According to the RNA‐seq data obtained from the GSE89408 dataset, we found that five m6A regulators, including IGF2BP3, YTHDF2, HNRNPC, METTL3 and RBM15, have the most relative relationship with ICAM2 in RA synovial tissues (Figure S9A). The gene discussed is YTHDF2; the disease is rheumatoid arthritis.
