Peroxynitrite-induced myocardial injury is mediated through matrix metalloproteinase-2.
OBJECTIVES Peroxynitrite (ONOO(-)) mediates in part both ischemia-reperfusion and pro-inflammatory cytokine-induced injury to the heart. As oxidants like ONOO(-) are known to activate matrix metalloproteinases (MMPs), we examined whether they play a role in the detrimental action of ONOO(-) in isolated perfused rat hearts. METHODS Hearts were isolated from Sprague-Dawley rats and perfused ret...
متن کاملMatrix Metalloproteinase 2 Contributes to Pancreatic Beta Cell Injury Induced by Oxidative Stress
OBJECTIVE To investigate the role of matrix metalloproteinase 2 (MMP2) in pancreatic beta cell injury induced by oxidative stress. METHODS Rat pancreatic beta cell line INS-1 cells were treated with advanced glycation end-products (AGE) to induce intracellular oxidative stress. Intracellular MMP2 expression and activity were determined by quantitative reverse transcription polymerase chain re...
متن کاملExpression of Matrix Metalloproteinase-2 and -9 in Meningioma
Background: Meningioma is one of the most common tumors of the central nervous system. It was shown that meningioma had up-regulated expression of Matrix Metalloproteinases (MMPs) that involved in cell growth, angiogenesis and metastasis. Objectives: The aim of the study was the assessment of serum MMP-2 and -9 levels in patients with different grades of meningioma. Materials & Me...
متن کاملSelective spatiotemporal induction of matrix metalloproteinase-2 and matrix metalloproteinase-9 transcription after myocardial infarction.
Myocardial remodeling after myocardial infarction (MI) is associated with increased levels of the matrix metalloproteinases (MMPs). Levels of two MMP species, MMP-2 and MMP-9, are increased after MI, and transgenic deletion of these MMPs attenuates post-MI left ventricular (LV) remodeling. This study characterized the spatiotemporal patterns of gene promoter induction for MMP-2 and MMP-9 after ...
متن کاملMatrix metalloproteinase-9-mediated tissue injury overrides the protective effect of matrix metalloproteinase-2 during colitis.
Matrix metalloproteinases (MMP) play an important role in pathogenesis of inflammatory bowel disease (IBD). Two known gelatinases, MMP-2 and MMP-9, are upregulated during IBD. Epithelial-derived MMP-9 is an important mediator of tissue injury in colitis, whereas MMP-2 protects against tissue damage and maintains gut barrier function. It has been suggested that developing strategies to block MMP...
