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

The association of DNA with histones in chromatin impedes DNA repair enzymes from accessing DNA lesions. Nucleosomes exist in a dynamic equilibrium in which portions of the DNA molecule spontaneously unwrap, transiently exposing buried DNA sites. Thus, nucleosome dynamics in certain regions of chromatin may provide the exposure time and space needed for efficient repair of buried DNA lesions. We have used FRET and restriction enzyme accessibility to study nucleosome dynamics following DNA damage by UV radiation. We find that FRET efficiency is reduced in a dose-dependent manner, showing that the presence of UV photoproducts enhances spontaneous unwrapping of DNA from histones. Furthermore, this UV-induced shift in unwrapping dynamics is associated with increased restriction enzyme accessibility of histone-bound DNA after UV treatment. Surprisingly, the increased unwrapping dynamics is even observed in nucleosome core particles containing a single UV lesion at a specific site. These results highlight the potential for increased "intrinsic exposure" of nucleosome-associated DNA lesions in chromatin to repair proteins.
