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

Highly compacted DNA nanoparticles (DNPs) composed of polyethylene glycol linked to a 30-mer of poly-l-lysine via a single cysteine residue (CK(30)PEG) have previously been shown to provide efficient gene delivery to the brain, eyes and lungs. In this study, we used a combination of flow cytometry, high-resolution live-cell confocal microscopy, and multiple particle tracking (MPT) to investigate the intracellular trafficking of highly compacted CK(30)PEG DNPs made using two different molecular weights of PEG, CK(30)PEG(10k) and CK(30)PEG(5k). We found that PEG MW did not have a major effect on particle morphology nor nanoparticle intracellular transport. CK(30)PEG(10k) and CK(30)PEG(5k) DNPs both entered human bronchial epithelial (BEAS-2B) cells via a caveolae-mediated pathway, bypassing degradative endolysosomal trafficking. Both nanoparticle formulations were found to rapidly accumulate in the perinuclear region of cells within 2h, 37±19% and 47±8% for CK(30)PEG(10k) and CK(30)PEG(5k), respectively. CK(30)PEG(10k) and CK(30)PEG(5k) DNPs moved within live cells at average velocities of 0.09±0.04μm/s and 0.11±0.04μm/s, respectively, in good agreement with reported values for caveolae. These findings show that highly compacted DNPs employ highly regulated trafficking mechanisms similar to biological pathogens to target specific intracellular compartments.
