ATR Kinase Activity Limits Mutagenesis and Promotes the Clonogenic Survival of Quiescent Human Keratinocytes Exposed to UVB Radiation.
Article in Photochemistry and photobiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The ATR protein kinase has well-described roles in maintaining genomic integrity during the DNA synthesis phase of the cell cycle. However, ATR function in cells that are not actively replicating DNA remains largely unexplored. Using HaCaT and telomerase-immortalized human keratinocytes maintained in a confluent, nonreplicating state in vitro, ATR was found to be robustly activated in response to UVB radiation in a manner dependent on the nucleotide excision repair factor and DNA translocase XPB. Inhibition of ATR kinase activity under these conditions negatively impacted acute cell survival and cytotoxicity and severely inhibited the ability of UVB-irradiated HaCaT keratinocytes to proliferate upon stimulation with growth factors. Furthermore, ATR kinase inhibition in quiescent HaCaT keratinocytes potentiated UVB mutagenesis at the hypoxanthine phosphoribosyltransferase locus. Though ATR inhibition did not impact the rate of removal of cyclobutane pyrimidine dimers from genomic DNA, elevated levels of PCNA mono-ubiquitination and chromatin-associated PCNA and RPA indicate that excision gap-filling synthesis was altered in the absence of ATR signaling. These results indicate that the ATR kinase plays important roles in preventing mutagenesis and in promoting the proliferative potential of quiescent keratinocytes exposed to UVB radiation.
