1 · What the graph read from it

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.

2 · The registry

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

Nanoscale bilayer mimetics such as protein or polymer-based nanodiscs are versatile tools to study the physical chemistry of lipid bilayers or the structures and functions of membrane proteins. Here, we introduce DNA-lipid nanodiscs (DLNs) in which the interface between hydrophobic lipids and the charged DNA is mediated through amphiphilic poly(ethylene)glycol (PEG). For this, we modified oligonucleotides with PEG and hybridized them to a single-stranded ring to form functionalized minicircles with a well-defined diameter. The center of these minicircles can be filled with a lipid bilayer through addition of detergent-solubilized lipids followed by detergent removal. Simulations reveal that the methylene groups in PEG form dynamic interactions with the acyl chains of lipids, effectively shielding the hydrophobic mismatch. As proof of concept toward incorporation of complex membrane proteins, we inserted the biotinylated transmembrane domain of synaptobrevin into these nanodiscs and bound them to streptavidin-modified quantum dots as a marker for successful incorporation. We envision these atomically precise, modular DNA scaffolds to be widely applicable in future studies of membrane proteins and nanoscale lipid membranes.
