Figure 4. The key components of the MAPK signaling pathway were activated in FoxA2-/- mice. (A, B) IHC and Western blotting analysis of low FoxA2 and high p-ERK1/2, CREB1 and RAS expression in FoxA2-/- mice; © The heatmap shows the activation of key genes in the MAPK signaling pathway in ICC patients. These genes were selected from the KEGG database for MAPK signaling pathways (
