Differential analysis found 36 of 110 LLPS-related genes (RPL23A, UBC, NPM1, FBN1, APP,DDX3X, FYN, SUMO3, HNRNPA1, MYC, MAP1LC3B, XPO1, BRD4, ABL1,SPOP, KPNA2, TARDBP, FUS, NCK1, IPO5, EIF4EBP2, LBR, RARA, LCP2, DAZAP1, TNRC6B, HSPB2, TAF15, GATA2, GATA3, PIAS2, LAT, DYRK3, AR, CCNT1 and GRAP2) to be significantly differently expressed in RA patients (Figures 2A, B; Table 1), and the network between these LLPS-related genes is shown in Figure 2C. This evidence concerns the gene KPNA2 and rheumatoid arthritis.
