S-phase checkpoint pathways stimulate the mobility of the retrovirus-like transposon Ty1.
Article in Molecular and cellular biology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 papers.
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
The mobility of the Ty1 retrotransposon in the yeast Saccharomyces cerevisiae is restricted by a large collection of proteins that preserve the integrity of the genome during replication. Several of these repressors of Ty1 transposition (Rtt)/genome caretakers are orthologs of mammalian retroviral restriction factors. In rtt/genome caretaker mutants, levels of Ty1 cDNA and mobility are increased; however, the mechanisms underlying Ty1 hypermobility in most rtt mutants are poorly characterized. Here, we show that either or both of two S-phase checkpoint pathways, the replication stress pathway and the DNA damage pathway, partially or strongly stimulate Ty1 mobility in 19 rtt/genome caretaker mutants. In contrast, neither checkpoint pathway is required for Ty1 hypermobility in two rtt mutants that are competent for genome maintenance. In rtt101delta mutants, hypermobility is stimulated through the DNA damage pathway components Rad9, Rad24, Mec1, Rad53, and Dun1 but not Chk1. We provide evidence that Ty1 cDNA is not the direct target of the DNA damage pathway in rtt101delta mutants; instead, levels of Ty1 integrase and reverse transcriptase proteins, as well as reverse transcriptase activity, are significantly elevated. We propose that DNA lesions created in the absence of Rtt/genome caretakers trigger S-phase checkpoint pathways to stimulate Ty1 reverse transcriptase activity.
