The network also indicated that the target genes of GAS5, lnc0640, and lnc5150 were dual specificity phosphatase 4 (DUSP4), arrestin beta 2 (ARRB2), and ribosomal protein S6 kinase A5 (RPS6KA5), respectively, indicating that the contribution of GAS5, lnc0640, and lnc5150 to the pathogenesis of SLE may be through the MAPK signaling pathway (Figures S6 and S7, Supplementary Materials). The gene discussed is DUSP4; the disease is systemic lupus erythematosus.
