Heatmap of miRNA expression in mucosal colonic biopsies of UC patient and control cohorts.

<p>Unsupervised hierarchical clustering of all samples based on the log2 expression values of the top 20 most variable miRNAs. Samples are shown in the columns and miRNAs in the rows. The boxes in color indicate the log2 intensities of the miRNAs, with blue indicating low expression and yellow indicating high expression.
