Changes of Content of Matrix Metalloproteinases and Their Tissue Expression in Various Types of Atherosclerotic Plaques

Abstract: Резюме Цель исследования. Изучить диагностически значимые для стабильных и нестабильных атеросклеротических бляшек (АСБ) разных типов показатели активности матриксных металлопротеиназ-ММП-3, ММП-7, ММП-9 в гомогенатах и тканевую экспрессию ММП-2, ММП-9 и коллагена 4-го типа. Материалы и методы. В исследование включены 54 мужчины с коронарным атеросклерозом без острого коронарного синдрома, у которых в ходе операции коронарного шунтирования проведена эндартерэктомия из коронарной артерии. В полученных образцах … Show more

“…The positive association between MMP-9 and CVF levels indicated that MMP-9 induces the abnormal metabolism of myocardial collagen by promoting the degradation of normal collagen, increase the abnormal myocardial matrix components, increase CVF, and induce remodeling of atrial myocardial structures. This results in a susceptible environment for AF and consequently promoting the development and maintenance of AF [19,20]. These nding were in agreement with the results of previous studies.…”

“…Increased activity of MMP-7 and MMP-9 was observed in unstable plaques, the highest tissue expression of MMP-9 was found in plaques of lipid type compared with plaques of necrotic and inflammatory-erosive types [10]. In addition, MMP-7 could contribute to plaque instability in carotid The MMP-1, MMP-2, MMP-3, MMP-7, and MMP-9 expression was found in endothelial cells and vascular smooth muscle cells (VSMCs), while MMP-12 showed expression in VSMCs and fibroblasts [21].…”

“…In late atherosclerotic lesions, the expression of MMP-9 is increased and can induce plaque destruction [ 28 ]. Volkov et al [ 29 ] also confirmed that the level of MMP-9 was significantly increased in unstable fatty plaques, necrotic plaques and inflammatory erosive plaques. These studies suggest that VCAM-1 and MMP-9 play important early warning roles in unstable plaques.…”
