RNAi-induced silencing of embryonic tryptophan oxygenase in the Pyralid moth, Plodia interpunctella [PDF]

open access: goldJournal of Insect Science, 2004
Gene silencing through the introduction of double-stranded RNA (RNA interference, RNAi) provides a powerful tool for the elucidation of gene function in many systems, including those where genomics and proteomics are incomplete.

Novel immune cell infiltration-related biomarkers in atherosclerosis diagnosis [PDF]

open access: yesPeerJ, 2023
Background Immune cell infiltration (ICI) has a close relationship with the progression of atherosclerosis (AS). Therefore, the current study was aimed to explore the role of genes related to ICI and to investigate potential mechanisms in AS.

Detoxification of Indole by an Indole-Induced Flavoprotein Oxygenase from Acinetobacter baumannii. [PDF]

open access: yesPLoS ONE, 2015
Indole, a derivative of the amino acid tryptophan, is a toxic signaling molecule, which can inhibit bacterial growth. To overcome indole-induced toxicity, many bacteria have developed enzymatic defense systems to convert indole to non-toxic, water ...

Beneficial or detrimental activity of regulatory T cells, indoleamine 2,3-dioxygenase, and heme oxygenase-1 in the lungs is influenced by the level of virulence of Mycobacterium tuberculosis strain infection

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
Tuberculosis (TB) caused by the complex Mycobacterium tuberculosis (Mtb) is the main cause of death by a single bacterial agent. Last year, TB was the second leading infectious killer after SARS-CoV-2.

HEME OXYGENASE-1 UPREGULATED BY MELATONIN: POTENTIAL PROTECTION AGAINST BURN-INDUCED OXIDATIVE GASTRIC MUCOSAL INJURY. [PDF]

open access: yesJournal of IMAB, 2015
Melatonin is indoleamine hormone derived from L-tryptophan. Due to its lipophilic nature, it is accessible to every cell. Melatonin has immunomodulatory and antioxidant activities thus protecting tissue injury.

Ultraviolet Nanophotonics Enables Autofluorescence Correlation Spectroscopy on Label-Free Proteins With a Single Tryptophan [PDF]

open access: yes, 2023
Using the ultraviolet autofluorescence of tryptophan aminoacids offers fascinating perspectives to study single proteins without the drawbacks of fluorescence labelling. However, the low autofluorescence signals have so far limited the UV detection to large proteins containing several tens of tryptophan residues.

Ultraviolet superradiance from mega-networks of tryptophan in biological architectures [PDF]

open access: yes, 2023
Networks of tryptophan -- an aromatic amino acid with strong fluorescent response -- are ubiquitous in biological systems, forming diverse architectures in transmembrane proteins, cytoskeletal filaments, sub-neuronal elements, photoreceptor complexes, virion capsids, and other cellular structures.

Tryptophan metabolism in tsetse flies and the consequences of its derangement

open access: yesMemorias do Instituto Oswaldo Cruz, 1987
Literature comparing salmon and wild type Glossina morsitans morsitans and that comparing tan and wild type Glossina palpalis palpalis is reviewed. New information is presented on behaviour and biochemistry of salmon and wild type G. m. morsitans.

Effects of pro-inflammatory cytokines on expression of kynurenine pathway enzymes in human dermal fibroblasts

open access: yesJournal of Inflammation, 2011
Background The kynurenine pathway (KP) is the main route of tryptophan degradation in the human body and generates several neuroactive and immunomodulatory metabolites.
