BACKGROUND Recurrence of disease after surgically induced remission constitutes a major and largely unpredictable problem in Crohn's disease (CD). Matrix metalloproteinases (MMP) and the tissue inhibitors of metalloproteinases (TIMP) are involved in the (etio)pathogenesis of CD and may thereby also affect postsurgical outcome. We studied the predictive value of 1) allelic composition at MMP, TI...

Our objective was to determine the presence of vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP-2) and MMP-9 and specific tissue inhibitors of matrix metalloproteinase (TIMP-1 and TIMP-2) in tumor samples obtained from patients with primary breast cancer. We attempted to correlate these findings with the status of the sentinel lymph node (SLN) and clinical-pathological...

Secreted metalloproteinases (MPs) and their specific inhibitors (TIMPs, tissue inhibitors of MPs) are important mediators of extracellular matrix metabolism. Previous studies have linked either excessive MP release or reduced TIMP-1 production to the invasive and metastatic phenotypes of cancer cells. In the present study we investigated the relationship between the expression of TIMP-1 and the...

BACKGROUND AND OBJECTIVE Matrix metalloproteinases (MMP) and their inhibitors, tissue inhibitors of metalloproteinases (TIMP), regulate homeostasis and turnover of the extra cellular matrix. The aim of this study was to investigate the associations of serum MMP-9 and TIMP-1 with lung function. METHODS Spirometry was performed in a population-based sample of 888 subjects aged 70 years. Serum M...

The matrix metalloproteinases (MMPs) have been associated with tumor cell invasion and metastasis of human cancers by mediating the degradation of extracellular matrix components. Therefore, these enzymes and their inhibitor (TIMP-2) constitute promising targets in the development of anticancer therapies. In order to investigate the correlation between expressions of TIMP-2, MMPs and clinical o...

Lewis (y) antigen is a difucosylated oligosaccharide present on the plasma membrane, and its overexpression is frequently found in human cancers and has been shown to be associated with poor prognosis. Our previous studies have shown that Lewis (y) antigen plays a positive role in the process of invasion and metastasis of ovarian cancer cells. However, the mechanisms by which Lewis (y) antigen ...

Tissue inhibitors of metalloproteinases (TIMPs) are a family of multifunctional proteins known to possess a broad range of biological activities, including inhibition of metalloproteinase activity, regulation of proliferation and apoptosis of a variety of cell types, and, depending on the context, differential regulation of angiogenic and inflammatory responses. Elevated mRNA expression of TIMP...

Local disruption of the integrity of both the myoepithelial cell layer and the basement membrane is an indispensable prerequisite for the initiation of invasion and the conversion of human breast ductal carcinoma in situ (DCIS) to infiltrating ductal carcinoma (IDC). We previously reported that human endometase/matrilysin-2/matrix metalloproteinase (MMP) 26-mediated pro-gelatinase B (MMP-9) act...

AIMS Tissue inhibitor of metalloproteinases-1 (TIMP-1) is a key regulator of extracellular matrix degradation. We examined relations of plasma total TIMP-1 to cardiovascular risk factors and echocardiographic left ventricular (LV) structure and function in a community-based sample. METHODS AND RESULTS We studied 1069 Framingham Heart Study participants (mean age 56 years, 58% women) free of h...

Matrix metalloproteinases (MMPs) function in the remodeling of the extracellular matrix that is integral for many normal and pathological processes. The tissue inhibitor of metalloproteinases family, including tissue inhibitor of metalloproteinases-2 (TIMP-2), regulates the activity of these multifunctional metalloproteinases. TIMP family members are proteinase inhibitors that contain six conse...
