Endothelial arginine resynthesis contributes to the maintenance of vasomotor function in male diabetic mice. [PDF]

PLoS ONE, 2014
Argininosuccinate synthetase (ASS) is essential for recycling L-citrulline, the by-product of NO synthase (NOS), to the NOS substrate L-arginine. Here, we assessed whether disturbed arginine resynthesis modulates endothelium-dependent vasodilatation in ...

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

Advanced Science, Volume 13, Issue 58, 19 October 2026.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Supporting your practice: Compounding sodium benzoate oral liquid for urea cycle disorders

, 2021
Urea cycle disorders (UCD) are rare inherited metabolic disorders with an incidence estimated to be 1: 35,000 births. UCDs are caused by the dysfunction of any of the six enzymes (namely, carbamoyl phosphate synthetase I, N-acetylglutamate synthetase ...

Fumarate and Its Esters: Physiology, Pathology, Molecular Mechanisms, Diseases, and Therapy

MedComm, Volume 7, Issue 10, October 2026.
Fumarate is an endogenous immunometabolite that regulates metabolism, redox homeostasis, and inflammation. Although fumaric acid esters (FAEs) share several molecular targets with fumarate, their distinct physicochemical properties confer unique biological activities and therapeutic applications.

Modulation of intestinal urea cycle by dietary spermine in suckling rat

, 2005
peer reviewedArgininosuccinate synthetase, an ubiquitous enzyme in mammals, catalyses the formation of argininosuccinate, the precursor of arginine. Arginine is recognised as an essential amino acid in foetuses and neonates, but also as a conditionally ...

Overcoming resistance to arginine deprivation therapy using GC7 in pleural mesothelioma

iScience
Summary: Pleural mesothelioma is a highly chemotherapy-resistant cancer. Approximately 50% of mesotheliomas do not express argininosuccinate synthetase 1 (ASS1), the rate-limiting enzyme in arginine biosynthesis, making arginine depletion with pegylated ...

The pathway for urea cycle derived from KEGG pathway analysis.

, 2016
UM_WWY possess a gene encoding for a putative enzyme arginase (EC 3.5.3.1) which hydrolyzes arginine into ornithine and urea. EC 6.3.4.5 = Argininosuccinate synthetase; EC 4.3.2.1 = Argininosuccinate lyase; EC 2.1.3.3 = Ornithine transcarbamoylase.

Data from A Phase I Study of Pegylated Arginine Deiminase (Pegargiminase), Cisplatin, and Pemetrexed in Argininosuccinate Synthetase 1-Deficient Recurrent High-grade Glioma

, 2023
<div>AbstractPurpose:<p>Patients with recurrent high-grade gliomas (HGG) are usually managed with alkylating chemotherapy ± bevacizumab. However, prognosis remains very poor. Preclinically, we showed that HGGs are a target for arginine depletion with pegargiminase (ADI-PEG20) due to epimutations of argininosuccinate synthetase (<i> ...
