MIR211 and rheumatoid arthritis: As demonstrated in this study that Mir204/211 suppress RA progression and play a protective role in RA, in our in vitro cell culture studies, we transfected CIA FLS with Mir204 mimics (or Mir204 inhibitor) and Mir211 mimics (or Mir211 inhibitor) simultaneously, to verify the important roles of Mir204/211 in RA.
