Figure 2. Expression profiling data for miR-140 and miR-193b in breast cancer and normal tissue. miR-140 expression was significantly upregulated in breast cancer tissue (miR-140 expression in breast cancer tissue was ∼14 fold that of normal tissue; p = 0.015) whereas miR-193b expression was not significantly different from that of normal tissue (p = 0.242). The first two columns from left are the mean of normal breast tissue samples, the last two columns are the mean of tumor breast tissue samples and the error bars indicate the 95% confidence intervals (CI).
