Summary of the numbers of differentially expressed genes that are significantly up- or downregulated compared to their expression in control cells. (A) Bar graph of genes significantly up- or down-regulated in PPARα-induced cells compared to their expression in control cells. (B) Differential expression volcano plot, in which red dots represent genes that are significantly upregulated and blue dots represent those that are significantly downregulated compared to their expression in control cells. The X-axis indicates the log2 FC of gene expression. The Y-axis indicates the statistical significance of differential expression as log10 (FDR). FC: fold change; FDR: false discovery rate.
