Effect of EGCG on IL-1β stimulated secretion of chemokines in human OA chondrocytes (a-b). Chondrocytes were pretreated for 2 h with EGCG (100 μM) and then stimulated or not stimulated with IL-1β (5 ng/ml) for 24 h. Values represent Mean ± SE of three different patients. # represents P < 0.05 Vs control; * P < 0.05 Vs IL-1β stimulated chondrocytes. BLC, B-lymphocyte chemoattractant; EGCG, epigallocatechin-3-gallate; ENA-78, epithelial neutrophil activating peptide-78; GCP-2, granulocyte chemotactic protein-2; GRO, growth-related oncogene; IL- interleukin; MCP, monocyte chemotactic protein; MDC, macrophage-derived chemokine; MIG, monokine induced by interferon-gamma; MIP, macrophage inflammatory protein; NAP-2, nucleosome assembly protein-2; RANTES, regulated upon activation normal T-cell expressed and secreted;IP-10,10 kDa interferon gamma-induced protein.
