Figure 2. Gene networks of activator protein 1 (AP-1) transcription factors in the HCC subtype with liver progenitor cell signature. Upregulated and downregulated genes in the HCC subtype, with progenitor signature, are indicated in red and green, respectively. Genes in gray color are not on the list but are associated with the regulated genes. Gray lines and arrows represent the direction of transcriptional regulation, and plus and minus signs indicate positive and negative regulation of gene expression. Purple lines represent known physical interactions between connected genes.
