Claudin-4 expression is associated with tumor invasion, MMP-2 and MMP-9 expression in gastric cancer

The relationship between MMP-2 and MMP-9 expression levels with breast cancer incidence and prognosis

The relationship between the expression levels of matrix metalloproteinase-2 (MMP-2) and MMP-9 and breast cancer prognosis was studied. Two breast cancer cell lines (MDA-MB-231 and MCF-7) and one human normal breast cell line (HS578Bst) were investigated. Fluorescence real-time reverse transcription-polymerase chain reaction (RT-PCR) and western blotting were used to detect cellular mRNA and pr...

Claudin-4 expression in gastric cancer cells enhances the invasion and is associated with the increased level of matrix metalloproteinase-2 and -9 expression

Claudin-4 is a member of a large family of transmembrane proteins known as claudins, which are essential for the formation and maintenance of tight junctions. Our previous studies have revealed that claudin-4 proteins are overexpressed in metastatic gastric cancer. To clarify the roles of claudin-4 in gastric cancer metastasis, human gastric adenocarcinoma (AGS) cells constitutively expressing ...

Profiles of MMP-2 Expression in Jurkat, Molt-4 and U937 Cells

Background: Leukemia is a malignant proliferative disorder of the hematopoietic cells. The important role of angiogenesis in leukemia has been reported by several studies. Matrix metalloproteinases (MMPs) are a large group of endopeptidases which degredate the extracellular matrix and play an important role in angiogenesis. Objective: The present study was conducted to evaluate the patterns of ...

Investigation of MMP-2 and MMP-9 activities in canine sera with dilated cardiomyopathy

Dilated cardiomyopathy (DCM) is accompanied by myocytes and connective tissue changes. Matrix metalloproteinases (MMPs) play important roles in cardiac remodeling. It seems that the gelatinases (MMP-2 and MMP-9) are effective enzymes in cardiomyopathy. Dilated cardiomyopathy was confirmed in 22 dogs (patient group) including 11 female and 11 male by clinical examination, auscultation, thoracic ...

MMP-2, MMP-9 and MMP-12 expression in flexor tenosynovium in idiopathic carpal tunnel syndrome
