Species Differences in Tryptophan Metabolism and Disposition

International Journal of Tryptophan Research, 2022
Major species differences in tryptophan (Trp) metabolism and disposition exist with important physiological, functional and toxicity implications. Unlike mammalian and other species in which plasma Trp exists largely bound to albumin, teleosts and other ...

Microneedle‐Based Biofertilizer Delivery Improves Plant Growth Through Microbiome Engineering

Advanced Functional Materials, EarlyView.
This figure shows how microneedles are used to deliver biofertilizers to enhance plant growth through microbial migration, metabolic reprogramming, and changes in plant endogenous microbiome. Abstract This study presents a microneedle‐based system for the delivery of rhizospheric biofertilizers into plant tissues to enhance growth.

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.

Host and gut microbial tryptophan metabolism and type 2 diabetes: an integrative analysis of host genetics, diet, gut microbiome and circulating metabolites in cohort studies

Gut, 2021
Objective Tryptophan can be catabolised to various metabolites through host kynurenine and microbial indole pathways. We aimed to examine relationships of host and microbial tryptophan metabolites with incident type 2 diabetes (T2D), host genetics, diet ...

Novel Bioconjugate Materials: Synthesis, Characterization and Medical Applications

Advanced Healthcare Materials, EarlyView.
This review discusses the bioconjugation of novel materials grouped under “biological”, “hybrid” and “synthetic” categories. Medical applications ranging from cancer therapy and diagnostics to optogenetics and tissue engineering are explored, and conjugation trends are highlighted as a general guide. The review concludes with a comparison of techniques

Using High‐Throughput Screening to Identify Crosslinking Peptides That Control Cell‐Mediated Matrix Degradation

Advanced Healthcare Materials, EarlyView.
Protease‐degradable hydrogels mimic dynamic cell‐matrix interactions, but controlling hydrogel degradation is a challenge. We screen libraries of peptides to identify sequences that are primarily degraded by membrane‐localized proteases. Crosslinking hydrogels with these peptides enables cell to spread and migrate while reducing matrix degradation ...

Leucine and tryptophan metabolism in rats [PDF]

Biochemical Journal, 1985
The rate of tryptophan metabolism in isolated liver cells from animals fed on a high-leucine diet was greater than for cells from control animals. Leucine inhibited tryptophan metabolism and tryptophan uptake in isolated liver cells, probably by competing for membrane transport. Leucine had no effect on tryptophan 2,3-dioxygenase in vitro.
