DNA-Regulated Multi-Protein Complement Control.
Article in Journal of the American Chemical Society, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In nature, the interactions between proteins and their complements/substrates can dictate complex functions. Herein, we explore how DNA on nucleic acid modified proteins can be used as scaffolds to deliberately control interactions with a peptide complement (by adjusting length, sequence, and rigidity). As model systems, split GFPs were covalently connected through DNA scaffolds (36-58 bp). Increasing the length or decreasing the rigidity of the DNA scaffold (through removal of the duplex) increases the extent of intramolecular protein binding (up to 7.5-fold) between these GFP fragments. Independent and dynamic control over functional outputs can also be regulated by DNA hybridization; a multi-protein (split CFP and YFP) architecture was synthesized and characterized by fluorescence. This ternary construct shows that DNA displacement strands in different stoichiometric ratios can be used deliberately to regulate competitive binding between two unique sets of proteins. These studies establish a foundation for creating new classes of biological machinery based upon the concept of DNA-regulated multi-protein complement control.
