A new assay for argininosuccinate in urine samples by high performance liquid chromatography

, 1996
A rapid, sensitive and simple procedure has been developed for determination of argininosuccinate (ASA). The assay is based upon the enzymatic cleavage of ASA in the presence of excess of argininosuccinate lyase (ASAL), HPLC separation and UV-detection ...

Phylogenomics and Divergence Dating of Fungus-Farming Ants (Hymenoptera: Formicidae) of the Genera Sericomyrmex and Apterostigma. [PDF]

PLoS ONE, 2016
Fungus-farming ("attine") ants are model systems for studies of symbiosis, coevolution, and advanced eusociality. A New World clade of nearly 300 species in 15 genera, all attine ants cultivate fungal symbionts for food. In order to better understand the

Regulating Lipid Metabolism in Cancer: The Therapeutic Potential of Traditional Chinese Medicine

Phytotherapy Research, EarlyView.
By regulating the reprogramming of lipid metabolism in tumor cells, TCM provides a novel strategy for antitumor therapy with reduced toxicity and enhanced efficacy. ABSTRACT Lipid metabolic reprogramming is a key feature of tumor cells to adapt to the microenvironment and plays an important role in tumor growth, invasion, and metastasis.

Warburg redefined: Metabolites, mitochondria and macrophages in immune regulation

The Journal of Physiology, EarlyView.
Abstract figure legend Following pro‐inflammatory stimulation, macrophages undergo Warburg‐like metabolic rewiring that extends more than increased glycolysis. The non‐canonical functions of glycolytic enzymes and lactate accumulation control macrophage immune responses through multiple signalling pathways (a).

NITRIC OXIDE (NO), CITRULLINE - NO CYCLE ENZYMES, GLUTAMINE SYNTHETASE AND OXIDATIVE STRESS IN ANOXIA (HYPOBARIC HYPOXIA) AND REPERFUSION IN RAT BRAIN

International Journal of Medical Sciences, 2010
Nitric oxide is postulated to be involved in the pathophysiology of neurological disorders due to hypoxia/ anoxia in brain due to increased release of glutamate and activation of N-methyl-D-aspartate receptors.

Plant NAOGAT (ArgJ) Structure Reveals Mechanism of Ornithine Biosynthesis, Preference for Acetylornithine and Susceptibility to Mangotoxin

Plant, Cell &Environment, Volume 49, Issue 12, Page 10283-10300, December 2026.
ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Urea Cycle Related Amino Acids Measured in Dried Bloodspots Enable Long-Term In Vivo Monitoring and Therapeutic Adjustment

Metabolites, 2019
Background: Dried bloodspots are easy to collect and to transport to assess various metabolites, such as amino acids. Dried bloodspots are routinely used for diagnosis and monitoring of some inherited metabolic diseases.

Evaluation of the Neurodevelopmental Status for Urea Cycle Disorders: Based on Clinical Experience

Journal of Pediatric Research, 2023
Aim:Urea cycle disorders (UCD) still have poor neurological outcomes despite early diagnosis and treatment. We aimed to present the neurological outcomes of UCD patients and to determine the main simple and accessible factors affecting these outcomes ...

Essential Oral Single Nutritional Therapy Products for Inherited Metabolic Diseases: Evidence and Consensus Assessment Using a Modified Delphi Method

Journal of Inherited Metabolic Disease, Volume 49, Issue 6, November 2026.
ABSTRACT Nutritional therapy is critical in managing inherited metabolic diseases (IMDs), and includes specialized diets and single nutritional therapy products (sNTPs) such as vitamins, cofactors, and amino acids. Many sNTPs function as medicines, but are regulated as food (e.g., food supplements), which can limit access, reimbursement, and consistent

Argininosuccinate synthetase and argininosuccinate lyase: two ornithine cycle enzymes from Agaricus bisporus

, 2007
Accumulation of high quantities of urea in fruiting bodies is a known feature of larger basidiomycetes. Argininosuccinate synthetase (ASS) and argininosuccinate lyase (ASL) are two ornithine cycle enzymes catalysing the last two steps in the arginine ...
