Gene ontology enrichment analysis of 21 differentially expressed proteins (DEPs) in abdominal aortic aneurysm. (a) Biological process annotation results showed that the DEPs were significantly enriched in leukocyte migration, positive regulation of cell adhesion, etc. (b) Cellular component annotation displayed that the DEPs were significantly enriched on the external side of plasma membrane. (c) Molecular function annotation showed that the DEPs were enriched in receptor regulatory and ligand activities, cytokine activity, cell adhesion molecule binding, cytokine receptor binding, etc.
