Figure S1METTL3 expression in the aorta of mice with atherosclerosis (AS).A.Relative mRNA expression levels of METTL3 in control, AS, AS+siNC, and AS+si‐METTL3 groups; B. Representative Western blot images and quantification of METTL3 protein levels, normalized to β‐actin, across the same groups. The gene discussed is METTL3; the disease is atherosclerosis.
