BMI1 and breast carcinoma: Interestingly, in our array data also we found significant reduction of stemness-related genes such as BMI-1, SOX-2, Twist-1, GLI-2, CXCR7 and ALDH1A3 after miR-195 overexpression thereby strongly implicating role of hsa- miR-195 in inhibiting breast cancer stem cell-like self-renewal
