Adiponectin gene SNP 276G �� T, nutrient intakes, and cardiovascular disease risk in Korean type 2 DM patients

Single nucleotide polymorphism (SNP) in adiponectin gene has been associated with insulin resistance, diabetes, and cardiovascular disease (CVD). This study was performed to investigate the association of SNP 276G→T at adiponectin gene with CVD risk factors in Korean type 2 diabetes mellitus (DM) patients. The subjects were 351 type 2 DM patients visited a DM clinic in Seoul, and the patients with known CVD were excluded. The adiponectin SNP 276G→T was analyzed and dietary intakes were assessed by a Food Frequency Questionnaire. The prevalence of G/G, G/T, and T/T genotype was 47.6%, 43.3%, and 9.1%, respectively. Male subjects with T/T genotype showed significantly lower level of adiponectin and HDL-cholesterol and significantly higher C-reactive protein (CRP) level compared to G/G and G/T genotypes. In G/G genotype, protein intake was negatively correlated to body weight, BMI, and waist circumference, and there were positive correlation between carbohydrate intake and BMI, waist-hip ratio, and ApoB/apoA-1 ratio in G/T genotype. However, in T/T genotype, there was no significant association between macronutrient intakes and anthropometric and hematological values. In conclusion, CVD risk would be high in type 2 DM patients with T/T genotype, and the association of macronutrient intakes with anthropometric and hematologic factors was different among the three adiponectin genotypes. These results may imply the need for different dietary management regime according to adiponectin genotype to lower CVD complications in Korean type 2 DM patients.     

Perilipin polymorphism interacts with dietary carbohydrates to modulate anthropometric traits in hispanics of Caribbean origin

Perilipin (PLIN) is the major protein surrounding lipid droplets in adipocytes and regulates adipocyte metabolism by modulating the interaction between lipases and triacylglycerol stores. Associations between PLIN gene polymorphisms and obesity risk have been described, but interactions with dietary macronutrients require further attention. We examined whether dietary macronutrients (e.g. carbohydrates and fats) modulated the associations of the common PLIN 11482G > A (rs894160) single nucleotide polymorphism with obesity. We studied a population-based sample of Caribbean-origin Hispanics (n = 920, aged 45-74 y) living in the Boston area. Obesity measures (waist and hip circumference, BMI) did not differ between GG subjects and carriers of the A allele (GA and AA). In multivariate linear regression models, we found a significant interaction between complex carbohydrate intake as a continuous variable and PLIN 11482 G > A genotype for waist circumference (P = 0.002). By dichotomizing complex carbohydrate intake, we found significantly different effects across PLIN 11482G > A genotypes. When complex carbohydrate intake was <144 g/d, waist circumference was larger in PLIN 11482G > A carriers (P = 0.024). Conversely, when complex carbohydrate intake was >/=144 g/d, waist and hip circumferences were less in PLIN 11482G > A carriers (P < 0.05). These interactions were not found for simple sugars or total carbohydrates. We identified a significant gene-diet interaction associated with obesity at the PLIN locus. In subjects with higher complex carbohydrate intake, the minor allele was protective against obesity, whereas in subjects with lower carbohydrate intake, the minor allele was associated with increased obesity. These interactions may be relevant to dietary management of obesity.     

The single nucleotide polymorphism upstream of insulin-induced gene 2 ( INSIG2) is associated with the prevalence of hypercholesterolaemia, but not with obesity, in Japanese American women

Insulin-induced gene 2 (insig-2) protein is known to play important roles in cholesterol and TAG metabolism both in vivo and in vitro. One particularly interesting single nucleotide polymorphism (SNP), rs7566605, located 10 kb upstream of INSIG2 was reported to have the strongest association with obesity among 86 604 SNP, while the relationship with dyslipidaemia is uncertain. Eight hundred and eighty-five Japanese Americans (347 men and 538 women) and 378 Japanese (182 men and 196 women) were enrolled, and the rs7566605 SNP, which is consistent with either G or C, was determined. We investigated the association between the rs7566605 SNP and the prevalence of hypercholesterolaemia or hypertriacylglycerolaemia, or obesity parameters, as assessed by BMI, waist girth and percentage body fat. There were no significant differences in BMI, waist girth and percentage body fat according to the genotype in each of the four groups, which was divided by population and sex. The prevalence of hypercholesterolaemia was significantly different between the genotypes in Japanese American female subjects (GG, 62.2 %; GC, 57.1 %; CC, 42.1 %; P = 0.021), but not in the other subjects. In Japanese American women, the subjects with the CC genotype had a 0.43-fold decreased risk (95 % CI 0.24, 0.80) for hypercholesterolaemia compared with the GG genotype after adjustment for age, percentage body fat, smoking status and hormone replacement therapy. The CC genotype of the rs7566605 SNP is suggested to be a protective genetic factor against the progression of hypercholesterolaemia on a high-fat diet, especially in Japanese female subjects.

The Association of Body Mass Index and Waist Circumference with Blood Pressure Depends on Age and Gender: A Study of 10,928 Non-Smoking Adults in the Greek EPIC Cohort

Body mass index (BMI) and waist circumference are independently associated with blood pressure, but the dependence of these associations on gender and age has not been clarified. We investigated the associations of BMI and waist circumference with systolic (SBP) and diastolic (DBP) blood pressure and assessed possible interactions with gender and age. Data concerning blood pressure and anthropometric variables were collected at enrollment in a cohort study from 10,928 non-smoking adults, all over Greece, who have never received antihypertensive treatment. Multiple regression-derived standardized coefficients were estimated to compare effects among variables. Among men, waist circumference appears more important than BMI in the prediction of SBP (standardized coefficients 2.26 vs. 1.52 mmHg/SD), and to a lesser extent DBP. In contrast, among women, BMI is more important than waist circumference, in the prediction of SBP (standardized coefficients 3.97 vs. 1.56 mmHg/ SD) and to a lesser extent DBP. The different effects of BMI and waist circumference on blood pressure by gender are evident among older individuals (> 55 years); among younger individuals BMI and waist circumference have comparable effects in both genders. Among younger individuals, BMI and waist circumference are independent and equally important predictors of SBP and DBP in both genders, whereas among older individuals waist circumference is the dominant predictor of blood pressure among men and BMI is the dominant predictor of blood pressure among women. Associations are more evident with respect to SBP than DBP.
