Prospects for the use of synthetic organoselenium compounds for the correction of metabolic and immune status during vaccination with live attenuated vaccines against especially dangerous infections

Acta Biomedica Scientifica, 2021
This review article analyzes the data on the role of selenium in the regulation of the metabolic and immune status of a macroorganism. The data on endogenousfunctional selenium-containing molecules, which include selenocysteine, selenomethionine, and ...

Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

Advanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

Dual incorporation of non-canonical amino acids enables production of post-translationally modified selenoproteins

Frontiers in Molecular Biosciences, 2023
Post-translational modifications (PTMs) can occur on almost all amino acids in eukaryotes as a key mechanism for regulating protein function. The ability to study the role of these modifications in various biological processes requires techniques to ...

The GPX3‐VCAM1 Axis Gates Pro‐Fibrotic Tubule Cell Fate in Hyperuricemic Nephropathy

Advanced Science, EarlyView.
Hyperuricemia induces NLRP3 inflammasome signaling activation and downregulation of GPX3 in proximal tubular epithelial cells, leading to oxidative stress–driven VCAM1 upregulation, emergence of pro‐fibrotic proximal tubule cells, macrophage recruitment, and renal fibrosis.

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

Animal 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 ...

Modern concept of biological identification of selenoproteins

Regulatory Mechanisms in Biosystems, 2018
Humans possess 25 selenoproteins, approximately half of which are enzymes (selenoenzymes) required for preventing, regulating, or reversing oxidative damage, while others participate in providing calcium metabolism, thyroid hormone maintenance, protein ...

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

Arthritis &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.

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

BMEMat, 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 ...
