The Role of Exercise in Regulating Histone Modifications and Non-coding RNAs in Muscle Aging and Sarcopenia.
Review in Biochemical genetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Sarcopenia, the progressive loss of skeletal muscle mass and function with age, is a major contributor to frailty and decreased quality of life in older adults. While physical exercise remains the most effective intervention, its molecular mechanisms of action are not fully understood. Emerging evidence highlights the central role of epigenetic regulation-including histone modifications and non-coding RNAs (ncRNAs)-in mediating both the pathogenesis of sarcopenia and the adaptive responses to exercise. This review synthesizes current findings on how aging disrupts the epigenetic landscape of skeletal muscle, fostering anabolic resistance, inflammation, and impaired regeneration. We explore how exercise reverses these effects by modulating histone acetylation, methylation, and the novel mark of lactylation, thereby reactivating key genes involved in muscle maintenance and repair. Additionally, we detail how specific microRNAs and long non-coding RNAs contribute to muscle plasticity, and how their dysregulation underlies age-related functional decline. Importantly, we emphasize the interplay between histone modifiers and ncRNAs, and the translational evidence from human trials supporting exercise as an epigenetic reprogramming agent. Although human evidence is limited compared to animal models, emerging clinical studies in older adults demonstrate that resistance and endurance training modulate histone acetylation/methylation and miRNA profiles, with dose-dependent benefits on muscle function and epigenetic markers (e.g., reduced epigenetic age acceleration via methylation clocks in active elderly). These insights offer promising avenues for therapeutic strategies aimed at extending healthspan and combating sarcopenia in aging populations.
