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

Genetic instability caused by mutations in the p53 gene is generally thought to be due to a loss of the DNA damage response that controls checkpoint functions and apoptosis. Cells with mutant p53 exhibit high levels of homologous recombination (HR). This could be an indirect consequence of the loss of DNA damage response or p53 could have a direct role in HR. Here, we report that p53-/- mouse embryonic fibroblasts (MEFs) exhibit higher levels of the RAD51 protein and increased level of spontaneous RAD51 foci Agents that stall replication forks, for example, hydroxyurea (HU), potently induce HR repair and RAD51 foci. To test if the increase in RAD51 foci in p53-/- MEFs was due to an increased level of damage during replication, we measured the formation of DNA double-strand breaks (DSBs) in p53+/+ and p53-/- MEFs following treatments with HU. We found that HU induced DSBs only in p53-/- MEFs, indicating that p53 is involved in a pathway to protect stalled replication forks from being collapsed into a substrate for HR. Also, p53 is upregulated in response to agents that inhibit DNA replication, which supports our hypothesis. Finally, we observed that the DSBs produced in p53-/- MEFs did not result in a permanent arrest of replication and that they were repaired. Altogether, we suggest that the effect of p53 on HR and RAD51 levels and foci can be explained by the idea that p53 suppresses formation of recombinogenic lesions.
