Figure 1 Representative RNase protection assay (RPA) (A) and relative messenger ribonucleic acid (mRNA) levels (B) of chemokines in mononuclear blood cells (MNCs) from 20 patients with chronic heart failure (CHF) and 10 healthy control subjects (CTR). Horizontal lines indicate mean values. GAPDH = glyceraldehyde-3-phosphate dehydrogenase; I-309 = inducible-309; IL-8 = interleukin-8; IP-10 = interferon inducible protein-10; MCP-1 = monocyte chemoattractant protein-1; MIP-1 = macrophage inflammatory protein-1; MIP-1ß = macrophage inflammatory protein-1ß; RANTES = regulated upon activation, normally T cell expressed and secreted; rpL32 = ribosomal protein L32.
