Selenium‐Containing Tea‐Derived Peptides Activate Alcohol Dehydrogenase and Ameliorate Alcohol‐Induced Liver Injury by Modulating Oxidative Stress Homeostasis

Food Frontiers, Volume 7, Issue 2, March 2026.
The graphical abstract summarizes the experimental workflow: (1) Preparation of selenium‐containing tea‐derived peptides (TSE‐PP) guided by ADH activation; (2) Purification and LC‐MS/MS identification of selenium‐modified peptides; (3) Molecular docking to reveal peptide‐ADH interactions; (4) Evaluation of hangover‐alleviating and hepatoprotective ...

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

Journal of Intelligent Medicine, Volume 3, Issue 1, Page 47-68, March 2026.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Naturally Occurring tRNAs With Non-canonical Structures

Frontiers in Microbiology, 2020
Transfer RNA (tRNA) is the central molecule in genetically encoded protein synthesis. Most tRNA species were found to be very similar in structure: the well-known cloverleaf secondary structure and L-shaped tertiary structure.

Genes for selenium dependent and independent formate dehydrogenase in the gut microbial communities of three lower, wood-feeding termites and a wood-feeding roach [PDF]

, 2011
The bacterial Wood-Ljungdahl pathway for CO_2-reductive acetogenesis is important for the nutritional mutualism occurring between wood-feeding insects and their hindgut microbiota. A key step in this pathway is the reduction of CO_2 to formate,

The C-terminal selenenylsulfide of extracellular/non-reduced thioredoxin reductase endows this protein with selectivity to small-molecule electrophilic reagents under oxidative conditions

Frontiers in Molecular Biosciences
Mammalian cytosolic thioredoxin reductase (TrxR1) serves as an antioxidant protein by transferring electrons from NADPH to various substrates. The action of TrxR1 is achieved via reversible changes between NADPH-reduced and non-reduced forms, which ...
