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

The clustered regulatory interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) system is an efficient genome-editing tool that holds potential for gene therapy. Here, we report an application of this system for gene repair in hemophilia B (HB) using induced pluripotent stem cells (iPSCs). We prepared targeting plasmids with homology arms containing corrected sequences to repair an in-frame deletion in exon 2 of the factor IX (F9) gene and transfected patient-derived iPSCs with the Cas9 nuclease and a guide RNA expression vector. To validate the expression of corrected F9, we attempted to induce the differentiation of iPSCs toward hepatocyte-like cells (HLCs) in vitro. We successfully repaired a disease-causing mutation in HB in patient-derived iPSCs. The transcription product of corrected F9 was confirmed in HLCs differentiated from gene-corrected iPSCs. Although further research should be undertaken to obtain completely functional hepatocytes with secretion of coagulation factor IX, our study provides a proof-of-principle for HB gene therapy using the CRISPR/Cas9 system.
