Gene expression profiling demonstrates increased CXCR3-axis chemokine expression in the heart. Gene expression profiling showing differentially expressed genes in comparing (A) multiple samples of heart tissue to non-heart (lung/liver) tissue samples, (B) the heart to the liver, and (C) the heart to the lung. (D) Most differentially expressed genes detected when comparing the heart, liver, and lung. Normalized expression levels of (E) CXCL9, (F) CXCL11, and (G) CXCR3. n.s. = not significant; *** = p < 0.001; **** = p < 0.0001.
