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 Gag protein is the major structural determinant of retrovirus assembly. Although a number of cellular factors have been reported to facilitate retrovirus release, little is known about the cellular machinery that directs Gag to the site of virus assembly. Here, we report roles for the Golgi-localized gamma-ear containing Arf-binding (GGA) and ADP ribosylation factor (Arf) proteins in retrovirus particle assembly and release. Whereas siRNA-mediated depletion of GGA2 and GGA3 led to a significant increase in particle release in a late domain-dependent manner, GGA overexpression severely reduced retrovirus particle production by impairing Gag trafficking to the membrane. GGA overexpression inhibited retroviral assembly and release by disrupting Arf protein activity. Furthermore, disruption of endogenous Arf activity inhibited particle production by decreasing Gag-membrane binding. These findings identify the GGA proteins as modulators of HIV-1 release and the Arf proteins as critical cellular cofactors in retroviral Gag trafficking to the plasma membrane.
