Figure 1From: Microarray analysis of gene expression in lupusExemplary gene sequences that cluster with PRKR and OAS3. Hierarchical clustering was performed on the total study population to determine genes that cluster with PRKR and OAS3. A visual demonstration of the expression of a selection from those genes, comprising a partial IFN signature, is shown. Data are shown from a subset of SLE samples tested (n = 14) and from rheumatoid arthritis (RA) (n = 11), juvenile chronic arthritis (JCA) (n = 2), and control samples (n = 8). Relative expression compared with an internal control ranged from approximately -0.5 (bright green) to 0.5 (bright red).Back to article page
