Higher Circulating Kynurenine Levels Linked to Higher Risk of Sarcopenia in Older Adults: A Cohort Study and UK Biobank Analysis [PDF]

Endocrinology and Metabolism
Background While experimental studies show kynurenine, a tryptophan metabolite, drives muscle catabolism through pro-oxidative and inflammatory mechanisms, clinical evidence linking circulating kynurenine to sarcopenia in humans remains scarce.

IFNγ-INDUCED KINURENINE PRODUCTION AND INDOLAMINE 2,3-DIOXYGENASE GENE EXPRESSION IN PSORIASIS

Медицинская иммунология, 2014
. An alternative pathway of L-tryptophan biotransformation is provided by the indolamine 2,3-dioxygenase (INDO), and it results into synthesis of kynurenine and other «distal» metabolites, playing a pivotal role in immunoregulation and down-regulation of

A history of suicide attempts among individuals with schizophrenia is associated with tryptophan degradation via the salivary kynurenine pathway

BMC Psychiatry
Background Tryptophan, an essential precursor metabolite within the kynurenine pathway, has been implicated in the neurobiological mechanisms underlying both schizophrenia and associated suicidality. Despite this link, the lack of validated biomarkers to

Immunometabolic Network Interactions of the Kynurenine Pathway in Cutaneous Malignant Melanoma

Frontiers in Oncology, 2020
Dysregulation of the kynurenine pathway has been regarded as a mechanism of tumor immune escape by the enzymatic activity of indoleamine 2, 3 dioxygenase and kynurenine production. However, the immune-modulatory properties of other kynurenine metabolites

Tryptophan regulates the expression of IGFBP1 in bovine endometrial epithelial cells in vitro via the TDO2-AHR pathway

BMC Veterinary Research
Background This study aimed to identify the roles of L-tryptophan (Trp) and its rate-limiting enzymes on the receptivity of bovine endometrial epithelial cells. Real-time PCR was conducted to analyze the differential expression of genes between different

Kynurenine Promotes Phosphate-Induced Endothelial Calcification via Endothelial-to-Mesenchymal Transition, Osteoblastic Differentiation and AhR Activation

Toxins
In end-stage renal disease (ESRD), the accumulation of solutes normally excreted by the kidneys contributes to multiple complications, including vascular calcification (VC), a key factor in the heightened cardiovascular risk seen in these patients. Among
