Going Forward and Back: The Complex Evolutionary History of the GPx
There is large diversity among glutathione peroxidase (GPx) enzymes regarding their function, structure, presence of the highly reactive selenocysteine (SeCys) residue, substrate usage, and reducing agent preference.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Selenium in the Treatment of Graves’ Hyperthyroidism and Eye Disease
Based on the role of oxidative stress in the pathogenesis of Graves’ hyperthyroidism (GH) and Graves’ Orbitopathy (GO), a therapy with the antioxidant agent selenium has been proposed and a number of studies have been performed, both in vitro and in vivo.

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid
The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐

Selenoproteins are a unique class of proteins that contain the 21st amino acid, selenocysteine (Sec). Addition of Sec into a protein is achieved by recoding of the UGA stop codon. All 25 mammalian selenoprotein mRNAs possess a 3′ UTR stem-loop structure,

Programmed Deviations of Ribosomes From Standard Decoding in Archaea
Genetic code decoding, initially considered to be universal and immutable, is now known to be flexible. In fact, in specific genes, ribosomes deviate from the standard translational rules in a programmed way, a phenomenon globally termed recoding ...

Synthesis of Oligonucleotide Conjugates Employing a Diselenide Linker
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.
