This study investigated the effects of acute serotonin depletion on two measures of impulsive behavior in healthy men with a family history of alcoholism. Serotonin has been implicated in several forms of impulsive behavior, as well as in the etiology of Type II alcoholism. The present study was designed to determine if an acute disturbance of serotonin(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)
MiRNAs can have pleiotropic effects by targeting multiple genes belonging to diverse signalling networks. Alternatively, miRNAs can enhance the potency of their cellular effects by targeting multiple genes within the same genetic pathway. Previously, we and others have demonstrated that miR-335 is a potent suppressor of tumour cell migration, invasion and(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)
Notwithstanding controversies over the role of epithelial to mesenchymal transition in the pathogenesis of renal disease, the last decade has witnessed a revolution in our understanding of the regulation of renal cell plasticity. Significant parallels undoubtedly exist between ontogenic processes and the initiation and propagation of damage in the diseased(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)
INTRODUCTION When I took Econ 100 and Econ 5100, no one talked about fear, or greed, or hubris, or irrational exuberance. The closest were a few closet Keynesians who reminded us of " animal spirits. " For now, the focus has rightly been on crisis management. In this paper, I look more at medium-term policy responses. My thesis is that policy-makers and(More)
