Neuronal and glial coexpression of argininosuccinate synthetase and inducible nitric oxide synthase in Alzheimer disease.
The enzyme argininosuccinate synthetase (ASS) is the rate limiting enzyme in the metabolic pathway leading from L-citrulline to L-arginine, the physiological substrate of all isoforms of nitric oxide synthases (NOS). ASS and inducible NOS (iNOS) expression in neurons and glia was investigated by immunohistochemistry in brains of Alzheimer disease (AD) patients and nondemented, age-matched contr...
متن کاملDistribution and co-localization of nitric oxide synthase and argininosuccinate synthetase in the cat hypothalamus.
Argininosuccinate synthetase (ASS) and nitric oxide synthase (NOS) comprise part of the cyclic metabolic pathway to produce nitric oxide (NO). ASS is one of the arginine synthesis enzymes which synthesizes argininosuccinate from aspartate and citrulline, and NOS forms NO and citrulline from arginine. This study examines the localization of ASS and NOS in the cat hypothalamus using nicotinamide ...
متن کاملComparison of inducible nitric oxide synthase activity in pancreatic islets of young and aged rats
Objective(s):Some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. Incidence of these condition increases with aging. On the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (NOS) activity is also altered in diabetes. In this study, modification in the enzyme activity associated with aging a...
متن کاملNeuronal expression of inducible nitric oxide synthase in hypothyroid rat.
OBJECTIVES The expression of iNOS mRNA and protein levels was studied in hypothyroid rat cerebral cortex during early days after postnatal life. METHOD The homogenate of the cerebral cortex was examined using Real-time reverse transcription polymerase chain reaction (real-time RT PCR) and Western blot analysis. RESULT ΔCt in hypothyroid group on day 7, 14, 21 was 18.89±0.92, 18.83±0.99, 16....
متن کاملAloe vera toxic effects: expression of inducible nitric oxide synthase (iNOS) in testis of Wistar rat
Objective(s): Nitric oxide (NO), a product of inducible nitric oxide synthase (iNOS), contributes in germ cell apoptosis. This study was aimed to evaluate the effects of Aloe vera gel (AVG) on male Wistar rat reproductive organ, serum NO level, and expression of iNOS gene in leydig cells. Materials and Methods:Adult male Wistar rats (n=36) were used for experiments in three groups. The experim...
