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

Cdc25B phosphatases function as key players in G2/M cell cycle progression by activating the CDK1-cyclinB1 complexes. They also have an essential role in recovery from the G2/M checkpoint activated in response to DNA damage. Overexpression of Cdc25B results in bypass of the G2/M checkpoint and illegitimate entry into mitosis, and also causes replicative stress, leading to genomic instability. Thus, fine-tuning of Cdc25B expression level is critical for correct cell cycle progression and G2 checkpoint recovery. However, the transcriptional regulation of Cdc25B remains largely unknown. Earlier studies have shown that the tumor suppressor p53 overexpression transcriptionally represses Cdc25B; however, the molecular mechanism of this repression has not yet been elucidated, although it was suggested to occur through the induction of p21. Here we show that Cdc25B is downregulated by the basal level of p53 in multiple cell types. This downregulation also occurs in p21-/- cell lines, indicating that p21 is not required for p53-mediated regulation of Cdc25B. Deletion and mutation analyses of the Cdc25B promoter revealed that downregulation by p53 is dependent on the presence of functional Sp1/Sp3 and NF-Y binding sites. Furthermore, chromatin immunoprecipitation analyses show that p53 binds to the Cdc25B promoter and mediates transcriptional attenuation through the Sp1 and NF-Y transcription factors. Our results suggest that the inability to downregulate Cdc25B after loss of p53 might contribute to tumorigenesis.
