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

This study reports an unusual ploidy-specific response to replication stress presented by a defective minichromosome maintenance (MCM) helicase allele in yeast. The corresponding mouse allele, Mcm4(Chaos3), predisposes mice to mammary gland tumors. While mcm4(Chaos3) causes replication stress in both haploid and diploid yeast, only diploid mutants exhibit G2/M delay, severe genetic instability (GIN), and reduced viability. These different outcomes are associated with distinct repair pathways adopted in haploid and diploid mutants. Haploid mutants use the Rad6-dependent pathways that resume stalled forks, whereas the diploid mutants use the Rad52- and MRX-dependent pathways that repair double strand breaks. The repair pathway choice is irreversible and not regulated by the availability of repair enzymes. This ploidy effect is independent of mating type heterozygosity and not further enhanced by increasing ploidy. In summary, a defective MCM helicase causes GIN only in particular cell types. In response to replication stress, early events associated with ploidy dictate the repair pathway choice. This study uncovers a fundamental difference between haplophase and diplophase in the maintenance of genome integrity.
