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

Human replication protein A (RPA) becomes phosphorylated on the RPA2 subunit by cyclin B-Cdc2 during mitosis, although the functional role of this modification is unclear. We find that this modification stimulates RPA2 to become hyperphosphorylated in response to mitotic DNA damage caused by bleomycin treatment. Cells in which endogenous RPA2 was replaced by a mutant subunit lacking both Cdc2 sites had a significant defect in mitotic release into a 2N G(1) phase after exposure to bleomycin. An increased percentage of these mutant cells also was positive initially for cyclin B expression and BubR1 chromatin staining, indicative of an extended spindle assembly checkpoint. The mutant cells that experienced mitotic DNA damage also underwent apoptosis at higher levels than cells expressing the WT subunit. Even so, we did not find the mutation had any dramatic effects on the level of DNA repair in mitosis. Cells lacking ATM (a checkpoint factor and RPA2 kinase) also were severely defective in mitotic exit and were unable to support RPA hyperphosphorylation after mitotic DNA damage. Although checkpoint 1 effector kinase (Chk1) had a more complex role, inhibition of Chk1 activity with UCN-01 also reduced mitotic exit. Chk1 activation and mitotic RPA hyperphosphorylation were found to be independent events. Our results demonstrate that mitotic RPA hyperphosphorylation facilitates release of cells from a damaged mitosis into a 2N G(1) phase, thereby increasing cell viability.
