Identification of hsa_circ_0076957 and miR-4512-targeted COL19A1 as regulators in clopidogrel resistance among stable coronary heart disease patients through comprehensive circRNA and miRNA analysis.

Background: Clopidogrel resistance (CR) increases the risk of atherothrombotic events. Emerging evidence suggests that circRNAs may influence pharmacodynamic responses to clopidogrel.

Methods: A total of 25 CR and 25 non-clopidogrel resistance (NCR) patients were enrolled.

Transcriptome-wide map of N6-methyladenosine (m6A) profiling in coronary artery disease (CAD) with clopidogrel resistance.

Background: Clopidogrel resistance profoundly increases the risk of major cardiovascular events in coronary artery disease (CAD) patients. Here, we comprehensively analyse global m6A modification alterations in clopidogrel-resistant (CR) and non-CR patients.

Methods: After RNA isolation, the RNA transcriptome expression (lncRNA, circRNA, and mRNA) was analysed via RNA-seq, and m6A peaks were identified by MeRIP-seq.

DNA methylation profile in the whole blood of acute coronary syndrome patients with aspirin resistance.

Background: Aspirin resistance (AR) results in major adverse cardiovascular events, and DNA methylation might participate in the regulation of this pathological process.

Methods: In present study, a sum of 35 patients with AR and 35 non-AR (NAR) controls were enrolled. Samples from 5 AR and 5 NAR were evaluated in an 850 BeadChip DNA methylation assay, and another 30 AR versus 30 NAR were evaluated to validate the differentially methylated CpG loci (DML).
