  1. 22 out of 74 pathways containing host genes show a significant overrepresentation of targets within the pathway at a FDR of 10%. Host genes that were predicted targets of their own miRNA were removed from the count. Interestingly, the list of pathways contains many pathways crucial for development and signal transduction, or associated with neoplastic transformation.
