Abstract:
BACKGROUND:Coronary heart disease (CHD) is primarily caused by atherosclerosis of coronary arteries. It is largely an inflammatory disease of the vascular wall. The inflammation is related to DNA methylation. Angiopoietin-like protein 2 (ANGPTL2) has various functions in several chronic inflammatory diseases. Macrophage-derived ANGPTL2 was reported to accelerate CHD development. It is reported that DNA hypomethylation in the promoter region of ANGPTL2 gene was associated with acute coronary syndrome (ACS), a type of CHD. Our objective was to explore the correlation between promoter methylation of the ANGPTL2 gene and CHD, and to investigate the association between methylation status and clinical characteristics of CHD patients. METHODS:Firstly, we collected 122 CHD patients and 58 non-CHD participants from Han Chinese population and purified the peripheral blood DNA. The purified DNA was subjected to bisulfite modification. After bisulfite conversion, the target DNA locus was amplified using polymerase chain reaction (PCR), and the PCR products were measured by pyrosequencing. Finally, the methylation level was calculated according to the sequencing result, and the data were analyzed using xx software. RESULTS:CHD patients had a relatively lower methylation levels (P50: 7.67% [P25: 6.22%, P75: 10.43%]) in the ANGPTL2 promoter region than did controls (P50: 8.25% [P25: 5.46%, P75: 17.98%], P = 0.001), indicating an association between ANGPTL2 promoter methylation and CHD (OR: 0.890; 95% CI, 0.832-0.953; adjusted P = 0.001). A breakdown analysis by gender showed that ANGPTL2 promoter methylation was associated with CHD in females (adjusted P = 0.002) but not in males (adjusted P = 0.404). We found no correlation between gene methylation and other clinical characteristics. CONCLUSIONS:The present work provides evidence to support an association between ANGPTL2 promoter DNA methylation status and the risk profile of CHD in females. Our data indicated that in females, promoter DNA hypomethylation of the ANGPTL2 gene is associated with an increased risk of CHD.
