CD14 and systemic lupus erythematosus: After combining DEGs and DMGs expressed in CD14+ monocytes, 77 hypomethylated-highly expressed genes and 116 hypermethylated-low expressed genes were identified by overlapping three microarrays (GSE71370, GSE38351, and GSE131989) in RA (Figure 8A), whereas 252 hypomethylated-highly expressed genes and 140 hypermethylated-low expressed genes were identified by overlapping three microarrays (GSE46907, GSE38351, and GSE59250) in SLE (Figure 8B).
