Enriched functions included iron ion binding, magnesium ion binding, calcium ion binding, zinc ion binding and copper ion binding. Key pathways involved carbon metabolism, the TCA cycle, oxidative phosphorylation, and extracellular matrix remodelling. PPI analysis highlighted hub proteins, including SOD2, NDUFS1, ACO2, IDH3A, MMP1, COL1A1, COL1A2, and LOX.
