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

Chronic hepatitis C virus (HCV) infection is responsible for severe liver diseases including liver cirrhosis and hepatocellular carcinoma. An HCV non-structural protein 4B (NS4B) plays an essential role in viral RNA genome replication by building multi-vesicular structures around endoplasmic reticulum membranes. Especially, the second amphipathic helix of NS4B (NS4B-AH2) was shown to be essential for this process. By screening compounds against a membrane-aggregating activity of NS4B-AH2, several anti-HCV replication small molecules targeting NS4B-AH2 were discovered. However, little is known about detailed molecular mechanism of action for these NS4B-AH2 inhibitors. In this report, we provide evidences that NS4B-AH2 is required for NS4B's dimerization/multimerization, its proper subcellular localization, as well as its interaction with NS5A. More importantly, one of NS4B-AH2 inhibitors called "anguizole" was found to be able to disrupt all of these NS4B-AH2-mediated biological functions of NS4B. This newly elucidated mechanism of action will enable us not only to better understand a central role of NS4B-AH2 in HCV life cycle but also to develop a more safe and effective new class of NS4B-AH2 inhibitors of HCV replication in the future.
