarian cancer: One study detected miR-93, miR-145, and miR-200c upregulation in exosomes derived from the serum of ovarian cancer patients, and the triple combination of serum exosomal miR-145 and miR-200c and serum CA125 was the most effective biomarker, with a sensitivity of 100% for the differential diagnosis of ovarian masses (benign ovarian cysts/borderline ovarian neoplasms versus ovarian cancers), indicating the strong diagnostic potential of miRNAs carried by exosomes.73
