p73 transcriptional activity increases upon cooperation between its spliced forms.
Article in Oncogene, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 p53 homologue p73 efficiently activates p53-responsive genes. The well documented over-expression of p73 spliced forms in a wide variety of tumor types promoted us to elucidate the mechanisms underlying p73-mediated transcription. Using the luciferase reporter gene driven by Mdm2-minimal promoter in p53 null cells, we demonstrate that the weak transcriptional activity mediated by p73alpha was increased by the mutant form p73beta292, which by itself is transcriptionally inactive. Similarly, cooperation between p73beta and an inactive form of p73alpha increased p73beta-mediated transcriptional activities. Conversely, p73beta elicited a silencing effect on a gain of function mutant, p53(281), which by itself mediated efficient transactivation of the MDR promoter. Neither anisomycin nor actinomycin D altered p73-mediated transcriptional activities, whereas sorbitol profoundly inhibited them through a rapid proteasome-dependent degradation of p73. Our observations point to plausible scenarios in which p73, through cooperation between p73 spliced forms and suppression of gain of function mutant p53 may elicit changes in the transcription of p53 target genes that play key roles in cell growth and death.
