G-quadruplex motifs in Neisseria gonorrhoeae as anti-gonococcal targets.
Article in Applied microbiology and biotechnology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Neisseria gonorrhoeae is an obligate human pathogen that causes gonorrhea and has shown a vast emergence of multidrug resistance in recent times. It is necessary to develop novel therapeutic strategies to combat this multidrug-resistant pathogen. The non-canonical stable secondary structures of nucleic acids, G-quadruplexes (GQs), are reported to regulate gene expressions in viruses, prokaryotes, and eukaryotes. Herein, we explored the whole genome of N. gonorrhoeae to mine evolutionary conserved GQ motifs. The Ng-GQs were highly enriched in the genes involved in various important biological and molecular processes of N. gonorrhoeae. Five of these GQ motifs were characterized using biophysical and biomolecular techniques. The GQ-specific ligand, BRACO-19, showed a high affinity towards these GQ motifs and stabilized them in both in vitro and in vivo conditions. The ligand showed potent anti-gonococcal activity and modulated the gene expression of the GQ-harboring genes. Strikingly, BRACO-19 also altered the biofilm formation in N. gonorrhoeae and its adhesion and invasion of the human cervical epithelial cells. In summary, the present study showed a significant role of GQ motifs in N. gonorrhoeae biology and put forward a step closer towards the search for therapeutic measures in combating the emerging antimicrobial resistance in the pathogen. KEY POINTS: •Neisseria gonorrhoeae genome is enriched in non-canonical nucleic acid structures-G-quadruplexes. •These G-quadruplexes might regulate bacterial growth, virulence, and pathogenesis. •G-quadruplex ligands inhibit biofilm formation, adhesion, and invasion of the gonococcus bacterium.
