retinal degeneration/obesity

Metabolic syndrome (MetS) is associated with several degenerative diseases, including retinal degeneration. Previously, we reported on progressive retinal degeneration in a spontaneous obese rat (WNIN/Ob) model. In this study, we investigated the additional effect of impaired glucose tolerance

OBJECTIVE A strong association between retinal degeneration and obesity has been shown in humans. However, the molecular basis of increased risk for retinal degeneration in obesity is unknown. Thus, an animal model with obesity and retinal degeneration would greatly aid the understanding of

OBJECTIVE Obesity is associated with various health afflictions, including ocular complications such as diabetic retinopathy, high intraocular pressure, cataracts, and macular degeneration. We previously reported progressive retinal degeneration after the onset of obesity in the spontaneously obese

The tub gene is a member of a small, well conserved neuronal gene family of unknown function. Mutations within this gene lead to early-onset blindness and deafness, as well as late-onset obesity and insulin resistance. To test the hypothesis that mutations within other members of this gene family

OBJECTIVE To evaluate and compare the protective effect of tauroursodeoxycholic acid (TUDCA) on photoreceptor degeneration in different models of retinal degeneration (RD) in mice. METHODS Bbs(M390R/M390R) mice were injected subcutaneously twice a week, from P40 to P120, and rd10 mice were injected

Retinopathy, a common complication of diabetes, is characterized by an unbalanced production of nitric oxide (NO), a process regulated by nitric oxide synthase (NOS). We hypothesized that retinopathy might stem from changes in the insulin receptor substrate (IRS)/PI3K/AKT pathway and/or expression

Alström Syndrome is a ciliopathy associated with obesity, insulin resistance/type 2 diabetes mellitus, cardiomyopathy, retinal degeneration, hearing loss, progressive liver and kidney disease, and normal cognitive function. ALMS1, the protein defective in this disorder, localizes to the

BACKGROUND Although individual occurrence is rare, syndromic obesity with mental retardation has been reported in conjunction with 140 different diseases. METHODS The patient was born at term after a pregnancy complicated by threatened miscarriage. A diagnosis of Bardet-Biedl syndrome (BBS; OMIM

Obesity associates with increased health risks such as heart disease, stroke and diabetes. The steady rise in the obese population worldwide poses an increasing burden on health systems. Genetic factors contribute to the development of obesity, and the elucidation of their physiological functions

Mice that carry the recessive mutation tub develop neurosensory defects including retinal and cochlear degeneration, as well as maturity-onset obesity associated with insulin resistance. The biological function of the gene and the mechanism by which it induces its phenotypes are still unclear. In

Alstrom syndrome is a rare autosomal recessive disorder characterized by retinal degeneration, sensorineural hearing loss, obesity, type 2 diabetes mellitus and chronic nephropathy. It may be associated with acanthosis nigricans, hypergonadotropic hypogonadism, hepatic dysfunction, hepatic

Mice homozygous for a defect of the tub (rd5) gene exhibit cochlear and retinal degeneration combined with obesity, and resemble certain human autosomal recessive sensory deficit syndromes. To establish the progressive nature of sensory cell loss associated with the tub gene, and to differentiate

BACKGROUND The tubby (tub) and tubby-like protein (tulp) genes encode a small family of proteins found in many organisms. Previous studies have shown that TUB and TULP genes in mammalian involve in obesity, neural development, and retinal degeneration. The purpose of this study was to investigate
