Narrative review of mechanistic and clinical literature without systematic search methodology
PubMed 38299513 · doi:10.1089/ars.2023.0285
What was done
This narrative review synthesizes basic and clinical literature on the roles of selenium and selenoproteins, including glutathione peroxidase, thioredoxin reductase, and endoplasmic reticulum-localized selenoproteins, in cardiovascular redox balance, calcium signaling, and cardiac pathophysiology.
What was found
The abstract reports no quantitative data or numerical outcomes. It states that selenoproteins serve as primary enzymatic antioxidant defenses in the heart and notes that dysregulated redox stress from inefficient removal of reactive species contributes to inflammation, mitochondrial dysfunction, endoplasmic reticulum stress, and cardiovascular disease progression.
Why it matters
This paper summarizes the mechanistic roles of selenoproteins, especially emerging endoplasmic reticulum-resident variants, in myocardial redox regulation and discusses their potential as diagnostic and therapeutic targets.
Limits
As a narrative review, the paper presents no original experimental data, sample sizes, or systematic search methodology. The clinical utility and therapeutic interventions discussed remain unverified by primary clinical trials in this abstract.
