We examined the relationship between RhoA expression in the PBMCs of the SLE group with four well-characterized type I IFN inducible genes: OAS1, CXCL10, IFIT3 and MX1, and observed a significant positive correlation with RhoA expression (Figs. 1B–E). This evidence concerns the gene CXCL10 and systemic lupus erythematosus.
