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 Here, ERBB2 is linked to carcinoma.
