We found that cell proliferation, migration and invasion capacity was lower and apoptosis level was higher in cells co-transfected by Stmn1 siRNA and miR-101 inhibitor than that transfected by miR-101 inhibitor (Figure 12), displaying that miR-101 low expression-mediated the promotion of cell growth and metastasis was partially attenuated by knockdown of Stmn1. Taken together, these results indicate that miR-101 executes functions in breast cancer cells partially by targeting Stmn1. Here, STMN1 is linked to breast cancer.
