ZBTB12 DNA methylation is associated with coagulation- and inflammation-related blood cell parameters: findings from the Moli-family cohort.

Background Zinc finger and BTB domain-containing protein 12 (ZBTB12) is a predicted transcription factor with potential role in hematopoietic development. Recent evidence linked low methylation level of ZBTB12 exon1 to myocardial infarction (MI) risk. However, the role of ZBTB12 in the pathogenesis of MI and cardiovascular disease in general is not yet clarified. We investigated the relation between ZBTB12 methylation and several blood parameters related to cardio-cerebrovascular risk in an Italian family-based cohort. Results ZBTB12 methylation was analyzed on white blood cells from the Moli-family cohort using the Sequenom EpiTYPER MassARRAY (Agena). A total of 13 CpG Sequenom units were analyzed in the small CpG island located in the only translated ZBTB12 exon. Principal component analysis (PCA) was performed to identify groups of CpG units with similar methylation estimates. Linear mixed effect regressions showed a positive association between methylation of ZBTB12 Factor 2 (including CpG units 8, 9–10, 16, 21) and TNF-ɑ stimulated procoagulant activity, a measure of procoagulant and inflammatory potential of blood cells. In addition, we also found a negative association between methylation of ZBTB12 Factor 1 (mainly characterized by CpG units 1, 3–4, 5, 11, and 26) and white blood cell and granulocyte counts. An in silico prediction analysis identified granulopoiesis- and hematopoiesis-specific transcription factors to potentially bind DNA sequences encompassing CpG1, CpG3–4, and CpG11. Conclusions ZBTB12 hypomethylation is linked to shorter TNF-ɑ stimulated whole blood coagulation time and increased WBC and granulocyte counts, further elucidating the possible link between ZBTB12 methylation and cardiovascular disease risk

Relation between pulmonary function and 10-year risk for cardiovascular disease among healthy men and women in Italy: the Moli-sani Project.

BACKGROUND: Pulmonary dysfunction could influence the onset and the evolution of cardiovascular disorders. This study evaluated whether pulmonary dysfunction based on spirometry, plethysmography and carbon monoxide diffusion test is associated with the estimated risk of cardiovascular disease in 10 years. DESIGN: We performed a cross-sectional general population-based cohort study. METHODS: The Moli-sani Project is a population-based cohort study of subjects aged ≥35 years, randomly recruited from the general population in Italy. Cardiovascular risk in 10 years was predicted by the CUORE score which provides an estimate of the probability of a first coronary or cerebrovascular event in the next 10 years, based on a risk equation derived from Italian cohorts. Out of 12,933 subjects with high-quality flow/volume manoeuvre, 8,132 subjects had suitable plethysmography and 3,422 carbon monoxide diffusion (carbon monoxide alveolar diffusion test [DLCO]). RESULTS: In multivariate analyses, reduced pulmonary function expressed by forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and total lung capacity (TLC) were inversely associated with CUORE score both in men and in women, independently of other risk factors such as age, height, smoking habits, total cigarettes exposure (pack-years), pulmonary disease, body mass index, social status and physical activity. In contrast, there was no association between FEV1/FVC ratio, residual volume, DLCO and CUORE risk score. CONCLUSIONS: In both genders from an adult general Italian population, pulmonary function decline is associated with increased cardiovascular risk. These results suggest that pulmonary monitoring could be useful to more accurately predict cardiovascular risk

Total dietary antioxidant capacity and lung function in an Italian population: a favorable role in premenopausal/never smoker women

BACKGROUND/OBJECTIVES: Antioxidant-rich foods may favorably influence lung function. We examined possible associations between the total dietary antioxidant capacity (TAC) and pulmonary function in a healthy Italian population. SUBJECTS/METHODS: Until May 2009, 22,300 persons were randomly recruited from the general population in the Moli-sani project. A sample only including healthy women (5824) and men (5848) was analyzed. TAC was measured in foods by three different assays and the ferric reducing-antioxidant power (FRAP) assay was selected as the better indicator of dietary TAC. The European Investigation into Cancer and Nutrition Food Frequency Questionnaire was used for dietary assessment. The association between quintiles of dietary FRAP and pulmonary indexes was assessed using analysis of variance separately for men and women. RESULTS: After adjustment for confounders, women in the highest quintile of FRAP intake had +39 ml forced expiratory volume in the first second (FEV(1)) and +54 ml forced vital capacity, compared with those in the lowest quintile (P for trend ≤0.006). Stratified analysis showed that this relationship only occurred in women who were premenopausal/never smokers. In this subgroup, the observed effect of higher FRAP intake on FEV(1) was equivalent to an improvement in pulmonary age of 3.3 years. In men, all significant associations between pulmonary function and TAC were lost after adjustment for confounding. CONCLUSIONS: Dietary TAC may have a favorable role in respiratory health, particularly in premenopausal/never smoker women
