*Results for miR-21-3p were ignored because only few target genes out of 78 were non-significantly enriched in two pathways (Neurotophin signaling pathway- 3 genes and Ubiquitin mediated pathway- 3 genes). Similarly, only 3 genes each out of 88 target genes for miR-184 were enriched (P > 0.05) in two pathways, Chronic myeloid leukemia and Prostate cancer and were ignored. The target genes for miR-un5, a newly identified miRNA in this study were not determined.
