Figure 4. Specific knockout of Mettl3 in hepatocytes results in downregulating lipid metabolism-related genes. (A) Principal component analysis (PCA) plot showing reproducibility among the replicates of each group. (B) Volcano plot showing the differential expression of protein-coding genes in the GSE176113 dataset. (C–H) Gene set enrichment analysis (GSEA) plot of enrichment of indicated signatures in Mettl3 HKO livers using the C5 MSigDB database.
