N-acetyl-L-glutamate in brain: assay, levels, and regional and subcellular distribution.

1991

N-Acetyl-L-glutamate (NAG), the activator of mitochondrial carbamoyl phosphate synthetase (CPS), is demonstrated by several methods, including a new HPLC assay, in the brain of mammals and of chicken. The brain levels of NAG are 200-300 times lower than the levels of N-acetyl-L-aspartate (NAA), and are similar to the levels of NAG in rat liver. The NAG levels in chicken liver are very low. Although NAG is mitochondrial in the liver, it is cytosolic in brain. Using enzyme activity and immuno assays we did not detect CPS in brain (detection limit, 12.5 micrograms/g brain), excluding that brain NAG is involved in citrullinogenesis. The regional distribution of brain NAG differs from that of NA…

Central nervous system involvement at first relapse in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycl…

2009

Background The prevalence of and risk factors for central nervous system recurrence in patients with acute promyelocytic leukemia are not well established and remain a controversial matter. Design and Methods Between 1996 and 2005, 739 patients with newly diagnosed acute promyelocytic leukemia enrolled in two consecutive trials (PETHEMA LPA96 and LPA99) received induction therapy-with all-trans retinoic acid and idarubicin. Consolidation therapy comprised three courses of anthracycline monochemotherapy (LPA96), with all-trans retinoic acid and reinforced doses of idarubicin in patients with an intermediate or high risk of relapse (LPA99). Central nervous system prophylaxis was not given. Re…

Affinity Cleavage of Carbamoyl-Phosphate Synthetase I Localizes Regions of the Enzyme Interacting with the Molecule of ATP that Phosphorylates Carbam…

1995

Two ATP molecules are used in the reaction catalyzed by carbamoyl-phosphate synthetase I. One molecule (ATPA) phosphorylates HCO3- and the other (ATPB) phosphorylates carbamate. Carbamoyl-phosphate synthetase I is a 160-kDa polypeptide consisting of a 40-kDa N-terminal moiety and a 120-kDa C-terminal moiety, the latter being composed of two similar halves of molecular mass 60 kDa. We showed [Alonso, E., Cervera, J., Garcia-Espana, A., Bendala, E. & Rubio, V. (1992) J. Biol. Chem. 267, 4524-4532] that Fe.ATP bound at the site for ATPB catalyzes the oxidative inactivation of carbamoyl-phosphate synthetase I in a model oxidative system consisting of Fe3+, ascorbate, and O2, and we detected ATP…
