Reduction of miR-106b suppressed laryngeal carcinoma cell proliferation. (A) Expression levels of miR-106b in laryngeal carcinoma cells 48 h after As-miR-106b and miR-106b treatment. (B) MTT assay displayed that cells treated with As-miR-106b proliferated at a significantly lower rate than control groups after transfection. (C) After 48 h treatment, cells were harvested and performed by cell cycle assay. Data are expressed as the mean ± SD of 3 independent experiments. * P < 0.05 compared with control group.
