Regarding the therapeutic role of miRNAs in ovarian cancer, Gu et al. [69] reported that three miRNAs (hsa-miR-146a, hsa-miR-148a and hsa-miR-545) are predominantly expressed in patients with wild-type BRCA1/2 ovarian cancers who may benefit from platinum-based chemotherapy. This evidence concerns the gene BRCA1 and ovarian carcinoma.
