Recently, minor alleles of two strongly linked polymorphisms in the PPARA gene, rs4253728 G>A and rs4823613 A>G, were related to decreased CYP3A4 expression and activity. We studied whether they were associated with the cholesterol-lowering effect of simvastatin.
MATERIALS & METHODS: We identified 123 incident users with cholesterol measurements before and after starting statin therapy in a prospective population-based cohort study. Associations between PPARA polymorphisms and change in total and low-density lipoprotein (LDL)-cholesterol levels were analyzed using linear regression.
The minor G allele of the rs4823613 A>G polymorphism was associated with a 0.258 mmol/l (95% CI: -0.470 to -0.046) and a 0.294 mmol/l (95% CI: -0.495 to -0.093) larger reduction in total and LDL-cholesterol, respectively, after starting simvastatin therapy. Results were similar for the rs4253728 G>A polymorphism.
The minor alleles of the PPARA rs4253728 and rs4823613 polymorphisms are associated with a better total and LDL-cholesterol-lowering response to simvastatin, possibly through influence on CYP3A4.
最近,PPARA 基因中两个紧密连锁的多态性的次要等位基因 rs4253728 G>A 和 rs4823613 A>G,与 CYP3A4 表达和活性降低有关。我们研究了它们是否与辛伐他汀的降胆固醇作用有关。
我们在一项前瞻性基于人群的队列研究中,确定了 123 名开始他汀类药物治疗前和治疗后胆固醇测量的新发病例患者。使用线性回归分析 PPARA 多态性与总胆固醇和低密度脂蛋白(LDL)-胆固醇水平变化之间的关系。
rs4823613 A>G 多态性的次要 G 等位基因与辛伐他汀治疗开始后总胆固醇和 LDL-胆固醇分别降低 0.258 mmol/l(95%CI:-0.470 至 -0.046)和 0.294 mmol/l(95%CI:-0.495 至 -0.093)相关。rs4253728 G>A 多态性的结果相似。
PPARA rs4253728 和 rs4823613 多态性的次要等位基因与辛伐他汀的总胆固醇和 LDL-胆固醇降低反应更好相关,可能通过对 CYP3A4 的影响。
