RENBP and brain ischemia: The enriched results of BP including “blood circulation”, “response to lipopolysaccharide”, “response to wounding”, and “positive regulation of cell migration”, etc. The enriched KEGG pathways including AGE-RAGE, HIF-1, and cAMP signaling pathways, etc. By analyzing the results of GO and KEGG enrichment, we found that these processes were closely related to key genes associated with cerebral ischemia.
