IGF2BP3 and rheumatoid arthritis: Molecular docking and in vitro experiment suggested that TP and IGF2BP3 had a high binding affinity and TP could decrease the mRNA expression of IGF2BP3 in PBMCs and MH7A.This research established a transcriptional map of m6A in RA PBMCs and displayed the hidden association between RNA methylation alterations and associated genes in RA.
