MIAT and rheumatoid arthritis: The results of cell experiments showed that miR-204-5p was poorly expressed in RA-FLS and MIAT was highly expressed in RA-FLS, which was consistent with the prediction of ceRNA regulation mechanism, and the expression of miR-204-5p was concentration-dependent up-regulated and MIAT expression was concentration-dependent down-regulated after HDW treatment of RA-FLS.
