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

DNA lesions arise from many endogenous and environmental agents, and such lesions can promote deleterious events leading to genomic instability and cell death. Base excision repair (BER) is the main DNA repair pathway responsible for repairing single strand breaks, base lesions and abasic sites in mammalian cells. During BER, DNA substrates and repair intermediates are channeled from one step to the next in a sequential fashion so that release of toxic repair intermediates is minimized. This includes handoff of the product of gap-filling DNA synthesis to the DNA ligation step. The conformational differences in DNA polymerase β (pol β) associated with incorrect or oxidized nucleotide (8-oxodGMP) insertion could impact channeling of the repair intermediate to the final step of BER, i.e., DNA ligation by DNA ligase I or the DNA Ligase III/XRCC1 complex. Thus, modified DNA ligase substrates produced by faulty pol β gap-filling could impair coordination between pol β and DNA ligase. Ligation failure is associated with 5'-AMP addition to the repair intermediate and accumulation of strand breaks that could be more toxic than the initial DNA lesions. Here, we provide an overview of the consequences of ligation failure in the last step of BER. We also discuss DNA-end processing mechanisms that could play roles in reversal of impaired BER.
