Background
N6-methyladenosine (m6A) is the most frequently occurring interior modification in eukaryotic messenger RNA (mRNA), and abnormal mRNA modifications can affect many biological processes. However, m6A’s effect on the metabolism of antiplatelet drugs for the prevention of ischemic stroke (IS) remains largely unclear.
Methods
We analyzed the m6A enzymes and m6A methylation in peripheral blood samples of IS patients with/without clopidogrel resistance (CR), and the peripheral blood and liver of rat models with/without CR. We also compared the effect of m6A methylation on the expression of the drug-metabolizing enzymes (CYP2C19 and CYP2C6v1) in CR and non-CR samples.
Results
Methyltransferase-like 3 (METTL3), an m6A enzyme, was highly expressed in the peripheral blood of patients with CR …
