Prostate cancer is characterized by the recurrent translocation of ETS transcription factors, including ETS variant 1 (ETV1) [also known as ETS-related 81 (ER81)]. Transgenic ETV1 mice develop prostatic intraepithelial neoplasia, yet the mechanisms by which ETV1 exerts its deleterious function remain largely unexplored. In this study, we demonstra...

Multiple sclerosis (MS) is a progressive autoimmune disease of the central nervous system (CNS) in which demyelination, axonal inflammation and damage occurs. The aim of present study was to investigate the influence of matrix metalloproteinase (MMP)-3 5A/6A and its interaction with MMP-7 A-181G polymorphism on the risk and the clinical course of MS. We studied 121 patients and 106 healthy indi...

The capacity of inflammatory cell-derived matrix metalloproteinases (MMPs) to cleave tissue factor pathway inhibitor (TFPI) and alter its activity was investigated. MMP-7 (matrilysin) rapidly cleaved TFPI to a major 35-kDa product. In contrast, MMP-1 (collagenase-1), MMP-9 (gelatinase B), and MMP-12 (macrophage elastase) cleaved TFPI into several fragments including the 35-kDa band. However, ra...

PURPOSE A prerequisite for the development of vaccination strategies is the identification and characterization of relevant tumor-associated antigen. Using microarray and reverse transcription-PCR analysis, we found matrix metalloproteinase (MMP)-7 to be extensively up-regulated in renal cell carcinomas and expressed in a broad variety of malignant cells. MMP-7 can promote cancer invasion and a...

OBJECTIVE There is increasing evidence to indicate that MMP-7 plays a more important role in tumor progression than other MMPs. The aim of this study was to detect MMP-7 expression in human rectal cancer and normal rectal tissue and to determine whether it is correlated with invasion and metastasis of human rectal cancer. METHODS Eighty-six paired samples of rectal cancer and distant normal r...

The study objective was to determine the presence of MMP-7 in cancer tissue in correlation with its serum level in patients diagnosed with colorectal cancer (CRC). In 45 patients with CRC, MMP-7 expression was assessed immunohistochemically on FFPE slides in tumours (N = 37) and in the corresponding surgical margin sample. MMP-7 serum level was measured preoperatively. The expression of MMP-7 i...

To investigate simultaneously localization and relative activity of MMPs during extracellular matrix (ECM) remodeling in bleomycin-induced pulmonary fibrosis in rat, we analyzed the time course of the expression, activity and/or concentration of gelatinases MMP-2 and MMP-9, collagenase MMP-1, matrylisin MMP-7, TIMP-1 and TIMP-2, both in alveolar space (cellular and extracellular compartments) a...

Aim: Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease with short overall survival. It is of great significance to identify new biomarkers to predict prognosis of PDAC patients after surgery. Methods: In this study, we examined the expression of CD147 and MMP-7 in 90 PDAC neoplastic tissues and paired non-neoplastic tissues from patients who underwent surgery and followed-up for as lo...

BACKGROUND Matrix metalloproteinase 2 (MMP-2) has been reported to be an important regulator of cell migration and invasion through degradation of the extracellular matrix (ECM) in many diseases, such as cancer and endometriosis. Here, we found calcium-activated neutral protease 7 (CAPN 7) expression was markedly upregulated in the eutopic endometrium and endometrial stromal cells of women diag...

The molecular mechanisms underlying progressive liver fibrosis following surgical treatment of biliary atresia (BA) remain unclear. Our aim was to address hepatic gene and protein expression and serum levels of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) after successful portoenterostomy (PE), and relate them to histological signs of liver injury, clinical follow-up dat...
