Superoxide dismutase
proteinSOD catalyzes superoxide dismutation; reduced activity or expression reflects failed antioxidant defense in atherosclerotic inflammation and endothelial injury.
Pathway placement
Cascade stepPlaque inflammation
Confidencemedium
RationaleAntioxidant enzyme; altered activity reflects oxidative stress in inflamed plaque and dysfunctional endothelium.
Also acts inEndothelial activation/erosion
Druggability
Not assessed (no mapped human gene target).
