Selenium, Selenoproteins, and Immunity [PDF]

Nutrients, 2018
Selenium is an essential micronutrient that plays a crucial role in development and a wide variety of physiological processes including effect immune responses. The immune system relies on adequate dietary selenium intake and this nutrient exerts its biological effects mostly through its incorporation into selenoproteins. The selenoproteome contains 25

Metabolic Memory in Cardiovascular Disease: Encoding, Propagation, and Therapeutic Targeting

Advanced Science, EarlyView.
Cardiovascular risk often persists after metabolic abnormalities are corrected. This conceptual Review frames such persistence as metabolic memory, encoded through a narrowing therapeutic window from reversible marks to irreversible damage, with continuous input from peripheral organs.

Evolution of selenoproteins in the metazoan [PDF]

BMC Genomics, 2012
Abstract Background The selenocysteine (Sec) containing proteins, selenoproteins, are an important group of proteins present throughout all 3 kingdoms of life. With the rapid progression of selenoprotein research in the post-genomic era, application of bioinformatics methods to the identification of selenoproteins in ...

A Versatile Strategy to Reduce UGA-Selenocysteine Recoding Efficiency of the Ribosome Using CRISPR-Cas9-Viral-Like-Particles Targeting Selenocysteine-tRNA^[Ser]Sec Gene

Cells, 2019
The translation of selenoprotein mRNAs involves a non-canonical ribosomal event in which an in-frame UGA is recoded as a selenocysteine (Sec) codon instead of being read as a stop codon.

Natural‐Inspired Engineered Microalgae With Selenium Enrichment Enabled Potent Anti‐Tumor Immunity

Advanced Science, EarlyView.
Se‐Ssp was engineered as a potent immunomodulator for activating innate immunity via the TLR and cGAS‐STING pathways, therefore converting “cold” tumors into “hot” tumors to achieve high efficacy and long‐term therapeutic outcomes. ABSTRACT Immunotherapy has shed light on clinical oncology for several decades.

LRP8‐mediated selenocysteine uptake is a targetable vulnerability in MYCN‐amplified neuroblastoma

EMBO Molecular Medicine, 2023
Ferroptosis has emerged as an attractive strategy in cancer therapy. Understanding the operational networks regulating ferroptosis may unravel vulnerabilities that could be harnessed for therapeutic benefit. Using CRISPR‐activation screens in ferroptosis

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,

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.

Knockdown of selenocysteine-specific elongation factor in Amblyomma maculatum alters the pathogen burden of Rickettsia parkeri with epigenetic control by the Sin3 histone deacetylase corepressor complex.

PLoS ONE, 2013
Selenocysteine is the 21st naturally-occurring amino acid. Selenoproteins have diverse functions and many remain uncharacterized, but they are typically associated with antioxidant activity.
