miR-133b is down-regulated in GC cells and in GC tissues. (A) The expression level of miR-133b in the four GC cell lines (HGC-27, MGC-803, SGC-7901 and MKN-45) and a human gastric epithelium cell line (GES). Data are shown as mean + s.d. (n = 3); * indicates P-value <0.05; ** indicates P-value <0.01. (B) The relative expression of miR-133b in 100 pairs of GC tissues (C) and adjacent non-neoplastic tissues (N). (C) Normalized expression of miR-133b in 100 pairs of GC and adjacent normal tissues. (D) The correlation of miR-133b expression with venous invasion. (E) The correlation of miR-133b expression with tumor stages.
