MiR-148b inhibits cell proliferation in vitro. (A), MTT proliferation assay in MGC-803, SGC-7901 and BGC-823. (B), Growth curves by counting cell number in MGC-803, SGC-7901 and BGC-823. (C), MTT proliferation assay in AGS. (D), Anchorage-independent growth assay in SGC-7901 cells. The colonies were counted (top) and captured (bottom). (E), The results of cell cycle analysis in MGC-803 and SGC-7901 cells. All results were reproducible in three independent experiments. *, P < 0.05; **, P < 0.01.
