Modulating DNA by polyamides to regulate transcription factor PU.1-DNA binding interactions.
Article in Biochimie, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Hairpin polyamides are synthetic small molecules that bind DNA minor groove sequence-selectively and, in many sequences, induce widening of the minor groove and compression of the major groove. The structural distortion of DNA caused by polyamides has enhanced our understanding of the regulation of DNA-binding proteins via polyamides. Polyamides have DNA binding affinities that are comparable to those proteins, therefore, can potentially be used as therapeutic agents to treat diseases caused by aberrant gene expression. In fact, many diseases are characterized by over- or under-expressed genes. PU.1 is a transcription factor that regulates many immune system genes. Aberrant expression of PU.1 has been associated with the development of acute myeloid leukemia (AML). We have, therefore, designed and synthesized ten hairpin polyamides to investigate their capacity in controlling the PU.1-DNA interaction. Our results showed that nine of the polyamides disrupt PU.1-DNA binding and the inhibition capacity strongly correlates with binding affinity. One molecule, FH1024, was observed forming a FH1024-PU.1-DNA ternary complex instead of inhibiting PU.1-DNA binding. This is the first report of a small molecule that is potentially a weak agonist that recruits PU.1 to DNA. This finding sheds light on the design of polyamides that exhibit novel regulatory mechanisms on protein-DNA binding.
