The correction of ETV6/RUNX1 translocation in acute lymphocytic leukemia cells: a new gene targeting system by homologous recombination mechanism.
Article in Journal of applied genetics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Regarding the uncertainty of the exact cause of the acute lymphocytic leukemia (ALL) caused by ETV6-RUNX1t(12;21) translocation, correcting genes of the ETV6 and RUNX1 in ETV6/RUNX1 fusion gene simultaneously on chromosome 12 may be effective in reducing leukemia malignancy. Thus, we designed an homologous recombination (HR) plasmid to target of the ETV6/RUNX1 fusion gene in the REH cell line containing the ETV6-RUNX1t(12;21) translocation. Cells were cultured and transfected by HR plasmid. The presence of the replacement cassette at specific location in the ETV6/RUNX1 fusion gene was verified by PCR and sequencing method. A quantitative gene expression assay was performed to evaluate changes in expression of ETV6, RUNX1, and ETV6/RUNX1 genes following editing. The cell viability was measured by trypan blue staining. The expression of the ETV6 gene was significantly increased in modified cells than unmodified cells by 10.9-fold. In contrast, the expression of the ETV6-RUNX1 fusion gene was significantly decreased in the modified cells compared with unmodified cells by 0.26-fold. The expression of the RUNX1 gene had no significant difference between modified and unmodified cells. The survival rate of edited cells was significantly decreased than unedited cells (p = 013). We designed a gene targeting system based on HR method to correct genes of ETV6 and RUNX1 simultaneously in ETV6/RUNX1 fusion gene on chromosome 12 containing ETV6-RUNX1t(12;21) translocation. The modification of this translocation may lead to reducing effects of the fusion gene's damaging and the dosage compensation related to ETV6 and RUNX1 genes and subsequently reduce the effects of leukemia. This targeting system may open a window for treating leukemia as ex vivo.
