A mutation in the CLN8 gene in English Setter dogs with neuronal ceroid-lipofuscinosis.

A heritable neurodegenerative disease of English Setters has long been studied as a model of human neuronal ceroid-lipofuscinosis (NCL). Megablast searches of the first build of the canine genome for potential causative genes located the CLN8 gene near the q telomere of canine chromosome 37, close to a marker previously linked to English Setter NCL. Sequence analysis of the coding region from affected dogs revealed a T-to-C transition in the CLN8 gene that predicts a p.

Assessment of dietary therapies in a canine model of Batten disease.

The neuronal ceroid lipofuscinoses (NCLs) are inherited neurodegenerative diseases that occur in a number of animal species, including dogs. A study was conducted to determine whether the resupply of nutrients lost in NCL English Setter dogs would modify the course of the disease. Carnitine and polyunsaturated fatty acids have been reported to be reduced in NCL English Setters.

Studies of renal injury III: lipid-induced nephropathy in type II diabetes.

Unlabelled: Studies of renal injury III: Lipid-induced nephropathy in type II diabetes.

Background: Nephrotoxicity from elevated circulating lipids occurs in experimental and clinical situations. We tested the hypothesis that lipid-induced nephropathy causes advanced renal failure in rats with type II diabetes and dyslipidemia.

Mutational analysis of the defective protease in classic late-infantile neuronal ceroid lipofuscinosis, a neurodegenerative lysosomal storage disorder.

The late-infantile form of neuronal ceroid lipofuscinosis (LINCL) is a progressive and ultimately fatal neurodegenerative disease of childhood. The defective gene in this hereditary disorder, CLN2, encodes a recently identified lysosomal pepstatin-insensitive acid protease. To better understand the molecular pathology of LINCL, we conducted a genetic survey of CLN2 in 74 LINCL families.

Altered mitochondrial function in canine ceroid-lipofuscinosis.

The neuronal ceroid-lipofuscinoses (NCL) are a group of autosomal recessively inherited neurodegenerative disorders characterized by progressive dementia, neuronal atrophy, and premature death. The late infantile and juvenile types of NCL show massive accumulation of mitochondrial ATP synthase subunit c protein in both mitochondria and lysosomes. The specific accumulation of this mitochondrial protein suggests that mitochondrial function may be impaired in the NCL diseases.
