Transactivation domain of p53 regulates DNA repair and integrity in human iPS cells.

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
The role of p53 transactivation domain (p53-TAD), a multifunctional and dynamic domain, on DNA repair and retaining DNA integrity in human induced pluripotent stem cells (hiPSCs) has never been studied. p53-TAD was knocked out in iPSCs using CRISPR/Cas9 and was confirmed by DNA sequencing. p53-TAD knockout (KO) cells were characterized by accelerated proliferation, decreased population doubling time, and unaltered Bcl-2, Bcl-2-binding component 3, insulin-like growth factor 1 receptor, and Bax and altered Mdm2, p21, and p53-induced death domain transcript expression. In p53-TAD KO cells, the p53-regulated DNA repair proteins xeroderma pigmentosum group A, DNA polymerase H, and DNA-binding protein 2 expression were found to be reduced compared with p53 wild-type cells. Exposure to a low dose of doxorubicin (Doxo) induced similar DNA damage and DNA damage response (DDR) as measured by RAD50 and MRE11 expression, checkpoint kinase 2 activation, and γH2A.X recruitment at DNA strand breaks in both cell groups, indicating that silence of p53-TAD does not affect the DDR mechanism upstream of p53. After removal of Doxo, p53 wild-type hiPSCs underwent DNA repair, corrected their damaged DNA, and restored DNA integrity. Conversely, p53-TAD KO hiPSCs did not undergo complete DNA repair and failed to restore DNA integrity. More importantly, continuous culture of p53-TAD KO hiPSCs underwent G
