چکیده

Background: Imbalances in cellular energy homeostasis can lead to diseases such as type 2 diabetes, cardiovascular disease and cancer. The heart, which has to contract incessantly, is very sensitive to nutritional changes and requires optimal energy to fuel adjustment [1]. N-acetylaspartate (NAA) is one of the most abundant metabolites in brain [2] with yet unknown function. NAA is synthesized by mitochondrial N-acetyltransferase 8-like (NAT8L) and catabolized by cytoplasmic aspartoacylase (ASPA), building the so called NAA pathway [3–7]. Several studies linked NAA to neuronal osmoregulation, lipid synthesis and energy metabolism [8, 9]. We were the first to show that the NAA pathway functionally exists in (brown) adipose tissue [5]. Further, we demonstrated that manipulation of the NAA pathway impacts brown adipocyte lipid turnover (lipogenesis and lipolysis), brown marker gene expression, and cellular respiration in vitro [5] and in vivo, thereby impacting whole body energy metabolism (unpublished).

NAT8L (N-acetyltransferase 8-like) accelerates lipid turnover and increases energy expenditure in brown adipocytes.

NAT8L (N-acetyltransferase 8-like) catalyzes the formation of N-acetylaspartate (NAA) from acetyl-CoA and aspartate. In the brain, NAA delivers the acetate moiety for synthesis of acetyl-CoA that is further used for fatty acid generation. However, its function in other tissues remained elusive. Here, we show for the first time that Nat8l is highly expressed in adipose tissues and murine and hum...

Bridging the gap between non-targeted stable isotope labeling and metabolic flux analysis

BACKGROUND Metabolism gained increasing interest for the understanding of diseases and to pinpoint therapeutic intervention points. However, classical metabolomics techniques only provide a very static view on metabolism. Metabolic flux analysis methods, on the other hand, are highly targeted and require detailed knowledge on metabolism beforehand. RESULTS We present a novel workflow to analy...

Striatal N-Acetylaspartate Synthetase Shati/Nat8l Regulates Depression-Like Behaviors via mGluR3-Mediated Serotonergic Suppression in Mice

Background Several clinical studies have suggested that N-acetylaspartate and N-acetylaspartylglutamate levels in the human brain are associated with various psychiatric disorders, including major depressive disorder. We have previously identified Shati/Nat8l, an N-acetyltransferase, in the brain using an animal model of psychosis. Shati/Nat8l synthesizes N-acetylaspartate from L-aspartate and ...

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...
