Vitamin B1 deficiency inhibits the increased conversion of tryptophan to nicotinamide in severe food-restricted rats.
Biosci. Biotechnol. Biochem. 79(1) , 103-8, (2015) The conversion of tryptophan (Trp) → nicotinamide (Nam) is an important pathway for supplying vitamin niacin. We reported the following two phenomena: (1) severe food restriction led to an increase in the Trp → Nam conversion compared with free-access control... |

The urinary ratio of 3-hydroxykynurenine/3-hydroxyanthranilic acid is an index to predicting the adverse effects of D-tryptophan in rats.
J. Nutr. Sci. Vitaminol. 60(4) , 261-8, (2014) The adverse effects of D-tryptophan and the possibility of it being a surrogate index for predicting adverse effects in rats were investigated. Male rats were fed one of several test diets (20% casein diets with 0% (control), 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% ... |

Organic anion transporting polypeptides 1B1 and 1B3 play an important role in uremic toxin handling and drug-uremic toxin interactions in the liver.
J. Pharm. Pharm. Sci. 17(4) , 475-84, (2015) Organic anion-transporting polypeptide (OATP) 1B1 and OATP1B3 contribute to hepatic uptake of numerous drugs. Thus, reduced OATP1B1 and OATP1B3 activity in chronic kidney disease (CKD) may have a major impact on the hepatic clearance of drugs. The effect of d... |

A single-run liquid chromatography mass spectrometry method to quantify neuroactive kynurenine pathway metabolites in rat plasma.
J. Pharm. Biomed. Anal. 107 , 426-31, (2015) Neuroactive metabolites in the kynurenine pathway of tryptophan catabolism are associated with neurodegenerative disorders. Tryptophan is transported across the blood-brain barrier and converted via the kynurenine pathway to N-formyl-L-kynurenine, which is fu... |

Effects of pro-inflammatory cytokines on expression of kynurenine pathway enzymes in human dermal fibroblasts.
J. Inflamm. (Lond.) 8 , 25, (2011) The kynurenine pathway (KP) is the main route of tryptophan degradation in the human body and generates several neuroactive and immunomodulatory metabolites. Altered levels of KP-metabolites have been observed in neuropsychiatric and neurodegenerative disorde... |

Inhibition of indoleamine 2,3-dioxygenase activity by levo-1-methyl tryptophan blocks gamma interferon-induced Chlamydia trachomatis persistence in human epithelial cells.
Infect. Immun. 79 , 4425-4437, (2011) Gamma interferon (IFN-γ) induces expression of the tryptophan-catabolizing enzyme indoleamine 2,3-dioxygenase (IDO1) in human epithelial cells, the permissive cells for the obligate intracellular bacterium Chlamydia trachomatis. IDO1 depletes tryptophan by ca... |

Targeting the kynurenine pathway-related alterations in Alzheimer's disease: a future therapeutic strategy.
J. Alzheimers Dis. 24 , 199-209, (2011) Alzheimer's disease (AD) is a chronic neurodegenerative disorder associated with dementia as a main feature. Despite decades of thorough research in the field of AD, the pathomechanism is still not fully understood. The development of novel experimental model... |

KynR, a Lrp/AsnC-type transcriptional regulator, directly controls the kynurenine pathway in Pseudomonas aeruginosa.
J. Bacteriol. 193(23) , 6567-75, (2011) The opportunistic pathogen Pseudomonas aeruginosa can utilize a variety of carbon sources and produces many secondary metabolites to help survive harsh environments. P. aeruginosa is part of a small group of bacteria that use the kynurenine pathway to catabol... |
