| 摘要: | Objective: Previous investigations have revealed an association between the ABO locus/blood group and total cholesterol and inflammatory biomarker levels. We aimed to test the statistical association of ABO locus variants with lipid profiles and levels of thirteen inflammatory markers in a Taiwanese population.
Methods and results: A sample population of 617 Taiwanese subjects was enrolled. Five ABO gene region polymorphisms were selected and genotyped. After adjusting for clinical covariates and inflammatory marker levels, the genetic-inferred ABO blood group genotypes were associated with sE-selectin level (P = 3.5 x 10(-36)). Significantly higher total and low-density lipoprotein cholesterol (LDL-C) levels were noted in individuals with blood group A (P = 7.2 x 10(-4) and P = 7.3 x 10(-4), respectively). Interestingly, after adjusting for sE-selectin level, significantly lower high-density lipoprotein cholesterol (HDL-C) level as well as higher triglyceride (TG) level and ratio of triglyceride to HDL-C (TG/HDL-C ratio) were noted in individuals with blood group A comparing to non-A individuals (P = 0.009, P = 0.004 and P = 0.001, respectively); these associations were also observed in the group A male subjects (P = 0.027, P = 0.001, and P = 0.002, respectively). Mediation analysis further revealed a suppression effect of sE-selectin level on the association between genetic-inferred ABO blood group genotypes and TG/HDL-C ratio in total participants (P = 1.18 x 10(-6)) and in males (P = 5.99 x 10(-5)).
Conclusion: Genetic variants at the ABO locus independently affect sE-selectin level in Taiwanese subjects, while the association of ABO locus variants with TG/HDL-C ratio is suppressed by sE-selectin level in Taiwanese males. These results provided further evidence for the mechanism in the association of ABO blood groups with atherosclerotic cardiovascular diseases. (C) 2013 Elsevier Ireland Ltd. All rights reserved. |
