Furthermore, the expression of Ki-67, a well-known proliferative marker, was dramatically increased in miR-96 overexpressing-MCF-7 and -ZR-75-30 breast cancer cells compared with that in NC transfected cells (Figure 1E), suggesting that upregulation of miR-96 specifically promotes the proliferation of breast cancer cells. Here, MKI67 is linked to breast carcinoma.
