IQGAP1 Negatively Regulates HIV-1 Gag Trafficking and Virion Production.
Article in Cell reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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.
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
IQGAP1 is a master regulator of many cellular processes, including intracellular vesicle trafficking and endocytosis. We show that depletion of IQGAP1 in a variety of cell types increases the release of HIV-1 infectious virions and that overexpression diminishes virion production, with neither affecting the early stages of infection. IQGAP1 negatively regulates the steady-state levels of HIV-1 Gag at the plasma membrane, the site of assembly. We establish that IQGAP1 interacts with both the nucleocapsid and p6 domains of Gag, and interaction with either domain is sufficient for its regulatory function. Finally, we demonstrate that IQGAP1 regulation is independent of HIV-1 Gag "late-domains" sequences required by the virus to recruit the cellular ESCRT machinery. Thus, we provide evidence that IQGAP1 is a negative regulatory factor inhibiting efficient budding of HIV-1 by reducing Gag accumulation at the plasma membrane.
