 illustrate the significantly higher expression of miRNAs with low target gene expression. The scale of the y-axis (copy number) was chosen to facilitate visual comparison between groups and necessitated omission of up to three outliers from several graphs.  ######   Click here for file  ###### Additional data file 0  miRNAs were divided into those with significantly lower than expected target mRNA expression (labeled \'low\') and those with no detectable effect on the
