YTHDC1 and aortic aneurysm: Similarly, we obtained the RNA‐seq data of m6A regulators Ythdc1 and Mettl3 from RNA‐seq public database (GEO number: GSE140947), and found that mRNA expression of Ythdc1 and Mettl3 is also upregulated in VSMCs of human aortic aneurysm sample (Figure S9, Supporting Information).
