(A) The concentrations of miR-18a in pancreatic cancer tissues. The differential expression of miR-18a in pancreatic cancer tissues was compared with that in normal tissues by a waterfall plot (panel A). The levels of miR-18a were significantly higher in cancer tissues (P=0.012). The upper and lower limits of the boxes and the lines inside the boxes indicate the 75th and 25th percentiles and the median, respectively. The upper and lower horizontal bars denote the 90th and 10th percentiles, respectively. (B) Concentrations of miR-18a in pancreatic cancer cell lines. The differential expression of miR-18a in pancreatic cancer cell lines was compared with that in a fibroblast cell line and normal tissues by a waterfall plot (panel B). In pancreatic cell lines, levels of miR-18a were significantly higher than those in fibroblasts and normal pancreatic tissues (P=0.015). ^*Normal means normal tissues, including the normal fibroblast cell line WI-38.
