KYNA Ameliorates Hepatic Ischemia–Reperfusion Injury by Activating the Hippo Signalling Pathway via FTO‐Dependent m6A Demethylation of LATS1

Cell Proliferation, EarlyView.
Our study elucidates the cellular and molecular mechanisms underlying KYNA's protective effects against HIRI. It emphasises that KYNA modulates the methylation status of the Hippo signalling pathway through the activation of AHR, thereby mitigating damage by promoting LATS1 degradation and facilitating the nuclear translocation of YAP. ABSTRACT Hepatic

Stimulatory effect of repeated treatment with lipopolysaccharide on a key enzyme of the kynurenine pathway in both genders in rats

European Pharmaceutical Journal, 2016
The neuroprotective or neurotoxic effects of the products of the kynurenine pathway of tryptophan metabolism highly depend on the action of kynurenine-3-monooxygenase (KMO).

Tryptophan Suppresses FTH1‐Driven Ferritinophagy, a Key Correlate of Prognosis in Hepatocellular Carcinoma

Cell Proliferation, EarlyView.
Intracellular tryptophan levels modulate selective autophagy of FTH1 via the NCOA4 pathway. This autophagic process then inhibits 6‐HMT synthesis, which then results in an increase in reactive oxygen species and ferroptosis. ABSTRACT Hepatocellular carcinoma (HCC) remains a lethal malignancy with limited therapeutic options.

Characteristic Features of Kynurenine Aminotransferase Allosterically Regulated by (Alpha)-Ketoglutarate in Cooperation with Kynurenine

PLoS ONE, 2012
Kynurenine aminotransferase from Pyrococcus horikoshii OT3 (PhKAT), which is a homodimeric protein, catalyzes the conversion of kynurenine (KYN) to kynurenic acid (KYNA). We analyzed the transaminase reaction mechanisms of this protein with pyridoxal-5'-phosphate (PLP), KYN and α-ketoglutaric acid (2OG) or oxaloacetic acid (OXA).

The Plasma [Kynurenine]/[Tryptophan] Ratio and Indoleamine 2,3-Dioxygenase: Time for Appraisal

International Journal of Tryptophan Research, 2019
The plasma kynurenine to tryptophan ([Kyn]/[Trp]) ratio is frequently used to express or reflect the activity of the extrahepatic Trp-degrading enzyme indoleamine 2,3-dioxygenase (IDO).

Stress exposure in the mdx mouse model of Duchenne muscular dystrophy provokes a widespread metabolic response

The FEBS Journal, EarlyView.
A targeted mass spectrometry‐based metabolomics assay was conducted to identify the impact of stress exposure on the regulation of biological stress pathways in the mdx mouse model of Duchenne muscular dystrophy. We demonstrated a broad shift in the circulating stress‐relevant plasma metabolome associated with stressful scruff handling that was ...

Identification of kynurenine and quinolinic acid as promising serum biomarkers for drug-induced interstitial lung diseases

Respiratory Research
Background Drug-induced interstitial lung disease (DILD) is a lung injury caused by various types of drugs and is a serious problem in both clinical practice and drug development.

The molecular mechanisms of defensive‐grade organic acid biosynthesis in ground beetles

Insect Molecular Biology, EarlyView.
Formic acid and methacrylic acid are the primary defensive chemicals in the pygidial gland secretions of Platynus angustatus and Pterostichus moestus, respectively. Comparative transcriptomics suggests the folate cycle and valine catabolism may be involved in the biosynthesis of formic acid and methacrylic acid, respectively.
