The Influence of Kynurenine and Its Metabolites on Lipid Metabolism

Pteridines, 1997
Incorporation of fatty acids into phospholipids has been investigated using samples of rat liver tissue homogenate, Krebs-Ringer-phosphate buffer (pH=7.4) containing 0.3% albumin, fatty acid mixture and glycerol.

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.

Melatonin reduces oxidative neurotoxicity due to quinolinic acid: In vitro and in vivo findings

, 2000
The in vivo and in vitro effects of melatonin on quinolinic acid-induced oxidative damage in rat brain were determined. The concentrations of malonaldehyde and 4-hydroxyalkenals were assayed as an index of oxidatively damaged lipid.

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.

NAD Kinase by Quinolinic Acid

, 2003
NADP is essential for biosynthetic pathways, energy, and signal transduction. In living organisms, NADP biosynthesis proceeds through the phosphorylation of NAD with a reaction catalyzed by NAD kinase.

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 ...
