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

Guanine-rich nucleic acids can fold into G-quadruplexes, secondary structures implicated in important regulatory functions at the genomic level in humans, prokaryotes and viruses. The remarkably high guanine content of the Herpes Simplex Virus-1 (HSV-1) genome prompted us to investigate both the presence of G-quadruplex forming sequences in the viral genome and the possibility to target them with G-quadruplex ligands to obtain anti-HSV-1 effects with a novel mechanism of action. Using biophysical, molecular biology and antiviral assays, we showed that the HSV-1 genome displays multiple clusters of repeated sequences that form very stable G-quadruplexes. These sequences are mainly located in the inverted repeats of the HSV-1 genome. Treatment of HSV-1 infected cells with the G-quadruplex ligand BRACO-19 induced inhibition of virus production. BRACO-19 was able to inhibit Taq polymerase processing at G-quadruplex forming sequences in the HSV-1 genome, and decreased intracellular viral DNA in infected cells. The last step targeted by BRACO-19 was viral DNA replication, while no effect on virus entry in the cells was observed. This work, presents the first evidence of extended G-quadruplex sites in key regions of the HSV-1 genome, indicates the possibility to block viral DNA replication by G-quadruplex-ligand and therefore provides a proof of concept for the use of G-quadruplex ligands as new anti-herpetic therapeutic options.
