1 · What the graph read from it

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.

2 · The registry

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

Exposure to low levels of environmental challenges, known as hormetic stress, fosters subsequent stress resistance and promotes healthy aging in later life. However, specific mechanisms governing transcriptional reprogramming upon hormetic nutrient stress remain elusive. Here, we identify histone H3 lysine 27 acetylation (H3K27ac) as a crucial driver of transcriptomic adaptation to hormetic fasting. Beyond its immediate function of enhancing lipid catabolism for alternative energy sources, stress-induced H3K27ac activates lifelong antioxidant defenses, thereby reducing reactive oxygen species (ROS) produced by stress-induced fatty acid oxidation and their accumulation during aging. Induced H3K27ac at metabolic genes, mediated by the pioneer factor PHA-4/FOXA, the cooperating transcription factor NHR-49/HNF4, and the nucleoporin 50 (NPP-16/NUP50), is crucial for lifespan extension under hormetic nutrient stress in Caenorhabditis elegans. Our findings establish H3K27ac as a key transcriptional switch bridging nutrient status with transcriptomic reprogramming, underpinning the longevity of hormetic fasting through orchestrating lipid catabolism and antioxidant defenses.
