Connective tissue growth factor [CTGF]/CCN2 is a prototypic member of the CCN family of regulatory proteins. CTGF expression is up-regulated in a number of fibrotic diseases, including diabetic nephropathy, where it is believed to act as a downstream mediator of TGF-beta function; however, the exact mechanisms whereby CTGF mediates its effects remain(More)
PURPOSE Pseudoexfoliation (PXF) syndrome is a generalized disorder of the extracellular matrix (ECM) involving the trabecular meshwork (TM), associated with raised intraocular pressure, glaucoma, and cataract. The purposes of this study were to quantify aqueous humor connective tissue growth factor (CTGF) in PXF glaucoma, to determine the effect of CTGF on(More)
BACKGROUND Renal interstitial fibrosis and glomerular sclerosis are hallmarks of diabetic nephropathy (DN) and several studies have implicated members of the WNT pathways in these pathological processes. This study comprehensively examined common genetic variation within the WNT pathway for association with DN. METHODS Genes within the WNT pathways were(More)
Connective tissue growth factor (CTGF/ CCN2) is a 38-kDa secreted protein, a prototypic member of the CCN family, which is up-regulated in many diseases, including atherosclerosis, pulmonary fibrosis, and diabetic nephropathy. We previously showed that CTGF can cause actin disassembly with concurrent down-regulation of the small GTPase Rho A and proposed an(More)
PURPOSE We have previously demonstrated elevated levels of connective tissue growth factor (CTGF/CCN2) in the aqueous humor (AqH) of pseudoexfoliation glaucoma (PXFG) patients when compared with cataract controls. Furthermore, there is a significant trabecular meshwork (TM) and lamina cribrosa (LC) fibrotic phenotype associated with glaucoma, possibly(More)
AIMS/HYPOTHESIS Several studies have provided compelling evidence implicating the Wnt signalling pathway in the pathogenesis of diabetic nephropathy. Gene expression profiles associated with renal fibrosis have been attenuated through Wnt pathway modulation in model systems implicating Wnt pathway members as potential therapeutic targets for the treatment(More)
CCN2/CTGF is an established effector of TGFβ driven responses in diabetic nephropathy. We have identified an interaction between CCN2 and TGFβ leading to altered phenotypic differentiation and inhibited cellular migration. Here we determine the gene expression profile associated with this phenotype and define a transcriptional basis for differential actin(More)
