Targeted Restoration of the Microbial Tryptophan Oxidative Pathway Ameliorates Autism‐Like Behavioral and Synaptic Deficits

Advanced Science, EarlyView.
ABSTRACT Autism Spectrum Disorder (ASD) is associated with gut microbiota dysbiosis, yet the contribution of specific microbial metabolic pathways remains unclear. Reanalysis of a public ASD cohort revealed reduced functional potential in microbial tryptophan oxidative metabolism.

Biochemically Constrained Multi‐Omics Integration Reveals Protein–Metabolite Dependencies Across Diseases

Advanced Science, EarlyView.
ProMetNet introduces a biologically constrained deep learning framework for proteo‐metabolomic integration by embedding Reactome‐derived pathway topology into neural networks. It captures non‐linear molecular dependencies and pathway‐level metabolic reorganization, enabling interpretable discrimination.

Quinolinic acid: neurotoxicity [PDF]

The FEBS Journal, 2012
This minireview series reviews some of the most recent findings about quinolinic acid's cellular toxicity and its implications in diseases such as HIV associated neurocognitive disorders, depressive disorders and schizophrenia, and finally therapeutic strategies with drugs able to interfere with quinolinic acid production and/or effects.

Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

Advanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

Evidence for a synergistic action of glutaric acid 3-hydroxyglutaric acids disturbing rat brain energy metabolism

, 2007
Glutaric acidemia type I is an inherited metabolic disorder caused by a severe deficiency of the mitochondrial glutaryl-CoA dehydrogenase activity leading to accumulation of predominantly glutaric and 3-hydroxyglutaric acids in the brain tissue of the ...

System‐Local Axes and Metabolic Reprogramming From Health to Response in House Dust Mite‐Specific Subcutaneous Immunotherapy for Allergic Rhinitis

iMetaMed, EarlyView.
This study delineated nasal‐plasma metabolic reprogramming in house dust mite‐allergic rhinitis (HDM‐AR) and subcutaneous immunotherapy (SCIT) response, showing compartment‐specific signatures dominated by nasal lipid‐redox and plasma nucleotide‐NAD+ axes and across the HC–HDM‐AR–SCIT response continuum, dual‑compartment metabolites exhibited ...

The Endogenous Tryptophan Metabolite and NAD(+) Precursor Quinolinic Acid Confers Resistance of Gliomas to Oxidative Stress [PDF]

, 2013
Quinolinic acid is a product of tryptophan degradation and may serve as a precursor for NAD(+), an important enzymatic cofactor for enzymes such as the DNA repair protein PARP.
