Regulation of PDGFR-β gene expression by targeting the G-vacancy bearing G-quadruplex in promoter.
Article in Nucleic acids research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
G-quadruplex is an essential element in gene transcription that serves as a promising drug target. Guanine-vacancy-bearing G-quadruplex (GVBQ) is a newly identified G-quadruplex that has distinct structural features from the canonical G-quadruplex. Potential GVBQ-forming motifs are widely distributed in gene promoter regions. However, whether GVBQ can form in genomic DNA and be an effective target for manipulating gene expression is unknown. Using photo-crosslinking, dimethyl sulfate footprinting, exonuclease digestion and in vitro transcription, we demonstrated the formation of a GVBQ in the G-rich nuclease hypersensitivity element within the human PDGFR-β gene promoter region in both single-stranded and double-stranded DNA. The formation of GVBQ in dsDNA could be induced by negative supercoiling created by downstream transcription. We also found that the PDGFR-β GVBQ was specifically recognized and stabilized by a new synthetic porphyrin guanine conjugate (mPG). Targeting the PDGFR-β GVBQ in human cancer cells using the mPG could specifically alter PDGFR-β gene expression. Our work illustrates that targeting GVBQ with mPG in human cells can regulate the expression level of a specific gene, thus indicating a novel strategy for drug development.
