miR-221 regulates cell proliferation in CSCC. Expression level of miR-221 in cells after transfection with miR-221 mimics (a) and inhibitors (b), as detected by quantitative RT-PCR. miR-221 overexpression (c) or silencing (d) regulated cell viability in cells at 24, 48, and 72 h by MTT assay. Quantitative results of colony formation assay in A431 (e) and SCC13 (f) cells transfected with miR-221 inhibitor or mimic, respectively. * P < 0.05, compared with control
