Protective effect of Cyanidin on Myocardial infraction mice

ABSTRACT: Myocardial infarction (MI) is a worldwide disease with high morbidity and mortality and a major cause of chronic heart failure, seriously affecting patients' quality of life. Natural medicine has been used to cure or prevent cardiovascular disease for decades. As a natural flavonoid, Antocyanide has been used to treat many diseases due to its antioxidative, anti-inflammatory, and others. However, the molecular mechanism of Cyanidin (Cyn) in MI is not precise. As demonstrated by the result, after MI, some genes such as Fibronectin 1(Fn1) and Matrix metalloproteinases (MMP2/9) is highly overexpressed, and Cyn protects myocardial cell apoptosis by regulating these genes. These results were warranted by autodocking simulation.

Project description:This a model from the article: A theoretical model of type I collagen proteolysis by matrix metalloproteinase (MMP) 2 and membrane type 1 MMP in the presence of tissue inhibitor of metalloproteinase 2. Karagiannis ED, Popel AS. J Biol Chem 2004 Sep 10;279(37):39105-14 15252025 , Abstract: One well documented family of enzymes responsible for the proteolytic processes that occur in the extracellular matrix is the soluble and membrane-associated matrix metalloproteinases. Here we present the first theoretical model of the biochemical network describing the proteolysis of collagen I by matrix metalloproteinases 2 (MMP2) and membrane type 1 matrix metalloproteinases (MT1-MMP) in the presence of the tissue inhibitor of metalloproteinases 2 (TIMP2) in a bulk, cell-free, well stirred environment. The model can serve as a tool for describing quantitatively the activation of the MMP2 proenzyme (pro-MMP2), the ectodomain shedding of MT1-MMP, and the collagenolysis arising from both of the enzymes. We show that pro-MMP2 activation, a process that involves a trimer formation of the proenzyme with TIMP2 and MT1-MMP, is suppressed at high inhibitor levels and paradoxically attains maximum only at intermediate TIMP2 concentrations. We also calculate the conditions for which pro-MMP2 activation is maximal. Furthermore we demonstrate that the ectodomain shedding of MT1-MMP can serve as a mechanism controlling the MT1-MMP availability and therefore the pro-MMP2 activation. Finally the proteolytic synergism of MMP2 and MT1-MMP is introduced and described quantitatively. The model provides us a tool to determine the conditions under which the synergism is optimized. Our approach is the first step toward a more complete description of the proteolytic processes that occur in the extracellular matrix and include a wider spectrum of enzymes and substrates as well as naturally occurring or artificial inhibitors.
