Aim: Aberrant global DNA methylation is involved in the development of several diseases, including cardiovascular disease (CVD). We investigated whether the methylation of long interspersed nuclear element-1 (LINE-1) in leukocytes is associated with dyslipidemia, a major risk factor for CVD, in the Japanese general population.

Methods: We conducted a cross-sectional study consisting of 420 Japanese subjects (187 men and 233 women) without a clinical history of cancer, stroke, or ischemic heart disease. LINE-1 DNA methylation levels in leukocytes were measured using a pyrosequencing method.

Results: Significantly higher odds ratios (ORs) for hypermethylation were observed in the high LDL cholesterol and high LDL/HDL ratio groups than the corresponding normal group (high LDLC group: OR, 1.88; 95% confidence interval [CI], 1.20–2.96, high LDL/HDL ratio group: OR, 1.90; 95% CI, 1.20–3.01). Subjects with 2 or more lipid abnormalities had significantly higher ORs for hypermethylation than those with no lipid abnormality (OR, 2.31; 95% CI, 1.11–4.82).

Conclusion: LINE-1 DNA hypermethylation in leukocytes was associated with CVD risk profiles: high LDLC, high LDL/HDL ratio, and the degree of abnormal lipid metabolism.
