Epigenetic regulation by ketone bodies in cardiac diseases and repair
Bibliographic record
Abstract
Ketone bodies, particularly β-hydroxybutyrate (BHB), play an important role in the epigenetic regulation of gene expression in cardiac tissues, impacting both cardiac health and disease. This review explores the multifaceted influence of ketone bodies on epigenetic mechanisms, including histone acetylation, DNA methylation, ubiquitination, sirtuins activation, and RNA modulation. By acting as endogenous histone deacetylase inhibitors, ketone bodies enhance histone acetylation, thereby promoting the expression of genes involved in antioxidant defenses, anti-inflammatory responses, and metabolic regulation. Furthermore, BHB affects DNA methylation patterns by altering the availability of key metabolites such as S-adenosylmethionine. Ketogenic diet, which elevates BHB levels, has been shown to modulate gene expression, such as increasing FOXO3a and metallothionein 2, and improve cardiac function. This review highlights the therapeutic potential of ketone bodies in managing cardiac diseases through their epigenetic effects, underscoring the need for further research to elucidate the detailed molecular pathways and long-term impacts of these metabolic interventions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
