Effects of chromosomal integration site upon p53 interactions with DNA consensus sequence homologies.
Article in Oncogene, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
In the present study, we report that, despite the presence of one perfect p53 consensus sequence homology (designated SCL CS) and four half-sites within the 3'-untranslated region of the stem cell leukemia (SCL) gene, the native endogenous gene is not regulated by p53. We employ a tet-repressible system to show that, under conditions in which the WAF1 mRNA steady-state level is upregulated fourfold by p53, the SCL mRNA level is not altered. In a previous report, we demonstrated that p53 interactions with the SCL CS can upregulate downstream reporter gene activity 43-fold in transient reporter assays. This disparity prompted us to explore the differences between p53 regulation of SCL CS activity in organized (chromosomally integrated) and disorganized (non-replicating episomal plasmid) chromatin. We show that p53 can increase (between 3-80-fold), decrease (between 5-33-fold) or have no effect upon transactivation of an SCL CS/reporter fusion gene depending upon chromosomal integration site. Most studies used to characterize p53 binding sites employ transient transfection assays. Our results suggest that characterization of consensus sequence homologies by assay of transiently transfected cells may be inaccurate.
