Matrix metalloproteinase-9 (MMP-9) which is a member of matrix metalloproteinases family that normally remodel the extracellular matrix, has been shown to play an important role in both animal models of cerebral ischemia and human stroke. The expression of MMP-9 is elevated after cerebral ischemia which is involved in accelerating matrix degradation, disrupting the blood-brain barrier, increasi...
سابقه و هدف: ماتریکس متالوپروتئینازها (mmps یا matrix metalloproteinases) گروهی از آنزیم های تجزیه کننده ماتریکس خارج سلولی هستند که نقش مهمی در التهاب، آنژیوژنز (رگ زایی)، رشد و متاستاز سرطان دارند. ایزوسورباید، به عنوان یک دهنده نیتریک اکساید donor (no یا nitric oxide) دارویی رایج در درمان بیماری های قلبی است. به علاوه، اثر مهار کنندگی ایزوسورباید بر رشد و متاستاز تومور و آنژیوژنز در in vivo ...
BACKGROUND Matrix metalloproteinases (MMPs) are enzymes involved in the proteolytic degradation of extracellular matrix. They play an important role in several disease processes, such as inflammation, cancer, and atherosclerosis. METHODS AND RESULTS In this study, we have used the broad-spectrum MMP inhibitor CGS 27023A to develop the radioligand [123I]I-HO-CGS 27023A for in vivo imaging of M...
Wright, J. L., H. Tai, R. Wang, X. Wang, and A. Churg. Cigarette smoke upregulates pulmonary vascular matrix metalloproteinases via TNFsignaling. Am J Physiol Lung Cell Mol Physiol 292: L125–L133, 2007. First published August 11, 2006; doi:10.1152/ajplung.00539.2005.—Cigarette smoke exposure causes vascular remodeling and pulmonary hypertension by poorly understood mechanisms. To ascertain whet...
UNLABELLED Stem cells and biomaterials have been studied for therapeutic cardiac repair. Previous studies have shown the beneficial effects of platelet fibrin gel and cardiac stem cells when cotransplanted into rodent hearts with myocardial infarction (MI). We hypothesized that matrix metalloproteinases (MMPs) play an important role in such protection. Thus, the present study is designed to elu...
Tendon is mainly composed of collagen and an aqueous matrix of proteoglycans that are regulated by enzymes called matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). Although it is known that resistance exercise (RE) and sex influence tendon metabolism and mechanical properties, it is uncertain what structural and regulatory components contribute to these respo...
BACKGROUND Matrix metalloproteinases (MMPs) and their specific inhibitors (tissue inhibitor of metalloproteinases [TIMPs]), are involved in adipogenesis, angiogenesis and remodeling of extracellular matrix. MMPs and TIMPs have been shown to be associated with various diseases such as neurological disorders, malignancies and cardiovascular disease. MMPs and TIMPs are thought to play a major role...
Objectives: The goal of this research was to investigate whether metalloproteinases could be used as predictors preeclampsia (PE) during pregnancy. Materials and Methods: This case-control study included 100 pregnant women which they further grouped into PE control group (each composed 50 women). Both groups were subdivided according their gestational age (GA), using the 37th week gestation a d...
INTRODUCTION The role of matrix metalloproteinases (MMPs) in type 2 diabetes mellitus (DM) is not clear as increased activation of MMPs in the vasculature contrasts with decreased activity of MMPs in the kidneys, contributing to development of nephropathy. MATERIAL AND METHODS We measured serum MMP-2 and MMP-9 in 22 subjects with type 2 DM age (mean ± SD) 56.7 ±16.8 years, BMI 31.8 ±4.6 kg/m(...
Reversible modulation of cell-cell adhesion, cell-matrix adhesion, and proteolytic activity plays a critical role in remodeling of the neoplastic ovarian epithelium during metastasis, implicating cadherins, integrins, and proteinases in i.p. metastatic dissemination of epithelial ovarian carcinoma (EOC). Aberrant epithelial differentiation is an early event in ovarian carcinogenesis; thus, in c...
