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

Expression of the herpes simplex virus type 1 (HSV-1) regulatory protein ICP0 in transfected cells reactivates rep gene expression from integrated adeno-associated virus (AAV) type 2 genomes via a mechanism that requires both its RING finger and USP7 interaction domains. In this study, we found that the rep reactivation defect of USP7-binding-negative ICP0 mutants can be overcome by further deletion of sequences in the C-terminal domain of ICP0, indicating that binding of USP7 to ICP0 is not directly required. Unlike the case in transfected cells, only the RING finger domain of ICP0 was essential for rep gene reactivation during HSV-1 infection. However, mutants unable to bind to USP7 activate HSV-1 gene expression and reactivate rep gene expression with reduced efficiencies. These results further elucidate the role of ICP0 as a helper factor for AAV replication and illustrate that care is required when extrapolating from the properties of ICP0 in transfection assays to events occurring during HSV-1 infection.
