Production of tissue inhibitors of matrix metalloproteinases (TIMPs), a family of secreted proteins with inhibitory actions on matrix metalloproteinases (MMPs), is up-regulated following nerve injuries and is suggested to have protective effects against MMP-mediated tissue damages. To clarify the extracellular signals involved in TIMP production in the brain, the effects of endothelins (ETs), a...

Tissue inhibitor of metalloproteinase-1 (TIMP-1) regulates intracellular signaling networks for inhibition of apoptosis. Tetraspanin (CD63), a cell surface binding partner for TIMP-1, was previously shown to regulate integrin-mediated survival pathways in the human breast epithelial cell line MCF10A. In the current study, we show that TIMP-1 expression induces phenotypic changes in cell morphol...

UNLABELLED Tissue inhibitor of metalloproteinase-1 (TIMP-1) regulates intracellular signaling networks for inhibition of apoptosis. Tetraspanin (CD63), a cell surface binding partner for TIMP-1, was previously shown to regulate integrin-mediated survival pathways in the human breast epithelial cell line MCF10A. In the current study, we show that TIMP-1 expression induces phenotypic changes in c...

BACKGROUND Previous studies have suggested plasma tissue inhibitor of metalloproteinases-1 (TIMP-1) as a stage independent prognostic marker in colorectal cancer (CRC) patients. The aim was to validate plasma TIMP-1 and serum carcino-embryonic antigen (CEA) levels as prognostic indicators in an independent population-based cohort of patients with CRC. PATIENTS AND METHODS During 2000-2003, pl...

Degradation of the extracellular basement membrane is implicated in atherosclerosis, restenosis after angioplasty, and intimal thickening of vein grafts. Upregulation of metalloproteinase (MMP)-2 and MMP-9 accompanies neointima formation in cholesterol-fed rabbits, in rat and pig models of angioplasty, and in organ cultures of human saphenous veins. MMPs are inhibited by binding to tissue inhib...

The tissue inhibitors of metalloproteinases 1-4 (TIMPs) have discrete regulatory roles in the activation of matrix metalloproteinase (MMP)-2 (gelatinase A), an important basement membrane-degrading MMP pivotal to tumor metastasis and angiogenesis. TIMP-2 binds to both the hemopexin C domain of progelatinase A and the active site of membrane type-1 (MT1) MMP. This trimeric complex presents the c...

Background: Increases in levels of matrix metalloproteinase (MMP) and tissue inhibitor of matrix metalloproteinase (TIMP) occur in acute aortic dissection (AAD); however, their association with prognosis in AAD remains largely unknown. We studied the use of MMP and TIMP in predicting long-term outcomes in medically controlled AAD patients. Methods: A total of 82 patients were enrolled (15 Stanf...

The family of tissue inhibitors of metalloproteinases (TIMPs) exhibits diverse physiological/biological functions including the inhibition of active matrix metalloproteinases, regulation of proMMP activation, cell growth, and the modulation of angiogenesis. TIMP-1 is a secreted protein that can be detected on the cell surface through its interaction with surface proteins. The diverse biological...

We monitored serum levels of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) before and during intravenously applied immunoglobulin (IVIG) therapy in 33 patients with chronic immune-mediated neuropathies and myopathies and 15 controls. Baseline MMP-2 and TIMP-2 serum levels were lower and MMP-9 and TIMP-1 serum levels higher in all patients compared to age-matched controls....

The fundamental event of cancer invasion and metastasis is the complicated interaction of cancer cells with host cells, in which event, a number of proteases and their inhibitors are involved. Matrix metalloproteinases are the potent proteases in degrading the basement membrane and extra cellular matrix and are inhibited by specific endogeneous inhibitors, tissue inhibitors of metalloproteinase...
