Abstract
Metabolic syndrome (MetS) is characterised by increased blood pressure, elevated fasting blood glucose, increased triglycerides, reduced high-density lipoprotein cholesterol and central obesity. The cause is multifactorial and includes gene-environment interactions. ADIPOQ gene has been linked to its development, but results have been conflicting. The gene is expressed in adipose tissue and it encodes a protein that is involved with metabolic and hormonal processes. The objective of this study was to investigate the association between the genetic variants of the ADIPOQ gene (+ 45T > G and + 276G > T) with MetS among a relocated indigenous Temiar subtribe community in Malaysia. This cross-sectional study investigated 123 relocated Temiar volunteers in Kelantan. Modified NCEP ATP III criteria were used to diagnose MetS. DNA was extracted from peripheral blood and genotyped for ADIPOQ + 45T > G and + 276G > T polymorphisms using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) technique. Associations between ADIPOQ + 45T > G (rs2241766) and + 276G > T (rs1501299) polymorphisms and MetS were investigated using a binary logistic regression analysis and calculations of odds ratios (ORs). Compared to the wild-type gene, the OR for the occurrence of MetS with heterozygous (T/G) was 87.2 and with homozygous (G/G) genotype was 26.5 at the ADIPOQ + 45T > G locus. Similarly, the OR was 38.2 for heterozygous (G/T) and 19.7 for homozygous (T/T) at the ADIPOQ + 276G > T locus. The genetic polymorphisms at the ADIPOQ + 45T > G (rs2241766) and + 276G > T (rs1501299) loci increased the odds for development of MetS among the relocated Temiar subtribe. The results have significant implications for primary prevention strategies to reduce risks for MetS.

Abstract
Objective: The goal of this study was to investigate the relationship between the adiponectin (apM1) gene rs266729 locus C>G polymorphism and ischemic stroke susceptibility by meta-analysis. Methods: The electronic databases of Pubmed, EM Base, Web of Science, Google scholar, CBM and CNKI were systematic searched with the text words of "stroke", "apM1 gene", "ADIPOQ", "ACDC" "GBP 28" "Acrp30" and "polymorphism". The relationship between apM1 gene rs266729 locus C>G polymorphism and ischemic stroke susceptibility was demonstrated by odds ratio (OR) and corresponding 95% confidence interval (95% CI). Data was pooled by random or fixed effect model according to the heterogeneity evaluation across the included studies. Publication bias was evaluated by Begg's funnel plot and Egger's line regression test. All the data was analyzed by ReviewMan 5.1 and Stata10.0 SE software. Results: Seven case-control studies were included in the meta-analysis. The relationship between apM1 gene rs266729 locus C>G polymorphism and ischemic stroke susceptibility was evaluated separated through the hypothesis of dominant (GG+CG vs CC), recessive (GG vs CC+CG) and homologous (GG vvs CC) genetic model. In a dominant genetic model, the combined OR = 1.20 (95% CI: 1.08 similar to 1.34) by fixed effect model. For a recessive genetic model, the OR was pooled by random effect model with point estimated of 1.26 and its 95% confidence interval of 0.78 similar to 2.05. In the aspect of homologous genetic model, the OR = 1.35 (95% CI: 0.82 similar to 2.22), through random effect model because of significant publication bias among the included studies. Conclusion: In the condition of dominant genetic model, people carrying G allele may have increased risk of developing ischemic stroke.
