Ex Vivo Analysis of Tryptophan Metabolism Using 19F NMR. [PDF]

, 2019
Tryptophan, an essential amino acid, is metabolized into a variety of small molecules capable of impacting human physiology, and aberrant tryptophan metabolism has been linked to a number of diseases.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

The Kynurenine Pathway: a Proposed Mechanism Linking Diabetes and Periodontal Disease in Diabetic Patients

Dental Hypotheses, 2011
Introduction: Diabetes mellitus is a metabolic disease characte-rized by dysregulation of carbohydrate, protein and lipid metabolism. Diabetes could result, in part, in activation of tryptophan metabolism.

Circadian periodicity of tryptophan metabolism [PDF]

Journal of Clinical Investigation, 1968
Rhythmicity of tryptophan metabolism via the kynurenine pathway has been demonstrated in man. Normal subjects given 3 g of tryptophan at 0900 hours excreted almost three times the quantity of kynurenine, kynurenic acid, and xanthurenic acid than did subjects given the same dose at 2100 hours.

Tryptophan depletion increases nausea, headache and photophobia in migraine sufferers [PDF]

, 2006
Sensitivity to light was investigated 5 and 8 h after consumption of an amino acid drink which contained L-tryptophan (balanced amino acid condition: 19 controls and 22 migraine sufferers) or which produced a short-term reduction in brain serotonin ...

Evolution of substrate specificity in a recipient's enzyme following horizontal gene transfer [PDF]

, 2013
Despite the prominent role of horizontal gene transfer (HGT) in shaping bacterial metabolism, little is known about the impact of HGT on the evolution of enzyme function.

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
