FOSL1 and rheumatoid arthritis: The effect of the m6A modification on FOSL1 mRNA stability is suggested by various findings, including a recent analysis of the m6A methylome in response to triptolide in rheumatoid arthritis, in which FOSL1 mRNA methylation and abundance is strongly affected, along with IGF2BP3, encoding of the insulin-like growth factor 2 mRNA-binding protein 3 [40].
