Fig. 2 — Overexpression of miR-149 inhibited cell proliferation, colony formation and promoted apoptosis in NB cells. a, b The expression of miR-149 was measured in SK-N-BE(2)C and SK-N-SH cells transfected with miR-149 or miR-NC by qRT-PCR. c, d Cell proliferation was detected in SK-N-BE(2)C and SK-N-SH cells transfected with miR-149 or miR-NC at different time points by MTT. e, f The numbers of colonies were analyzed in SK-N-BE(2)C and SK-N-SH cells transfected with miR-149 or miR-NC by colony formation assay. g, h Cell apoptosis was examined in SK-N-BE(2)C and SK-N-SH cells transfected with miR-149 or miR-NC by flow cytometry. *P < 0.05, **P < 0.01, compared with miR-NC group
