one of the main members of the large aggregating proteoglycans (pgs) family is versican which is able to bind to hyaluronate. versican is a chondroitin sulfate proteoglycan and is a key ingredient of the extracellular matrix.  due to its widespread expression in the body, versican is involved in cell adhesion, proliferation and migration. induced expression of versican is often observed in tiss...

The expression of the large chondroitin sulfate proteoglycan versican was studied in human adult skin. For this purpose, bacterial fusion proteins containing unique portions of the versican core protein were prepared. Polyclonal antibodies against the fusion proteins specifically reacted with versican from a proteoglycan fraction of MG63 osteosarcoma cells. In immunohistochemical experiments, t...

AIMS To study the expression of versican, a large proteoglycan involved in repressing adhesion between cells and the extracellular matrix in pharyngeal squamous cell carcinoma (PSCC), and its relation to the expression of p53 and catenins, histological differentiation, clinical data, and prognosis. METHODS For the retrospective survey, primary tumours for analyses were obtained from 118 patie...

Leiomyosarcoma (LMS) is a mesenchymal cancer that occurs throughout the body. Although LMS is easily recognized histopathologically, the cause of the disease remains unknown. Versican, an extracellular matrix proteoglycan, increases in LMS. Microarray analyses of 80 LMSs and 24 leiomyomas showed a significant elevated expression of versican in human LMS versus benign leiomyomas. To explore the ...

Versican is a large extracellular chondroitin sulfate proteoglycan that belongs to the family of lecticans. Alternative splicing of versican generates at least four isoforms named V0, V1, V2, and V3. We show here that ectopic expression of versican V1 isoform induced mesenchymal–epithelial transition (MET) in NIH3T3 fibroblasts, and inhibition of endogenous versican expression abolished the MET...

We previously reported that versican, a large chondroitin sulfate proteoglycan, isolated from a renal adenocarcinoma cell line, ACHN, binds L-selectin. Here we report that versican also binds certain chemokines and regulates chemokine function. This binding was strongly inhibited by the chondroitinase digestion of versican or by the addition of soluble chondroitin sulfate (CS) B, CS E, or hepar...

Distal outgrowth and maturation of mesenchymalized endocardial cushions are critical morphogenetic events during post-EMT atrioventricular (AV) valvuloseptal morphogenesis. We explored the role of BMP-2 in the regulation of valvulogenic extracellular matrix (ECM) components, versican and hyaluronan (HA), and cell migration during post-EMT AV cushion distal outgrowth/expansion. We observed inten...

Background & Objective: Gastric cancer is the second most frequent cause of cancer death worldwide, despite differences in incidence around the world. The majority of gastric cancer cases concern gastric adenocarcinoma, which has a fairly high 5-year survival rate when coupled with early-stage diagnosis. Versican, a member of the aggregating chondroitin sulfate proteoglycans fa...

BACKGROUND Versican expression may enhance tumor invasion and metastasis. However, the expression of versican in human endometrial cancer has seldom been characterized. The aim of this study was to investigate versican expression in endometrial cancers. PATIENTS AND METHODS We immunohistochemically investigated the expression of versican protein in 167 endometrial cancers and analyzed the cor...

We show that combinatorial mouse alleles for the secreted metalloproteases Adamts5, Adamts20 (bt), and Adamts9 result in fully penetrant soft-tissue syndactyly. Interdigital webs in Adamts5(-/-);bt/bt mice had reduced apoptosis and decreased cleavage of the proteoglycan versican; however, the BMP-FGF axis, which regulates interdigital apoptosis was unaffected. BMP4 induced apoptosis, but withou...
