IGF2BP3 and rheumatoid arthritis: Given the higher m6A level in RA, we analyzed the diagnostic value and biological role of 19 m6A regulators in RA, which found that IGF2BP3 not only has important diagnostic significance for RA, but is also closely related to cell proliferation and M1 macrophage polarization.20 Therefore, we focused on the mechanism by which IGF2BP3 affected the progression of RA.
