IFIT3 and systemic lupus erythematosus: By re-analyzing the published microarray data (32), we found EZH2 was significantly upregulated in monocytes from SLE patients (n = 58) as compared with healthy controls (n = 68) (Figure S1A) and positive correlations were found between the expression of EZH2 and CXCL10 or IFIT3 (Figures S1B, C), respectively.
