MiR-874, miR-143-3p, miR-876-5 and miR-6775-3p have also been shown to contribute to the down-regulation of MAGE gene expression in cancer cells [74–77] and vice versa, MAGEH1 can suppress breast cancer metastases through upregulating mir-200a/b expression [78]. The gene discussed is MAGEH1; the disease is breast cancer.
