Increased Tryptophan Metabolism Is Associated With Activity of Inflammatory Bowel Diseases.
Gastroenterology, 2017 BACKGROUND & AIMS Administration of tryptophan and some of its metabolites reduces the severity of colitis in mice, whereas removing tryptophan from the diet increases susceptibility to colitis.

In psychiatrically healthy individuals, overweight women but not men have lower tryptophan levels
Pteridines, 2015 Gender differences in tryptophan (TRP) breakdown in obese individuals have been previously reported. This could be both contributory to, as well as a consequence of, gender differences in mood changes among obese people.

On the origin of infrared bands attributed to tryptophan in Spitzer observations of IC 348 [PDF]
arXivInfrared emission features toward interstellar gas of the IC 348 star cluster in Perseus have been recently proposed to originate from the amino acid tryptophan. The assignment was based on laboratory infrared spectra of tryptophan pressed into pellets, a method which is known to cause large frequency shifts compared to the gas phase.

Use of a distant reporter group as evidence for a conformational change in a sensory receptor [PDF]
, 1977 A highly sensitive method for demonstrating ligand-induced conformational changes in protein molecules in solution is described. The method utilizes an environmentally sensitive reporter group that is known to be distant from the active site.

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).

Folate, neopterin and kynurenine pathway in patients with statin therapy
Pteridines, 2016 Statins, widely used antihyperlipidemic drugs, also have immunomodulatory properties independent from their lipid lowering effect. Even with slight modulations in the immune system, pteridine levels can display changes.

MYC promotes tryptophan uptake and metabolism by the kynurenine pathway in colon cancer
Genes & Development, 2019 In this study, Venkateswaran et al. investigated how the proto-oncogene MYC regulates the metabolism of amino acids other than glutamine in cancer.
