Autorepression of rfx1 gene expression: functional conservation from yeast to humans in response to DNA replication arrest.

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 yeast Saccharomyces cerevisiae Crt1 transcription repressor is an effector of the DNA damage and replication checkpoint pathway. Crt1 binds and represses genes encoding ribonucleotide reductase (RNR) and its own promoter, establishing a negative-feedback pathway. The role of Rfx1, the mammalian Crt1 homologue, remained uncertain. In this study we investigated the possibility that Rfx1 plays a similar function in animal cells. We show here that, like Crt1, Rfx1 binds and represses its own promoter. Furthermore, Rfx1 binding to its promoter is reduced upon induction of a DNA replication block by hydroxyurea, which led to a release of repression. Significantly, like Crt1, Rfx1 binds and represses the RNR-R2 gene. Upon blocking replication and UV treatment, expression of both Rfx1 and RNR-R2 is induced; however, unlike the results seen with the RNR-R2 gene, the derepression of the RFX1 gene is only partially blocked by inhibiting Chk1, the DNA checkpoint kinase. This report provides evidence for a common mechanism for Crt1 and Rfx1 expression and for the conservation of their mode of action in response to a DNA replication block. We suggest that Rfx1 plays a role in the DNA damage response by down-regulating a subset of genes whose expression is increased in response to replication blocking and UV-induced DNA damage.
