A G-quadruplex motif in an envelope gene promoter regulates transcription and virion secretion in HBV genotype B.
Article in Nucleic acids research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 55 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
HBV genotypes differ in pathogenicity. In addition, genotype-specific differences in the regulation of transcription and virus replication exist in HBV, but the underlying mechanisms are unknown. Here, we show the presence of a G-quadruplex motif in the promoter of the preS2/S gene; this G-quadruplex is highly conserved only in HBV genotype B but not in other HBV genotypes. We demonstrate that this G-quadruplex motif forms a hybrid intramolecular G-quadruplex structure. Interestingly, mutations disrupting the G-quadruplex in HBV genotype B reduced the preS2/S promoter activity, leading to reduced hepatitis B surface antigen (HBsAg) levels. G-quadruplex ligands stabilized the G-quadruplex in genotype B and enhanced the preS2/S promoter activity. Furthermore, mutations disrupting the G-quadruplex in the full-length HBV genotype B constructs were associated with impaired virion secretion. In contrast to typical G-quadruplexes within promoters which are negative regulators of transcription the G-quadruplex in the preS2/S promoter of HBV represents an unconventional positive regulatory element. Our findings highlight (a) G-quadruplex mediated enhancement of transcription and virion secretion in HBV and (b) a yet unknown role for DNA secondary structures in complex genotype-specific regulatory mechanisms in virus genomes.
