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

There are many sources of genetic diversity, ranging from programmed mutagenesis in antibody genes to random mutagenesis during species evolution or development of cancer. We propose that mutations in DNA sequence-specific transcription factors that target response elements (REs) in many genes can also provide for rapid and broad phenotypic diversity, if the mutations lead to altered binding affinities at individual REs. To test this concept, we examined the in vivo transactivation capacity of wild-type human and murine p53 and 25 partial function mutants. The p53s were expressed in yeast from a rheostatable promoter, and the transactivation capacities toward >15 promoter REs upstream of a reporter gene were measured. Surprisingly, there was wide variation in transactivation by the mutant p53s toward the various REs. This is the first study to address directly the impact of mutations in a sequence-specific transcription factor on transactivation from a wide array of REs. We propose a master gene hypothesis for phenotypic diversity where the master gene is a single transcriptional activator (or repressor) that regulates many genes through different REs. Mutations of the master gene can lead to a variety of simultaneous changes in both the selection of targets and the extent of transcriptional modulation at the individual targets, resulting in a vast number of potential phenotypes that can be created with minimal mutational changes without altering existing protein-protein interactions.
