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

Zinc finger nucleases (ZFNs) have become powerful tools to deliver a targeted double-strand break at a pre-determined chromosomal locus in order to insert an exogenous transgene by homology-directed repair. ZFN-mediated gene targeting was used to generate both single-allele chemokine (C-C motif) receptor 5 (CCR5)-modified human induced pluripotent stem cells (hiPSCs) and biallele CCR5-modified hiPSCs from human lung fibroblasts (IMR90 cells) and human primary cord blood mononuclear cells (CBMNCs) by site-specific insertion of stem cell transcription factor genes flanked by LoxP sites into the endogenous CCR5 locus. The Oct4 and Sox2 reprogramming factors, in combination with valproic acid, induced reprogramming of human lung fibroblasts to form CCR5-modified hiPSCs, while 5 factors, Oct4/Sox2/Klf4/Lin28/Nanog, induced reprogramming of CBMNCs. Subsequent Cre recombinase treatment of the CCR5-modified IMR90 hiPSCs resulted in the removal of the Oct4 and Sox2 transgenes. Further genetic engineering of the single-allele CCR5-modified IMR90 hiPSCs was achieved by site-specific addition of the large CFTR transcription unit to the remaining CCR5 wild-type allele, using CCR5-specific ZFNs and a donor construct containing tdTomato and CFTR transgenes flanked by CCR5 homology arms. CFTR was expressed efficiently from the endogenous CCR5 locus of the CCR5-modified tdTomato/CFTR hiPSCs. These results suggest that it might be feasible to use ZFN-evoked strategies to (1) generate precisely targeted genetically well-defined patient-specific hiPSCs, and (2) then to reshape their function by targeted addition and expression of therapeutic genes from the CCR5 chromosomal locus for autologous cell-based transgene-correction therapy to treat various recessive monogenic human diseases in the future.
