Effects of iNOS inhibitors on the adiponectin-induced production of matrix metalloproteinases MMPs in osteoarthritis (OA) chondrocytes. A nonselective NOS inhibitor (L-NMMA, 2 mM) and a specific iNOS inhibitor (L-NIL, 50 μM) significantly enhanced MMP-1 (A), MMP-3 (B), and MMP-13 (C) expressions induced by adiponectin (30 μg/ml). Experiments were performed on four samples in duplicates. The histogram with error bars represents the mean and the standard error of the mean. †P < 0.05 by Mann-Whitney test.
