A transient inflammatory response contributes to oxaliplatin neurotoxicity in mice

Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1985-1998, December 2022., 2022
Abstract Objectives Peripheral neuropathy is a relevant dose‐limiting adverse event that can affect up to 90% of oncologic patients with colorectal cancer receiving oxaliplatin treatment. The severity of neurotoxicity often leads to dose reduction or even premature cessation of chemotherapy.

Unprecedented Combination of Polyketide Natural Product Fragments Identifies the New Hedgehog Signaling Pathway Inhibitor Grismonone

Chemistry – A European Journal, Volume 28, Issue 67, December 1, 2022., 2022
The chemical evolution of polyketide natural products leads to the unprecedented combination of biosynthetically related fragments in arrangements not found in Nature. The pseudo‐natural product grismonone was identified to be a potent inhibitor of Hedgehog signaling – a bioactivity that is not shared by its guiding fragments.

Exercise training restores longevity-associated tryptophan metabolite 3-hydroxyanthranilic acid levels in middle-aged adults. [PDF]

Acta Physiol (Oxf)
Abstract Aim Recent pre‐clinical evidence suggests that the tryptophan metabolite 3‐hydroxyanthranilic acid (3‐HAA) and the related enzyme activity along the kynurenine metabolic pathway (KP) are associated with lifespan extension. We aimed to translate these findings into humans and expose exercise training as a potential non‐pharmacological ...

Gut microbiota‐stem cell niche crosstalk: A new territory for maintaining intestinal homeostasis

iMeta, Volume 1, Issue 4, December 2022., 2022
Intestinal stem cells (ISCs) are protected by their niche and are regulated by Wnt, bone morphogenetic protein, and Notch. ISCs and their relationship with intestinal microbiota provide a feasible pathway to alleviate intestinal diseases. Diverse bacteria‐related postbiotics regulate ISCs and maintain their homeostasis.

Post-Bariatric Surgery Changes in Quinolinic and Xanthurenic Acid Concentrations Are Associated with Glucose Homeostasis. [PDF]

PLoS ONE, 2016
BACKGROUND:An increase of plasma kynurenine concentrations, potentially bioactive metabolites of tryptophan, was found in subjects with obesity, resulting from low-grade inflammation of the white adipose tissue.

Kynurenines and Neurofilament Light Chain in Multiple Sclerosis

Frontiers in Neuroscience, 2021
Multiple sclerosis is an autoimmune, demyelinating, and neurodegenerative disease of the central nervous system. In recent years, it has been proven that the kynurenine system plays a significant role in the development of several nervous system ...

RETRACTED ARTICLE: Kynurenine promotes neonatal heart regeneration by stimulating cardiomyocyte proliferation and cardiac angiogenesis

Nature Communications, 2022
Indoleamine 2,3 dioxygenase-1 (IDO1) catalyzes tryptophan-kynurenine metabolism in many inflammatory and cancer diseases. Of note, acute inflammation that occurs immediately after heart injury is essential for neonatal cardiomyocyte proliferation and ...

Brain Kynurenine Pathway Metabolite Levels May Reflect Extent of Neuroinflammation in ALS, FTD and Early Onset AD

Pharmaceuticals, 2023
Objectives: Despite distinct clinical profiles, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) patients share a remarkable portion of pathological features, with a substantial percentage of patients displaying a mixed disease ...

Kynurenine induces T cell fat catabolism and has limited suppressive effects in vivo

EBioMedicine, 2021
Background: L-kynurenine is a tryptophan-derived immunosuppressive metabolite and precursor to neurotoxic anthranilate and quinolinate. We evaluated the stereoisomer D-kynurenine as an immunosuppressive therapeutic which is hypothesized to produce less ...
