Urate and MnTMPyP inhibition of 3-NT formation in the LPS/TNF-α-treated cardiomyocytes. Primary cultures of neonatal cardiomyocytes from wild-type mice were exposed to LPS/TNF-α for 48 h with or without cell-permeable urate or MnTMPyP. Coincubation of the cells with urate or MnTMPyP significantly inhibited LPS/TNF-α–induced 3-NT formation (A) and also significantly abolished LPS/TNF-α–induced cytotoxicity LDH, shown by the OD value at 490 nm (B). Quantitative analysis of 3-NT contents (band density) from three samples of each treatment is presented relative to actin content. Treatment groups that do not share the same letter were significantly different (P < 0.05).
