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

The breast- and ovarian-specific tumor suppressor, BRCA1, has been implicated to function in many nuclear processes, including DNA damage repair, recombination, transcription, ubiquitination, cell cycle checkpoint enforcement, and centrosome regulation. Utilizing a previously described interaction between BRCA1 and RNA helicase A (RHA), we have developed a dominant-negative approach to block BRCA1 function in human breast epithelial cells. Overexpression of a truncated RHA peptide that can bind to the BRCA1 carboxy-terminus prevents normal BRCA1 function, such as BRCA1 association with nuclear foci following DNA damage. Overexpression of this dominant-negative protein induces pleomorphic nuclei, aberrant mitoses with extra centrosomes, and tetraploidy. This model system allows us to observe changes to mammary epithelial cells that occur acutely following loss of BRCA1 function. Furthermore, inhibition of BRCA1 via overexpressing the RHA fragment coincides with a reduction in PARP-1 protein expression, suggesting a possible mechanism for BRCA1 in the maintenance of genomic integrity.
