In this study, we found that the average expression levels of ENST00000619282, LINC01006 and MIR22HG in the PBMCs of patients with RA were significantly higher than that in the PBMCs of healthy controls (Fig. 7A–C), whereas the expression of MAPKAPK5‐AS1, LINC01189 and DSCR9 was significantly lower in patients with RA as compared with healthy controls. Here, LINC01189 is linked to rheumatoid arthritis.
