KEGG pathway analysis showed that the predicted target genes related to miR-98, miR-375, and miR-335 were involved in cytokine-cytokine receptor interaction, calcium signaling pathway, glycan structures - biosynthesis 1, melanoma, and Wnt signaling pathway (Fig. 3c), whereas the predicted target genes of miR-199a-5p and miR-22 were related to MAPK signaling pathway, chronic myeloid leukemia, melanogenesis, insulin signaling pathway, and prostate cancer (Fig. 3d). The gene discussed is INS; the disease is prostate cancer.
