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

Retroviral genome selection and virion assembly remain promising targets for novel therapeutic intervention. Recent studies have demonstrated that the Gag proteins of Rous sarcoma virus (RSV) and human immunodeficiency virus type-1 (HIV-1) undergo nuclear trafficking, colocalize with nascent genomic viral RNA (gRNA) at transcription sites, may interact with host transcription factors, and display biophysical properties characteristic of biomolecular condensates. In the present work, we utilized a controlled in vitro condensate assay and advanced imaging approaches to investigate the effects of interactions between RSV Gag condensates and viral and nonviral RNAs on condensate abundance and organization. We observed that the psi (Ψ) packaging signal and the dimerization initiation sequence (DIS) had stabilizing effects on RSV Gag condensates, while RNAs lacking these features promoted or antagonized condensation, depending on local protein concentration and condensate architecture. An RNA containing Ψ, DIS, and the dimerization linkage structure (DLS) that is capable of stable dimer formation was observed to act as a bridge between RSV Gag condensates. These observations suggest additional, condensate-related roles for Gag-Ψ binding, gRNA dimerization, and Gag dimerization/multimerization in gRNA selection and packaging, representing a significant step forward in our understanding of how these interactions collectively facilitate efficient genome packaging.
