Reactive air and nitrogen species (ROS and RNS, respectively) generate nitrotyrosine and activate latent resident myocardial matrix metalloproteinases (MMPs). treated with NaHS (an H2S donor, 30 mol/l in normal water) at 8 and 10 wk. The degrees of MMPs had been assessed by gelatin-gel zymography. The degrees of nitrotyrosine, tissues inhibitors of metalloproteinase (TIMPs), 1-integrin,… Continue reading Reactive air and nitrogen species (ROS and RNS, respectively) generate nitrotyrosine
