KEGG pathway enrichment analysis showed that target genes in the miRNA-mRNA regulatory network were enriched in 7 common pathways in the group of patients with steatosis and NASH: Hippo signaling pathway (KEGG: 04390), Axon guidance (KEGG: 04360), Wnt signaling pathway (KEGG: 04310), Breast cancer (KEGG: 05224), AMPK signaling pathway (KEGG: 04152), Dopaminergic synapse (KEGG: 04728), GABaergic synapse (KEGG: 04727) (Figure 4). Here, PRKAA2 is linked to breast carcinoma.
