Associations of the known adiponectin receptors 1 (ADIPOR1) single nucleotide polymorphism (SNP) with diabetes have been demonstrated while hypertriglyceridemia is frequently associated with cerebrovascular disease (CVD) among diabetes. Triglyceride metabolism was also reported to be different between genders and estrogen was observed to interfere with adiponectin effects via ADIPOR1. It seems important to investigate whether the ADIPOR1 SNP variants may be significant determinants in triglyceride metabolism and hence be a risk of CVD in specific gender. Methods: A survey was performed on random self-reported healthy subjects aged 35 and above with their biochemical data collected. Genotyping for ADIPOR1 SNP (rs1342387) was carried out using?TaqMan Genotyping Assays. Interviews were also conducted regarding stress, adverse diet behavior and exercise. Multivariable logistic regression analyses were performed to identify the strongest contributing variables. Findings: The ADIPOR1 minor allele carrier (T/T and T/C) had significantly (p?= 0.02) higher TG mean compared to homozygous (C/C) major alleles. TG difference was significantly higher in male (p?= 0.02) with a larger difference in mean, whereas the difference disappeared among female (p?= 0.32). Multivariate logistic regression analyses were performed by defining abnormal TG based on NCEP criteria of metabolic syndrome, and when all life style variables were entered in the model with ADIPOR1, only the ADIPOR1 inmale showed significant (p?= 0.03) and very high association with abnormal TG (Exp(β) 16.31). Discussion: The findings provide sample evidence of a relation between ADIPOR1 SNP minor allele carrier and high TG concentrations in male. The association of abnormal TG and ADIPOR1 is much stronger than that compared to life style. The implications of this survey may be further extend to identifying the genetic risk of abnormal TG at young age and reduce the CVD incidence by early intervention.展开更多

To investigate the contribution of the adiponectin genes and their receptors to T2DM, a case-control study was performed and 11 SNPs ofADIPOQ, ADIPOR1, and ADIPOR2 were genotyped in 985 T2DM and 1,050 control subjects, rs 16861194 （-11426 A〉G） in the putative promoter of ADIPOQ was associated with T2DM （P = 0.007; OR = 1.29, 95% CI 1.08-1.55）. None of the other 10 SNPs were associated with T2DM in this study, although rs2241766 and rs1501299 were reported to be associated with T2DM in previous Chinese studies. There was also no significant difference found from the ADIPOQ haplotype analysis, which contains rs 16861194. In addition, we also assessed potential gene-gene interactions in three genes and no interactions were found. In conclusion, our results supported the ADIPOQ gene as a possible risk factor for type 2 diabetes in Han Chinese population.展开更多
