N-Acetylaspartate Metabolism Outside the Brain: Lipogenesis, Histone Acetylation, and Cancer
N-acetylaspartate (NAA) is a highly abundant brain metabolite. Aberrant NAA concentrations have been detected in many pathological conditions and although the function of NAA has been extensively investigated in the brain it is still controversial. Only recently, a role of NAA has been reported outside the brain. In brown adipocytes, which show high expression of the NAA-producing and the NAA-c...
متن کاملN-acetylaspartate catabolism determines cytosolic acetyl-CoA levels and histone acetylation in brown adipocytes
Histone acetylation depends on the abundance of nucleo-cytoplasmic acetyl-CoA. Here, we present a novel route for cytoplasmic acetyl-CoA production in brown adipocytes. N-acetylaspartate (NAA) is a highly abundant brain metabolite catabolized by aspartoacylase yielding aspartate and acetate. The latter can be further used for acetyl-CoA production. Prior to this work, the presence of NAA has no...
متن کاملN-Acetylaspartate reductions in brain injury: impact on post-injury neuroenergetics, lipid synthesis, and protein acetylation
N-Acetylaspartate (NAA) is employed as a non-invasive marker for neuronal health using proton magnetic resonance spectroscopy (MRS). This utility is afforded by the fact that NAA is one of the most concentrated brain metabolites and that it produces the largest peak in MRS scans of the healthy human brain. NAA levels in the brain are reduced proportionately to the degree of tissue damage after ...
متن کاملAcetylation and Histone Deacetylase Inhibitors in Cancer
In recent years, the role of epigenetics in the development and treatment of cancer has gained interest and the effects of internal and external factors on the epigenetic profile are under investigation. The term “epigenetics” refers to modifications that influence phenotype without altering genotype. Epigenetic changes are potentially reversible but generally stably maintained during the cell ...
متن کاملN-acetylaspartate in brain – studies on efflux and function
N-acetylaspartate (NAA) is an amino acid derivative present in high concentration in the brain. The function of NAA is still unsettled in spite of 50 years of research. The mainly neuronal synthesis and glial breakdown of NAA requires a well regulated neuronal efflux and glial uptake. In the present work hippocampal slices were used to study how NAA efflux from neurons is regulated and to furth...
