Liver transcriptome analyses of WT zebrafish and Ehhadh-knockout zebrafish (Ehhadh^−/−). A: KEGG pathway enrichment analysis of DEG from WT and Ehhadh^−/−. B: Network interaction analysis between DEG corresponding proteins. C: DEG heat map analysis related to fatty acid metabolism. D: Flow chart of Ehhadh regulating DHA synthesis through the PPARα and insulin signaling pathways. The blue arrow indicates a significant decrease in expression. DEG, differentially expressed gene; Ehhadh, enoyl-CoA hydratase/3-hydroxyacyl CoA dehydrogenase.
