Patients with clinical atherosclerosis showed increased levels of SDF1 (2.7 ± 0.9 ng/mL vs. 2.3 ± 0.5 ng/mL, p < 0.001), MMP12 (501 [282–768] pg/mL vs. 358.5 [241.5–553.5] pg/mL, p = 0.002) and CRP (0.24 [0.13–1] mg/dL vs. 0.12 [0.07–0.31] mg/dL, p < 0.001). The gene discussed is CXCL12; the disease is atherosclerosis.
