Selenomethionine metabolism and its toxicity in yeast

open access: yesBiomolecular Concepts, 2013
The importance of selenium for organisms can be explained by its existence as selenocysteine in the catalytic centers of glutathione peroxidase and thioredoxin reductase. Another selenoamino acid, selenomethionine, is the major form of selenium in foods,

Selenomethionine as a dual-mechanism ferroptosis inhibitor: selenium-supply-driven GPX4 biosynthesis beyond transsulfuration and reductive-capacity-mediated ROS scavenging independent of GPX4 activity [PDF]

open access: yesCell Death and Disease
Ferroptosis is an iron-dependent form of nonapoptotic cell death driven by lipid peroxidation. The selenium-dependent glutathione peroxidase 4 (GPX4) serves as the central regulator of ferroptosis through enzymatic reduction of phospholipid ...

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference
