The DNAm levels of CREB5 (cg11301281) were associated with clopidogrel resistance.

ABSTRACT:

Purpose

Clopidogrel resistance (CR) is mostly caused by interindividual variability of the platelet inhibition of clopidogrel, which may induce cardiovascular events. The aim of this research was to evaluate whether DNAm levels of CREB5 (cg01534253) are involved in CR among acute coronary syndrome (ACS) patients treated with clopidogrel.

Methods

72 patients(36 CR and 36 non-CR) who underwent ACS were included in this study. The VerifyNow P2Y12 assay was selected to evaluate residual platelet reactivity, and bisulfite pyrosequencing methods was used to examine DNA methylation levels on cg01534253. Secondly, CREB5 mRNA expression was analyzed via quantitative real-time PCR. Last, we employed logistic regression to test the interaction between genetic factors of CREB5 methylati
