A Thermodynamic Perspective on Potential G-Quadruplex Structures as Silencer Elements in the MYC Promoter.
Article in Chemistry (Weinheim an der Bergstrasse, Germany), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Multiple G-tracts within the promoter region of the c-myc oncogene may fold into various G-quadruplexes with the recruitment of different tracts and guanosine residues for the G-core assembly. Thermodynamic profiles for the folding of wild-type and representative truncated as well as mutated sequences were extracted by comprehensive DSC experiments. The unique G-quadruplex involving consecutive G-tracts II-V with formation of two one-nucleotide and one central two-nucleotide propeller loop, previously proposed to be the biologically most relevant species, was found to be the most stable fold in terms of its Gibbs free energy of formation at ambient temperatures. Its stability derives from its short propeller loops but also from the favorable type of loop residues. Whereas quadruplex folds with long propeller loops are significantly disfavored, a snap-back loop structure formed by incorporating a 3'-terminal guanosine into the empty position of a tetrad seems highly competitive based on its thermodynamic stability. However, its destabilization by extending the 3'-terminus questions the significance of such a species under in vivo conditions.
