Figure 4. The results of KEGG pathway enrichment. (A) The plot shows the top 20 significantly enriched KEGG pathways in response to OA treatment in MCF-7 cells. (B) The top 20 significantly enriched KEGG pathways were clustered into five pathway categories: cellular processes (red), environmental information processing (green yellow), human diseases (green), metabolism (blue) and organismal systems (purple).
