Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

open access: yesAnimal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

Activation of Nrf2 by Electrophiles Is Largely Independent of the Selenium Status of HepG2 Cells

open access: yesAntioxidants, 2021
Selenoenzymes, whose activity depends on adequate selenium (Se) supply, and phase II enzymes, encoded by target genes of nuclear factor erythroid 2-related factor 2 (Nrf2), take part in governing cellular redox homeostasis.

MDL‐800‐induced SIRT6 activation decreases age‐associated osteoarthritis in mice

open access: yesArthritis &Rheumatology, Accepted Article.
Objective SIRT6 is a nuclear‐localized histone deacetylase that regulates multiple pathways associated with aging. This study aimed to determine whether systemic administration of a small molecule activator of SIRT6, MDL‐800, decreases the severity of age‐associated osteoarthritis (OA) in mice.

deep-Sep: a deep learning-based method for fast and accurate prediction of selenoprotein genes in bacteria

open access: yesmSystems
Selenoproteins are a special group of proteins with major roles in cellular antioxidant defense. They contain the 21st amino acid selenocysteine (Sec) in the active sites, which is encoded by an in-frame UGA codon.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

open access: yesBMEMat, EarlyView.
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 ...

Disruption of Selenium Handling During Puberty Causes Sex-Specific Neurological Impairments in Mice

open access: yesAntioxidants, 2019
Selenium is an essential trace element linked to normal development and antioxidant defense mechanisms through its incorporation into selenoproteins via the amino acid, selenocysteine (Sec).

Heat stress in spermatogenesis: a redox‐dependent decision network linking ROS, autophagy, and regulated cell death

open access: yesBiological Reviews, EarlyView.
ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

The Intrinsically Disordered Membrane Enzymes Selenoprotein S and Selenoprotein K [PDF]

open access: yesBiophysical Journal, 2015
Selenoproteins constitute a family of enzymes involved in the management and regulation of reactive oxygen species, signaling molecules that are also affiliated with molecular damage and disease. The family contains two intrinsically disordered membrane proteins: selenoprotein S (SelS) and selenoprotein K (SelK). Both of these bitopic membrane proteins

Selenium and selenoprotein P1 levels are related to primary open-angle glaucoma [PDF]

open access: yesJournal of Medical Biochemistry, 2014
Background: Glaucoma is a highly prevalent eye disease related to optic nerve lesions and visual field defects. Primary Open-Angle Glaucoma (POAG) is a type of glaucoma that occurs frequently with unknown etiology.
