The extracellular matrix plays a critical role in neural crest (NC) cell migration. In this study, we characterize the contribution of the novel GPI-linked matrix metalloproteinase (MMP) zebrafish mmp17b. Mmp17b is expressed post-gastrulation in the developing NC. Morpholino inactivation of mmp17b function, or chemical inhibition of MMP activity results in aberrant NC cell migration with minima...

Cerebrovascular disease is one of the leading causes of death in the world, and about one-fourth of cerebrovasculardeaths are due to ruptured cerebral aneurysms (CA). Hence it is important to find a way to reduce aneurysmformation and its subsequent morbidity and mortality. Proteolytic activity capable of lysing gelatin hasbeen shown to be increased in aneurysm tissue and expression of plasmin,...

T-lymphocyte migration into tissues requires focal degradation of the basement membrane. In this study, we show that transient adherence to fibronectin induces the production of activated forms of matrix metalloproteinase-2 (MMP-2) and MMP-9, as well as downregulation of tissue inhibitor of metalloproteinase-2 (TIMP-2) by T-cell lines. MMP-2 activation was likely achieved by inducing a coordina...

conclusions our results suggest that tetracyclines dose-dependently inhibit mmp-9 activity, and among the common clinical tetracyclines, minocycline provides the most potent inhibition of excess mmp-9 activity and its consequences. materials and methods an mmp-9-rich culture medium of u-937 cells was used as the source of the enzyme. serial dilutions of 5, 20, 100, 200, and 500 µm of each drug ...

Volume 4 • Issue 2 • 1000e112 Adv Tech Biol Med ISSN: 2379-1764 ATBM, an open access journal Matrix metalloproteinase (MMPs) are a family of zinc dependent endopeptidases that play a significant role in cancer as well as in numerous other diseases [1]. It degrades the extracellular matrix (ECM) components and controlled remodeling of ECM is essential for invasion, metastasis and growth of vario...

AIMS Aortic valve diseases are characterized by pathological remodelling of valvular tissue but the cellular and molecular effectors involved in these processes are not well known. The role of matrix metalloproteinase (MMP)-2, MMP-9, MMP-3, MMP-7, and tissue inhibitor of matrix metalloproteinase (TIMP)-1 and TIMP-2 are investigated here. METHODS AND RESULTS Histological analysis of pathologic...

Background: The most malignant form of infiltrating astrocytoma, glioblastoma multiforme (GBM), is one of the most aggressive human cancers. Foretinib diminished GBM cell invasion by downregulating the expression of matrix metalloproteinase 2 (MMP2). The study aimed to examine the anti-tumor activity of foretinib and to test its effect on MMP2 expression in T98 cells. Materials and methods: T9...

This study shows that the expression of the extracellular matrix metalloproteinase inducer (EMMPRIN) in oral squamous cell carcinoma cells (SCC) depends upon activation of the Src Family kinaseFyn; and that EMMPRIN and β6 form a complex that requires active Fyn and the full length β6 integrin cytoplasmic domain. Fyn is also important for matrix remodeling as it regulates both matrix type 1 meta...

The balance of endogenous angiogenic factors in the body is responsible for the homeostatic control of angiogenesis during normal physiological circumstances, with the disruption of this fragile balance leading to pathologic angiogenic events such as those involved in cancer progression. This review focuses regulation of the pro-angiogenic factors membrane type-1 matrix metalloproteinase (MT1-M...
