VEGFA and rheumatoid arthritis: Figure 3 displays the outcomes of KEGG enrichment analysis on DEPs, indicating their primary enrichment in specific pathways: Complement and coagulation cascades (3 proteins), Focal adhesion (3 proteins), Rap1 signaling pathway (3 proteins), VEGF signaling pathway (2 proteins), Ras signaling pathway (3 proteins), Calcium signaling pathway (3 proteins), EGFR tyrosine kinase inhibitor resistance (2 proteins), MAPK signaling pathway (3 proteins), and Rheumatoid arthritis (2 proteins).
