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

Viral protein R (Vpr) of human immunodeficiency virus type 1 (HIV-1) is an accessory protein that plays an important role in viral pathogenesis. This pathogenic activity of Vpr is related in part to its capacity to induce cell cycle G2 arrest and apoptosis of target T cells. A screening for multicopy suppressors of these Vpr activities in fission yeast identified heat shock protein 70 (Hsp70) as a suppressor of Vpr-induced cell cycle arrest. Hsp70 is a member of a family of molecular chaperones involved in innate immunity and protection from environmental stress. In this report, we demonstrate that HIV-1 infection induces Hsp70 in target cells. Overexpression of Hsp70 reduced the Vpr-dependent G2 arrest and apoptosis and also reduced replication of the Vpr-positive, but not Vpr-deficient, HIV-1. Suppression of Hsp70 expression by RNA interference (RNAi) resulted in increased apoptosis of cells infected with a Vpr-positive, but not Vpr-defective, HIV-1. Replication of the Vpr-positive HIV-1 was also increased when Hsp70 expression was diminished. Vpr and Hsp70 coimmunoprecipitated from HIV-infected cells. Together, these results identify Hsp70 as a novel anti-HIV innate immunity factor that targets HIV-1 Vpr.
