Activation of Aicda gene transcription by Pax5 in plasmacytoma cells.
Article in Immunologic research, 2013. 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
Activation-induced deaminase (AID) is an enzyme responsible for somatic hypermutation and immunoglobulin heavy chain class switch recombination. Because AID causes double-stranded breaks in DNA, its expression is highly regulated and is normally restricted to germinal-center B cells. Dysregulated AID expression can lead to cancer as a result of AID-mediated chromosomal translocations. Many transcription factors including paired box protein 5 (Pax5) have been implicated in regulating the expression of Aicda, the gene encoding AID. In this study, we demonstrate that exogenous expression of Pax5 in a murine plasmacytoma cell line, 558LμM, leads to robust activation of endogenous Aicda transcription. Pax5 is known to initiate transcription through both its N-terminal-paired DNA-binding domain and its C-terminal-activation domain. Through mutational analysis, we demonstrate that Pax5 regulates Aicda transcription through its C-terminal-activation domain. Together, our work describes a novel system that will be useful for determining how Pax5 regulates Aicda transcription.
