Adiponectin Receptor 1 Single Nucleotide Polymorphism Is Highly Associated with Hypertriglyceridemia in Asian Male—A Novel Genetic Screening to Reduce Risk of Cerebrovascular Disease

摘要

Background: Adiponectin is involved in regulating both glucose and fatty acid. 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.
