To test whether miR-200c functionally impacted tumor promoting phenotypes, as miR-200c does in human BC cells26, Met-1 TripZ-EV and Met-1 TripZ-200c cells were evaluated for proliferation (Fig. 2a), growth on soft agar (Fig. 2b), migration (Supplementary Fig. 2a), and invasion (Fig. 2c). This evidence concerns the gene GZMM and breast cancer.
