Box plots showing the differences in expression levels of MUC3 and PAI-1. Box plots (median, interquartile range and 95% CIs) show the differences in expression levels of MUC3 (A) and PAI-1 (B) comparing MUC3-silenced cells with control cells. (C) Differences in PAI-1 released into the media comparing MUC3-silenced cells with control cells. Gene-expression and protein levels are normalized to control (nonsilenced) cells (100%).
