PURPOSE Age-related macular degeneration (ARMD) is characterized by progressive thickening and accumulation of various lipid-rich extracellular matrix (ECM) deposits under the retinal pigment epithelium (RPE). ECM dysregulation probably contributes to the pathologic course of ARMD. By activating estrogen receptors (ERs), estrogens regulate the expression of(More)
Diabetic glomerulosclerosis is characterized by the accumulation of extracellular matrix (ECM) in the mesangium. Estrogens seem to retard whereas estrogen deficiency seems to accelerate progressive glomerulosclerosis. Thus, mesangial cells (MC) may be a target for estrogens. Estrogen action is mediated via estrogen receptor (ER) subtypes ERalpha and ERbeta.(More)
PURPOSE Estrogen status influences the incidence and severity of many diseases in women. Because women with early menopause appear at risk for worse ARMD, estrogen deficiency may also contribute to the onset or severity of ARMD in women. It has been observed that aged male C57BL/6 mice fed a high-fat diet and briefly exposed to blue-green light exhibit(More)
We previously reported that one of the main components of the sclerotic material in human glomerular diseases was type IV collagen. In this study we examined the contribution of increased synthesis to this process at the gene expression level. Sufficient material has not been available to study type IV collagen synthesis by normal or sclerotic glomeruli in(More)
Mice transgenic for growth hormone (GH) develop progressive glomerulosclerosis. The compositions of kidney extracellular matrix (ECM) and ECM mRNA were examined. The glomerulosclerotic areas in GH mice contained types I and IV collagen, laminin, and basement membrane heparan sulfate proteoglycan (HSPG), which increased with age. The type IV collagen,(More)
BACKGROUND Angiotensin converting enzyme inhibitor (ACEi) therapy delays the onset of renal failure in diabetic nephropathy and inhibits or delays the onset of proteinuria in several animal models. MATERIALS AND METHODS We examined this question using a transgenic model of chronic glomerulosclerosis caused by an excess production of growth hormone (GH) in(More)
Five/six nephrectomy induces systemic and glomerular hypertension, glomerulosclerosis, proteinuria, and tubulointerstitial fibrosis. Polysulfate pentosan (PPS) decreases mesangial proliferation and extracellular matrix accumulation. The aim of this study was to determine whether PPS prevents glomerular hemodynamic changes and renal damage. Micropuncture(More)
The isolation and characterization of human (1-7), and animal (see reference 8 for a review) glomerular cells has been reported. However, it has been difficult to obtain endothelial cells from the glomeruli in any species. Endothelial cells have been isolated from large blood vessels of many species, and recently, from small blood vessels of several(More)
The genetic background plays an important role in the development of progressive glomerulosclerosis. However, no marker is available for the reliable prediction of genetic susceptibility to glomerulosclerosis. Because matrix metalloproteinase-9 (MMP-9) levels are decreased in models of glomerulosclerosis and MMP-9 promoter polymorphism has been observed(More)
