Novel prognostic markers for progression of kidney disease are needed to distinguish patients who might benefit from a more aggressive nephroprotective therapy. Expression of the proteoglycan versican was evaluated in renal transcriptomics profiles and in an independent set of 74 renal biopsies. Versican levels were correlated to histologic damage scores and to renal outcome, and versican expre...
Chondroitin sulfate proteoglycan (CS-PG) expression is increased in response to CNS injury and limits the capacity for axonal regeneration. Previously we have shown that neurocan is one of the CS-PGs that is upregulated (Asher et al., 2000). Here we show that another member of the aggrecan family, versican, is also upregulated in response to CNS injury. Labeling of frozen sections 7 d after a u...
We have cloned an alternatively spliced glycosaminoglycan attachment domain (GAG-alpha) of human versican from cDNA libraries derived from U251MG glioma cells. Inserted carboxyl-terminal of the hyaluronan-binding region, this domain adds another 987 amino acids to the original versican (V1) core protein giving rise to the large V0 isoform with 3396 amino acids and 17-23 putative glycosaminoglyc...
MicroRNA (miR)-203 has been demonstrated to function as a suppressor in tumorigenesis. Recently, miR-203 was reported to play a role in malignant melanoma (MM); however, the detailed function of miR-203 in MM remains unclear. In the present study, the expression of miR-203 was shown to be significantly downregulated in MM tissues when compared with normal adjacent tissues. Based on a bioinforma...
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...
BACKGROUND Versican, a chondroitin sulphate proteoglycan, is one of the key components of the provisional extracellular matrix expressed after injury. The current study evaluated the hypothesis that a versican-rich matrix alters the phenotype of cultured fibroblasts. METHODS AND RESULTS The full-length cDNA for the V1 isoform of human versican was cloned and the recombinant proteoglycan was e...
AIMS To determine versican-producing cells in normocellular bone marrow and to evaluate chronological alteration in the number of versican-producing macrophages in bone marrow of patients with acute myelogenous leukaemia (AML) after cord blood stem cell transplantation (CBSCT) to gain insight in the significance of versican in recovery of haematopoiesis. METHODS We enrolled seven age-matched ...
During ovulation, production of a specialized hyaluronan (HA)-rich matrix cross-linked by associated HA binding factors causes expansion of the cumulus oocyte complex. Versican is a member of the hyalectan family that binds HA, provides structure and elasticity to tissues, and impacts cell motility and adhesion. In these studies, we sought to determine whether versican is synthesized by ovulati...
Extracellular matrix (ECM) 1 expansion contributes to airway remodeling in asthma. This study examines the effect of leukotriene D4 (LTD4), combined with EGF, on proteoglycan synthesis by cultured human bronchial smooth muscle cells (BSMCs). LTD4 plus EGF stimulated proliferation of BSMCs with increased versican synthesis. Further, versican mRNA splice variants, V0 and V1, were differently regu...
The systematic application of antiangiogenic therapy remains an issue of concern, mainly due to the hypoxic and inflammatory changes in the tumor microenvironment elicited by antiangiogenic therapy. Versican, a 'bridge' connecting inflammation with tumor progression as well as playing a central role in the generation of an inflammatory tumor microenvironment is a promising candidate for the int...
