Regulation of reactive oxygen molecules in pakchoi by histone acetylation modifications under Cd stress.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Reactive oxygen species (ROS) are essential modulators of epigenetic modifications under abiotic stress. However, the mutual regulation mechanism of the two under cadmium (Cd) stress is unclear. In this work, we investigated this issue using Cd-stressed pakchoi seedlings treated with six epi-modification inhibitors (5-AC, RG108, TSA, CUDC101, AT13148, and H89) as experimental materials. The experimental data showed that Cd stress caused ROS accumulation and chromatin decondensation. Addition of low concentrations of epi-modification inhibitors increased histone acetylation modification levels, and effectively attenuated cell cycle arrest and DNA damage caused by Cd-induced ROS accumulation, where histone acetylation modification levels were co-regulated by histone acetyltransferase and deacetyltransferase gene transcription. Moreover, the addition of the antioxidant Thi enhanced this mitigating effect. Also, TSA addition at high concentrations could also increase Cd-induced ROS accumulation. Based on this, we propose that the ROS molecular pathway may be related to epigenetic regulation, and chromatin modification may affect ROS accumulation by regulating gene expression, providing a new perspective for studying the regulatory mechanism of epigenetic modification under abiotic stress.
