The top 10 highly expressed miRNAs were involved in miRNAs in cancer, axon guidance, MAPK (mitogen-activated protein kinase) signaling pathway, pathways in cancer, enrichment pathways of differentially expressed miRNAs of target genes, including FoxO signaling pathway, dopaminergic synapse, Wnt signaling pathway, MAPK signaling pathway, and the Hippo signaling pathway. The gene discussed is WNK2; the disease is cancer.
