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

HIV-1 infection triggers multiple cellular pathways that modulate viral replication and may promote latency. Central to this process is the reverse transcription of the viral RNA into DNA and its integration into host chromatin, both processes being regulated by the cell. Emerging evidence suggests that homologous recombination (HR) proteins, especially RAD51, may influence both pre- and post-integration stages. In this study, we show that HIV-1 induces the rapid formation of RAD51 nuclear foci in a BRCA1/2-dependent manner, with RAD51 loading onto viral DNA immediately during reverse transcription. Using ChIP, imaging, and biochemical assays, we demonstrate that this process enhances viral infectivity and reverse transcription efficiency. Our findings reveal a previously unidentified cellular response that recruits repair factors to viral DNA, regulating reverse transcription and influencing viral DNA fate. This work uncovers a previously unknown role for RAD51 in modulating early HIV-1 replication, providing insights into host-virus interactions and potential therapeutic strategies.
