Nur77 regulates lipid metabolism in zebrafish larvae. (A) Heatmaps of transcripts in lipid metabolism enrichment. Colors represent high (red), low (blue), or average (white) expression values based on Z-score-normalized fragments per kilobase per million mapped read (FPKM) values for each gene. The Z-score indicators are shown under each map. The fold change (log2) is shown on the right. (B) The validation of the expression levels of differentially expressed genes by qRT-PCR analysis in the categories of lipid metabolism (n = 3). (C) Disturbed cholesterol biosynthesis. Blocks represent transcript-encoded enzymes. Green blocks represent downregulated genes, and black blocks represent unchanged genes. (D) The whole-body cholesterol (TC) contents of WT and nur77−/− zebrafish (n = 3). (E) The whole-body total triglyceride (TG) contents of WT and nur77−/− zebrafish. Results are represented as means with standard errors (n = 3); *p < 0.05, ***p < 0.001, ****p < 0.0001 by t-test.
