Abstract
OBJECTIVE To determine the relationship between the R577X polymorphism of the α-actinin-3 (ACTN3), which may play a role in the individual differences observed in the effects of exercise on health benefits and antiatherogenic markers (i.e., high-density lipoprotein cholesterol [HDL-C] and adiponectin) in athletes. METHODS Seventy-six male rugby players (mean age 19.8 years) were enrolled in this study. Genomic DNA was extracted from peripheral blood samples, and restriction fragment length polymorphism-polymerase chain reactions were conducted to assess ACTN3 genotypes. Body mass index (BMI), waist circumference, serum lipids including HDL-C, and adiponectin levels were measured. Current smoking and alcohol intake habits were evaluated with a questionnaire. All of the parameters were compared between 2 groups displaying frequently observed genotypes: one group consisting of patients having either the R/R or R/X genotype and a second group with the X/X genotype. RESULTS The frequency of the X allele was 0.55 and the distribution of the genotypes was 35.5% (n = 27) for X/X, 39.5% (n = 30) for R/X, and 25.0% (n = 19) for R/R. Serum HDL-C and adiponectin levels were significantly higher in X/X genotype compared to the R/R or R/X genotype (HDL-C 1.6 ± 0.3 [SD] vs. 1.4 ± 0.2 mmol/L; P<.01, adiponectin 8.8 ± 2.6 vs. 6.9 ± 2.3 μg/mL; P<.01), even after adjustments for confounders (P<.01). CONCLUSION There may be a relationship between the ACTN3 genotype and HDL-C and adiponectin levels in rugby players. This may be useful information when determining the individual responses of antiatherogenic markers to exercise. ABBREVIATIONS ACTN3 = α-actinin-3 BMI = body mass index CVD = cardiovascular disease HDL-C = high-density lipoprotein cholesterol LDL-C = low-density lipoprotein cholesterol R = arginine (R) at amino acid position 577 of the ACTN3 protein TC = total cholesterol TG = triglyceride X = truncation at amino acid position 577 of the ACTN3 protein.

Abstract
Insulin resistance (IR) is a major risk for the development of type 2 diabetes (T2D). Numerous studies have been conducted to determine the relationship of ADIPOQ G276T with IR and blood glucose, but the results are conflicting. We conducted a meta-analysis in this work to further investigate such an association. Published works were retrieved from PubMed and Embase databases. A pooled standardized mean difference (SMD) with 95 % confidence interval (CI) was calculated under a dominant model using a random effect model. Twenty-five studies involving 7,480 subjects were included in the meta-analysis. A significant association of G276T polymorphism with homeostasis model assessment insulin resistance index (HOMA-IR) was observed after excluding studies with obvious heterogeneity by performing influence analysis (SMD = -0. 08, 95 % CI -0.15 to -0.01, p = 0.019) and Galbraith plot analysis (SMD = -0.08, 95 % CI -0.14 to -0.02, p = 0.005). In the subgroup analysis, Asians with TG/TT genotypes were found to have a significantly decreased degree of HOMA-IR (SMD = -0.13, 95 % CI -0.20 to -0.07, p < 0.001). The association of G276T with IR or blood glucose for the subgroups (obese, male, and T2D) was also significant. However, the results may not be reliable for small sample sizes. The current meta-analysis suggested that the G276T polymorphism may genetically affect IR using HOMA-IR as an index, and the effect of this polymorphism on IR particularly exists in Asians.

Abstract
BACKGROUND Circulating adipokines may be associated with breast cancer risk. Genetic variants governing adipokines and adipokine receptors may also predict risk, but their effect on breast adipokine concentrations is unknown. METHODS We conducted a cross-sectional analysis of functional SNPs in 5 adipokine genes [adiponectin, leptin (LEP), and their receptors] among 85 cancer-free women who were undergoing reduction mammoplasty. RESULTS In multivariable-adjusted regression models, compared with the common GG genotype, the AA genotype of the LEP A19G SNP was associated with 27% lower plasma adiponectin [ratio, 0.73; 95% confidence interval (CI), 0.54-0.98] and leptin (ratio, 0.73; 95% CI, 0.55-0.96). Women with the AG genotype of LEP A19G had 39% lower breast leptin (ratio, 0.61; 95% CI, 0.39-0.97) compared with those with the GG genotype. No associations were observed for SNPs in the remaining genes. CONCLUSIONS Genetic variation in LEP may alter endogenous adipokine concentrations in circulation and in breast tissues. IMPACT These preliminary findings may support the hypothesis that genetic variation in adipokine genes modifies circulating adipokine concentrations and possibly leptin concentrations in local breast tissues, which may be associated with breast cancer risk.

Abstract
OBJECTIVE The aim of this study was to investigate the link between circulating adiponectin levels and peak oxygen uptake and/or physical activity in Japanese. METHODS A total of 528 subjects (188 men and 340 women) were enrolled in this cross-sectional study. Circulating adiponectin levels, physical activity measured by tri-axial accelerometers, peak oxygen uptake and metabolic risk parameters were evaluated. We also assessed anthropometric factors, blood pressure, blood examinations and energy intake. RESULTS Circulating adiponectin levels were 6.7 ± 3.0 μg/mL in men and 11.0 ± 4.9 μg/mL in women. Circulating adiponectin levels were positively correlated with physical fitness after adjusting for age, physical activity evaluated by Σ [metabolic equivalents × h per week (METs h/w)], cigarette smoking habit and energy intake in both sexes. However, these associations were attenuated further after adjusting for body mass index including other confounding factors, especially in men. However, circulating adiponectin levels were not associated with physical activity in either sex. CONCLUSION Circulating adiponectin levels were associated with peak oxygen uptake rather than physical activity.

Abstract
Adiponectin is an adipokine involved in the regulation of body metabolism and immune response. Circulating levels and/or activity of adiponectin were reported to influence susceptibility to several diseases, including type 2 diabetes mellitus, cardiovascular disease, and metabolic syndrome. In this study, serum adiponectin levels and the association of adiponectin gene (ADIPQO) single-nucleotide polymorphism (G276T SNP) with hypertension in type 2 diabetic patients were examined. Type 2 diabetic patients (n = 449) were recruited and divided into two groups, normotensive (n = 199) and hypertensive (n = 250). Results demonstrated that serum adiponectin levels were significantly higher in normotensive subjects compared with hypertensive subjects (P < .05). When these results were compared according to gender, only female hypertensive diabetic patients showed significantly higher levels of adiponectin (P < .05). In addition, no significant difference in the genotypes and alleles frequencies of ADIPQO G276T SNP was observed between the two groups (P > .05). In conclusion, high circulating levels of adiponectin were found to be associated with hypertension only in type 2 diabetic female patients which might indicate a gender preference.

Abstract
OBJECTIVE Results from the published studies on the association of adiponectin gene (ADIPOQ) polymorphisms with blood lipids and blood pressure are conflicting. We investigated the association of three ADIPOQ polymorphisms, +45 T > G (rs2241766), +276 G > T (rs1501299) and -11377 C > G (rs266729), with these traits in this meta-analysis. RESEARCH DESIGN AND METHODS We included 35 studies in this meta-analysis. Dominant models were used for this meta-analysis. RESULTS We did not detect a significant association of the -11377 C > G polymorphism with blood lipids or blood pressure (P > 0·05). The association of the +45 T > G polymorphism with blood lipids and blood pressure was, similarly, not significant (P > 0·05). The meta-analysis suggested a significant overall association of the +276 G > T polymorphism with lower levels of total cholesterol: weighted mean difference (WMD) = -0·10, 95% confidence interval (CI, -0·17, -0·03), P = 0·005, P(heterogeneity) = 0·04. This association was marginally significant in East Asians and East Asians with type 2 diabetes: WMD = -0·10, 95% CI (-0·20, 0·00), P = 0·05, P(heterogeneity) = 0·002, and WMD = -0·09, 95% CI (-0·18, -0·00), P = 0·05, P(heterogeneity) = 0·80, respectively. After exclusion of a study that was the source of heterogeneity, the association was significant in overall populations and marginally significant in East Asians: WMD= -0·06, 95% CI (-0·11, -0·01), P = 0·01, P(heterogeneity) = 0·98, and WMD = -0·06, 95% CI (-0·12, 0·00), P = 0·07, P(heterogeneity) = 0·83, respectively. However, none of these associations were significant after Bonferroni correction (significant threshold: P < 0·003). CONCLUSIONS Our meta-analysis does not suggest any association of the three ADIPOQ polymorphisms with blood lipids and blood pressure.

Abstract
Adipokines are important for regulation body metabolism and immune response. Many studies have shown that variants in adipokines genes play a role in age-associated diseases. In this study, we investigated the contribution of rs266729 (-11377G/C), rs2241766 (+45T/G), and rs1501299 (+276 G/T) SNPs of adiponectin gene (ADIPQO) and rs7799039 (-2548C/A) SNP of leptin (LEP) gene to human longevity phenotype in Jordanian population. Polymorphisms were genotyped in 110 randomly selected elderly subjects (>85 years old) with mean age of 90.2 years, and 120 young control subjects (range from 20 to 50 years) with mean age of 32.0 years. No significant differences were detected in the genotype and allele frequencies of examined gene variants between the two groups (p > 0.05). However, when gender was considered, genotypes and alleles frequencies of rs1501299 SNP in ADIPOQ gene and rs7799039 in LEP gene were significantly associated with longevity in men (p < 0.02) but not in women (p > 0.05). Thus, ADIPOQ and LEP genes polymorphisms might play a gender-specific role in the pathway to men's longevity.

Abstract
According to recent genome-wide association studies, a number of single nucleotide polymorphisms is reported to be associated with diseases or several clinical markers. Among them, adiponectin (ADIPOQ) and perilipin (PLIN) polymorphisms are major factors of obesity. However, the association between lifestyle factor, these polymorphisms and obesity-related clinical markers in Japanese is not well researched. Therefore, the aim of present study is to investigate the association between lifestyle factor, polymorphisms of lipid metabolic genes, and clinical markers in 148 middle-aged Japanese males. The study revealed that ADIPOQ 45 T>G and ADIPOQ 276 G>T genotypes were significantly associated with triglyceride, total cholesterol, hemoglobin A1c (HbA1c) in blood and body mass index (BMI). PLIN4 11482 G>A and hormone sensitive lipase (LIPE)-60 C>G genotypes were respectively associated with BMI and serum triglyceride. Not only genetic factors but also lifestyle factors influence several clinical markers. The BMI of subjects who like sweets and have the GG allele in ADIPOQ 276 G>T was higher than that of subjects who don't like sweets. The habit of eating fruits and fish affected low-density lipoprotein-cholesterol of the GT allele and HbA1c of the TT allele in ADIPOQ 276 G>T. Those findings indicate improvement and conservation of lifestyle depending on genetic predisposition in ADIPOQ, PLIN and LIPE should be encouraged.

Abstract
PURPOSE Single nucleotide polymorphisms (SNPs) of the adiponectin gene have been reported to be associated with insulin resistance and the prevalence of type-2 diabetes. We investigated the SNPs of adiponectin in non-alcoholic fatty liver disease (NAFLD) patients. METHODS One hundred nineteen patients histologically diagnosed as having NAFLD and 115 control subjects were examined. Adiponectin SNP sites were investigated at +45 of exon 2 and at +276 of intron 2; these sites have been thought to be associated with diabetes or insulin resistance. RESULTS Regarding the +276 SNP, the frequency of G/G tended to be higher in NAFLD patients than in controls, but not significantly. Among females only, however, the G/G frequency was significantly higher in NAFLD patients. As for the +45 SNP, in the severe fibrosis group, the frequency of G/G homozygotes was significantly higher than that in the mild fibrosis group, and G/G homozygotes of the +45 SNP proved by multivariate analysis to be an independent factor in severe fibrosis. In NAFLD patients with adiponectin +45 G/G, homeostasis model assessment-insulin resistance was significantly higher than in NAFLD patients without adiponectin +45 G/G. CONCLUSION Adiponectin SNPs were found to be associated with the progression of liver fibrosis and insulin resistance, suggesting that adiponectin SNPs might play roles in the occurrence and progression of NAFLD.
