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

Triplex-forming peptide nucleic acids (PNAs) are powerful gene therapy agents that can enhance recombination of short donor DNAs with genomic DNA, leading to targeted and specific correction of disease-causing genetic mutations. Therapeutic use of PNAs is severely limited, however, by challenges in intracellular delivery, particularly in clinically relevant targets such as hematopoietic stem and progenitor cells. Here, we demonstrate efficient and nontoxic PNA-mediated recombination in human CD34(+) cells using poly(lactic-co-glycolic acid) (PLGA) nanoparticles for intracellular oligonucleotide delivery. Treatment of progenitor cells with nanoparticles loaded with PNAs and DNAs targeting the β-globin locus led to levels of site-specific modification in the range of 0.5-1% in a single treatment, without detectable loss in cell viability, resulting in a 60-fold increase in modified and viable cells as compared to nucleofection. As well, the differentiation capacity of the progenitor cells treated with nanoparticles did not change relative to untreated progenitor cells, indicating that nanoparticles are safe and minimally disruptive delivery vectors for PNAs and DNAs to mediate gene modification in human primary cells. This is the first demonstration of the use of biodegradable nanoparticles to deliver genome-editing agents to human primary cells, and provides a strong rationale for systemic delivery of complex nucleic acid mixtures designed for gene correction.
