【 摘 要 】

Bilirubin, an antioxidant in the blood, plays a role in protection from atherosclerosis. The level of bilirubin is highly correlated to the incidence of coronary artery disease (CAD). Unconjugated bilirubin is conjugated with glucuronic acid through the reaction of uridine 5′-diphosphate-glucuronosyl transferase 1A1 (UGT1A1). The interactions of CAD and the variations in the coding regions of the UGT1A1 gene have never been evaluated. The purpose of this study was to analyze the influence of the UGT1A1 variant on the incidence of CAD. There were 135 participants in this study: 61 in the experimental group, who had CAD, and 74 in the control group, who did not have CAD. The blood samples from all 135 participants were collected and assayed to clarify the relationship between bilirubin and CAD. The assay of the polymerase chain reaction and the sequence of the UGT1A1 gene were examined to find the gene’s polymorphisms. The bilirubin levels for the participants in the control group were significantly higher than for the patients in the CAD group. Although the concentration of bilirubin in the UGT1A1 variant was higher than the wild type for the patients in the CAD group, there was no significant difference in the polymorphism of UGT1A1 between the patients in the CAD group and the participants in the control group.
