1. Ectopic expression of miR-187 in MCF7 cells results in increased migration, invasion, and anchorage-independent colony formation.
Ectopic expression of miR-187 in MCF7 cells results in increased migration, invasion, and anchorage-independent colony formation. A and B, MTT cell viability assay showing response of miR-187 expressing MCF7 cells to antiestrogens. Graph is representative of 1 of 3 independent repeats (± SD). No statistically significant change in response to either drug was noted (P = for tamoxifen and P = for fulvestrant). C, scratch wound assay showing that MCF7 cells expressing miR-187 display greater migratory potential than parental MCF7 cells or those infected with a NTC vector for 1 of 3 independent repeats ± SD; P = relative to NTC cells, Student t test based on the slope of each line. D, soft-agar colony formation assay showing that expression of miR-187 in MCF7 cells increases anchorage-independent growth compared with control cell lines for 1 of 3 independent repeats, ±SD. E, spheroid invasion assay showing that spheroids formed by MCF7 cells expressing miR-187 show increased invasion into collagen as compared with control cell lines. F, Western blot analysis of MMP13 in cell lysates with β-actin as a loading control.
