Wen et al. (Wen et al., 2020a; Wen et al., 2020b) found that in PBMCs of RA patients, the levels of seven lncRNAs (MIR22HG, DSCR9, LINC01189, MAPKAPK5-AS1, ENST00000619282, C5orf17 and LINC01006) were significantly changed compared with the control. This evidence concerns the gene MIR22HG and rheumatoid arthritis.
