Three assays show differences in binding of wild-type and mutant p53 to unique gene sequences.
Article in Technology in cancer research & treatment, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Cancer-associated mutations in the p53 gene often change amino acids in the protein's DNA binding domain. We used three different binding assays specifically gel shift, DNA binding scintillation proximity assay and a streptavidin magnetic bead assay to analyze the DNA binding of the tumor suppressor p53 from 4 human cell lines with different DNA sequences from the mdm2, p21 and cyclin G genes and a mutant form of the cyclin G sequence. Treatment of MCF-7 cells having wild-type p53 with hydrogen peroxide increased the binding of p53 to DNA as detected using all three assays, but to different extents. The p53 proteins from the thyroid cancer cell lines with different p53 mutations (ARO, WRO and NPA) have comparable binding reactions in the three assays, but show different specificities for the sequences. Here we show that multiple different binding assays allow us to generate a more complete picture of the function of DNA transcription factors in diseases such as cancer.
