BACKGROUND Excessive stimulation of Gq protein-coupled receptors by cognate vasoconstrictor agonists induces a variety of cardiovascular processes, including hypertension and hypertrophy. Here, we report that matrix metalloproteinase-7 (MMP-7) and a disintegrin and metalloproteinase-12 (ADAM-12) form a novel signaling axis in these processes. METHODS AND RESULTS In functional studies, we targ...

Prostate cancer is the leading form of cancer in men. Prostate tumors often contain neuroendocrine differentiation, which correlates with androgen-independent progression and poor prognosis. Matrix metalloproteinases (MMP), a family of enzymes that remodel the microenvironment, are associated with tumorigenesis and metastasis. To evaluate MMPs during metastatic prostatic neuroendocrine cancer d...

BACKGROUND An essential step in the process of tumor invasion and metastasis involves the degradation of tissue barriers in the extracellular matrix (ECM), particularly in the basal membrane (BM). Matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs), in particular MMP-2, MMP-7, TIMP-1 and TIMP-2, play an important role in the process of ECM and BM degradat...

BACKGROUND Matrix metalloproteinases (MMPs) have been implicated in the invasion and metastasis of head and neck squamous cell carcinoma (HNSCC). However, a detailed analysis of MMPs and tissue inhibitors of MMPs (TIMPs) in relation to the biological behavior of HNSCC has yet to be performed in clinical material. OBJECTIVES To study a comprehensive profile of MMPs and their 2 main inhibitors ...

Objective We aimed to investigate the relationship of expression of matrix metalloproteinase-7 (MMP-7), tissue inhibitor of metalloproteinase-1 (TIMP-1) and cyclooxygenase-2 (COX-2) in colon cancer and its predecessor colon polyp. Materials and methods This study included 29 patients with colon polyp, 19 patients with colon cancer and 65 healthy control subjects. The expressions of MMP-7, TIM...

The syndecan family of heparan sulfate proteoglycans contributes to cell adhesion and communication by serving as co-receptors for cell signaling and extracellular matrix molecules. Syndecan-2 is located at the cell surface, and we previously reported that it induces matrix metalloproteinase-7 (MMP-7) expression in colon cancer cells. However, the underlying regulatory mechanisms are unknown. H...

Epithelial cell responses to bacterial infection include induction of matrix metalloproteinase 7 (MMP-7). Here, we identify increased MMP-7 expression in the gastric epithelium in response to the oncogenic bacterium Helicobacter pylori, and report on the mechanisms and consequences for gastric epithelial cell migration. In patients infected with H. pylori, there was increased MMP-7 in gastric b...

Motivation/Background:The metastasis of tumor cells consists steps such as epithelial-mesenchymal transition, transendothelial migration and the formation metastatic colonization. E-Cadherin vimentin are main proteins associated with EMT, whereas MMP-9 is migration.
 Method:We aimed to investigate effects boric acid resveratrol comparatively on metaatatic behaviors MCF-7. 30μM 50μM were ad...

the variants of angiotensin converting enzyme (ace) and matrix metalloproteinases (mmps) genes might be involved in the pathogenesis of end stage renal disease (esrd) and hypertension. we studied the ace insertion/deletion (i/d) and mmp-7 a-181g variants in 99 unrelated esrd patients and 117 individuals without renal complications from western iran with kurdish ethnic background. the frequency ...
