Cloning and Expression of Cellular Glutathione Peroxidase (GPX1) in Japanese Quail (Coturnix japonica)

The Journal of Poultry Science, 2009
Glutathione peroxidase 1 (cellular glutathione peroxidase, EC 1.11.1.9 (GPX1)) is an antioxidant enzyme that plays an important role in scavenging reactive oxygen species to protect cells from oxidative damage.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Efficiency of Mammalian Selenocysteine Incorporation [PDF]

Journal of Biological Chemistry, 2004
Five components have thus far been identified that are necessary for the incorporation of selenocysteine (Sec) into approximately 25 mammalian proteins. Two of these are cis sequences, a SECIS element in the 3'-untranslated region and a Sec codon (UGA) in the coding region.

Biological Effects of Selenium‐Containing Ionic Liquids: Cytotoxicity, Mercury Interaction, and Antiproliferative Activity in Glioblastoma Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Selenium (Se) is an essential micronutrient that participates in redox regulation and cellular homeostasis. Selenium‐containing ionic liquids (ILsSe) have emerged as hybrid compounds combining the properties of organoselenium molecules with the tunable features of ionic liquids.

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Dietary interventions in acute kidney injury: From molecular mechanism to clinical trials

Experimental Physiology, EarlyView.
Abstract Ageing impairs renal resilience with an elevated risk of frequent and harmful acute kidney injury (AKI) that causes substantial morbidity and mortality among hospitalized patients. Since different damaging stimuli at the molecular, cellular and functional level contribute to this loss in kidney function, AKI's pathophysiology is heterogeneous ...

Synthesis of Oligonucleotide Conjugates Employing a Diselenide Linker

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
ABSTRACT In this study, we report the synthesis of an alkylene linker containing a terminal 2‐cyanoethyl protected selenium functionality for coupling at the 5'‐end of an oligonucleotide by solid phase synthesis for the preparation of oligonucleotide conjugates.

Selenol Protecting Groups in Organic Chemistry: Special Emphasis on Selenocysteine Se-Protection in Solid Phase Peptide Synthesis

Molecules, 2011
The appearance of selenium in organic synthesis is relatively rare, and thus examples in the literature pertaining to the masking of its considerable reactivity are similarly uncommon.

Antioxidant Responses to Dietary Supplementation With Non‐Enriched and Selenium‐Enriched Mushrooms and Selenized Yeast in Piglets

Molecular Nutrition &Food Research, Volume 70, Issue 19, 15 October 2026.
The findings highlight tissue‐specific responses to dietary selenium supplementation, with hepatic antioxidant modulation occurring without changes in plasma parameters, while selenium deposition patterns differed among tissues, emphasizing the complex relationship between selenium sources, metabolism, and antioxidant defense.

Effect of selenium hyperaccumulation on the root endophytic and rhizosphere microbiome of two Astragalus species

Plant Biology, Volume 28, Issue 6, Page 1960-1972, October 2026.
Selenium hyperaccumulation has little impact on the overall microbiome diversity but rather affects interactions with key plant microbial mutualists, including rhizobia. Abstract Metal hyperaccumulation is prevalent throughout plant evolution, particularly in the legume family (Fabaceae), and acts as a presumed chemical defence against herbivory ...
