JAHA:预测氢氯噻嗪血压反应性的新型标志物

2017-12-31 MedSci MedSci原创

虽然氢氯噻嗪(HCTZ)是一线抗高血压药物,但是在接受HCTZ治疗的高血压患者中仅有不到一半达到了理想的血压水平,因此,寻找能预测对HCTZ起反应的生物标志物迫在眉睫。本研究的目的旨在通过代谢组学、基因组学和脂类组学的方法寻找与HCTZ血压反应相关的新的生物标志物。首先,本研究对最近研究发现与HCTZ血压反应性相关的13中代谢产物进行了pathway分析,分析结果显示鞘脂类代谢途径是与HCTZ血压

虽然氢氯噻嗪(HCTZ)是一线抗高血压药物,但是在接受HCTZ治疗的高血压患者中仅有不到一半达到了理想的血压水平,因此,寻找能预测对HCTZ起反应的生物标志物迫在眉睫。本研究的目的旨在通过代谢组学、基因组学和脂类组学的方法寻找与HCTZ血压反应相关的新的生物标志物。

首先,本研究对最近研究发现与HCTZ血压反应性相关的13中代谢产物进行了pathway分析,分析结果显示鞘脂类代谢途径是与HCTZ血压反应性相关度最高的代谢通路(P=5.8E‐05)。之后,又对鞘脂类代谢途径中的14个基因的78个突变进行检测分析,发现SPTLC3基因的一个单核苷酸多态性rs6078905可以作为HCTZ血压反应性的新的标志物(n=228)。此外,研究发现rs6078905能显着影响4种鞘磷脂的基线水平(N24:2, N24:3, N16:1和N22:1),而其中N24:2与HCTZ的血压反应性呈明显相关性。

本研究结果揭示了氢氯噻嗪血压反应性潜在的药理和基因靶点,SPTLC3基因可作为预测HTCZ血压反应性的新型标志物。
