Effect of miR-32 expression on growth and migration in breast cancer cells. a, b QRT-PCR of miR-32 expression in mimic/inhibitor or NC transfected MCF-7 cells. U6 was used as an internal control. c, d MTT analysis of MCF-7 growth following transfection with miR-32 mimic/inhibitor or NC. MiR-32 mimic promotes cell proliferation and inhibitor suppresses cell growth. e, f Wound-healing assay showing that gain of miR-32 promotes cell migration and loss of miR-32 suppresses cell migration. Each assay was repeated three times. *P < 0.05
