TGM2 and rheumatoid arthritis: Thus, we focused on whether TGM2 mRNA m6A modification was responsible for the role of OS in RA‐FLS and compared differentially expressed genes in RA‐FLS after OS treatment based on our RNA‐seq data with the top 20 genes that were associated with TNFα‐mediated m6A modification in RA‐FLS based on a previous study.21
