ERBB2 and ovarian carcinoma: In addition, the down-regulation of miR-30c, miR-30d, miR-30e-3p, and miR-532-5p is associated with the overexpression of Her2/neu oncogene, whereas the overexpression of miR-30a-3p and miR-181d is associated with well-differentiated carcinomas (grade 1) compared with poorly differentiated carcinomas (grade 3), showing the diagnostic potential of multiple miRNA species for differential staging and grading of ovarian carcinoma.72
