A role for PCNA2 in translesion synthesis by Arabidopsis thaliana DNA polymerase eta.

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
Eukaryotic DNA polymerase eta (Poleta) confers ultraviolet (UV) resistance by catalyzing translesion synthesis (TLS) past UV photoproducts. Poleta has been studied extensively in budding yeast and mammalian cells, where its interaction with monoubiquitylated proliferating cell nuclear antigen (PCNA) is necessary for its biological activity. Recently, in collaboration with other investigators, our laboratory demonstrated that Arabidopsis thaliana Poleta is required for UV resistance in plants. Furthermore, the purified enzyme can perform TLS opposite a cyclobutane pyrimidine dimer and interacts with PCNA. Intriguingly, the biological activity of Poleta in a heterologous yeast assay depends on co-expression with Arabidopsis PCNA2 and Poleta sequences implicated in binding PCNA or ubiquitin. We suggest that interaction of Arabidopsis Poleta with ubiquitylated PCNA2 is required for TLS past UV photoproducts by Poleta.
