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 adenovirus genome forms chromatin-like structure with viral core proteins. This complex supports only a low level of transcription in a cell-free system, and thus core proteins have been thought to be negative factors for transcription. The mechanism how the transcription from the viral DNA complexed with core proteins is activated in infected cells remains unclear. Here, we found that both core proteins and histones are bound with the viral DNA in early phases of infection. We also found that acetylation of histone H3 occurs at the promoter regions of viral active genes in a transcription-independent manner. In addition, when a plasmid DNA complexed with core proteins was introduced into cells, core proteins enhanced transcription. Knockdown of TAF-I, a remodeling factor for viral core protein-DNA complexes, reduces the enhancement effect by core proteins, indicating that core proteins positively regulate viral transcription through the interaction with TAF-I. We would propose a possible mechanism that core proteins ensure transcription by regulating viral chromatin structure through the interaction with TAF-I.
