Of particular interest are the miR-200, miR-29, and miR-30 families, which all have been linked to the mesenchymal phenotype, invasion, or metastasis in breast cancer [28,29], and which all have predicted target sites in the ADAM12-L 3′UTR, but not in the ADAM12-S 3′UTR. This evidence concerns the gene ADAM12 and breast cancer.
