Multi-dimensional scaling plots comparing miRNA expression levels in different tissue. A. Multi-dimensional scaling plots comparing miRNA expression levels in CCA tissue versus matched distal normal tissue (Distal) and non-CCA normal liver tissue (Non-CCA). When compared to non-CCA normal tissue, tumor tissue grouped together but fewer differences where observed when comparing tumor tissue to its matched distal normal tissue. B. Comparison of miRNA expression in the two control samples, D-NT and N-NT. Multi-dimensional scaling plot of comparison between raw counts obtained from D-NT and N-NT. A clear differentiation between the two samples can be seen.
