Hyperammonemia: regulation of argininosuccinate synthetase and argininosuccinate lyase genes in aggregating cell cultures of fetal rat brain.
Hyperammonemia in the brain leads to poorly understood alterations of nitric oxide (NO) synthesis. Arginine, the substrate of nitric oxide synthases, might be recycled from the citrulline produced with NO by argininosuccinate synthetase (AS) and argininosuccinate lyase (AL). The regulation of AS and AL genes during hyperammonemia is unknown in the brain. We used brain cell aggregates cultured f...
متن کاملincreased expression of glial cell line-derived neurotrophic factor in rat brain after traumatic brain injury
glial cell line-derived neurotrophic factor (gdnf) plays important roles not only for the differentiation of neurons during normal development but also for the survival and recovery of many populations of mature neurons. the effect of traumatic brain injury (tbi) on the expression of gdnf is currently unknown. to determine if there is alteration in gdnf after tbi we examined the effect of contr...
متن کاملComparison of argininosuccinate synthetase from young and old rat livers.
Properties of argininosuccinate synthetases (ASS), including immunological properties and heat stability, from young and old rats were quite similar. However the degradation rates of ASS from young and old rats were found to be different as shown in the experiment using the double labeling technique. Three forms of this enzyme from young and old rat livers were separated by DEAE-Sephadex A-50 c...
متن کاملNitro analogs of substrates for argininosuccinate synthetase and argininosuccinate lyase.
The nitro analogs of aspartate and argininosuccinate were synthesized and tested as substrates and inhibitors of argininosuccinate synthetase and argininosuccinate lyase, respectively. The Vmax for 3-nitro-2-aminopropionic acid was found to be 60% of the maximal rate of aspartate utilization in the reaction catalyzed by argininosuccinate synthetase. Only the nitronate form of this substrate, in...
متن کاملRegulation of glucocorticoids of arginase and argininosuccinate synthetase in cultured rat hepatoma cells.
We have examined and characterized the regulation by glucocorticoids of the levels of arginase and argininosuccinate synthetase in two rat hepatoma cell lines (H4-II-E-C3 and MH1C1). Hydrocortisone elevates the activity of both enzymes in a time- and dose-dependent fashion. This effect was blunted markedly by small amounts of ethanol (0.1 to 0.9% [v/v]) and blocked substantially by a high molar...
