ASS1 inhibits triple-negative breast cancer by regulating PHGDH stability and de novo serine synthesis

open access: yesCell Death and Disease
Argininosuccinate synthase (ASS1), a critical enzyme in the urea cycle, acts as a tumor suppressor in many cancers. To date, the anticancer mechanism of ASS1 has not been fully elucidated. Here, we found that phosphoglycerate dehydrogenase (PHGDH), a key

Adrenal hormones in the maintenance of glucose homeostasis during prolonged fasting in male glucagon‐deficient mice

open access: yesJournal of Diabetes Investigation, EarlyView.
Compensatory corticosterone‐mediated lipolysis and hepatic gluconeogenesis (via amino acids and glycerol) prevent hypoglycemia in GCGKO mice during prolonged fasting. ABSTRACT Aims/Introduction Glucagon is a key regulator of fasting glucose homeostasis, but the contribution of adrenal hormones during prolonged fasting remains unclear.

Effects of N‐Acetylcysteine on Oxidative Status and Intestinal Health in Piglets (Sus scrofa domesticus L.): A PRISMA‐Based Systematic Review

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Oxidative stress is a critical challenge in intensive swine production, particularly during weaning, compromising intestinal integrity and animal performance. N‐acetylcysteine (NAC) has emerged as a multifunctional nutritional strategy to mitigate these effects due to its role as a glutathione precursor and signaling modulator. This systematic

Intracellular arginine-dependent translation sensor reveals the dynamics of arginine starvation response and resistance in ASS1-negative cells

open access: yesCancer & Metabolism, 2021
Background Many cancers silence the metabolic enzyme argininosuccinate synthetase 1 (ASS1), the rate-limiting enzyme for arginine biosynthesis within the urea cycle. Consequently, ASS1-negative cells are susceptible to depletion of extracellular arginine

Functional identification of two novel variants and a hypomorphic variant in ASS1 from patients with Citrullinemia type I

open access: yesFrontiers in Genetics, 2023
Background: Citrullinemia type I (CTLN1) is a rare autosomal recessive inborn error of the urea cycle caused by mutations in the gene encoding the arginosuccinate synthetase (ASS1) enzyme.

Warburg redefined: Metabolites, mitochondria and macrophages in immune regulation

open access: yesThe 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).

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

open access: yesJournal 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

A Phase 1 study of ADI-PEG20 (pegargiminase) combined with cisplatin and pemetrexed in ASS1-negative metastatic uveal melanoma [PDF]

open access: yes, 2022
Metastatic uveal melanoma (UM) is a devastating disease with few treatment options. We evaluated the safety, tolerability and preliminary activity of arginine depletion using pegylated arginine deiminase (ADI-PEG20; pegargiminase) combined with ...

Arginine starvation impairs mitochondrial respiratory function in ASS1-Deficient breast cancer cells [PDF]

open access: yes, 2014
[[abstract]]Autophagy is the principal catabolic response to nutrient starvation and is necessary to clear dysfunctional or damaged organelles, but excessive autophagy can be cytotoxic or cytostatic and contributes to cell death.

Naturally-occurring spinosyn A and its derivatives function as argininosuccinate synthase activator and tumor inhibitor

open access: yesNature Communications, 2021
Arginine addiction induced by argininosuccinate synthase (ASSN1) deficiency has been exploited to treat ASS1-deficient cancers. Here, the authors show an alternative therapeutic approach where ASS1 activity is increased by the pesticide spinosyn A and is
