mir-126* and its complement mir-126, which are encoded by intron 7 of the egfl7 gene, have been reported to impair cancer progression through signalling pathways that control tumour cell proliferation, migration, invasion, and survival in a wide variety of cancers [37], [38], [39], [40], [41], [42], [43], especially in breast cancer [44], [45]. Here, EGFL7 is linked to breast carcinoma.
