VCAM1 and atherosclerosis: Meta-analysis showed that relative to the control group, quercetin reduced aortic plaque area, adjusted lipids (lowered TC, TG, and LDL-C and raised HDL-C), downregulated adhesion factors (e.g., VCAM-1) and pro-inflammatory factors (e.g., IL-1β and IL-6), upregulated anti-inflammatory factor IL-10 and antioxidant enzymes (SOD, CAT) while decreasing MDA content, and regulated atherosclerosis-related targets (e.g., LXRα, SIRT1, and mTOR).
