Expression of an amino-terminal BRCA1 deletion mutant causes a dominant growth inhibition in MCF10A cells.
Article in Oncogene, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Expression of deletion mutants of the breast and ovarian cancer-specific tumor suppressor protein, BRCA1, in the mammary epithelial cell line MCF10A revealed a powerful growth suppressive effect by a mutant that has the amino-terminal 302 amino acids deleted (DeltaN-BRCA1). The growth suppression is associated with an increase in apoptosis and amplification in centrosome number. The growth inhibitory effect of DeltaN-BRCA1 was not observed in cervical epithelial HeLa cells, suggesting that the phenotypes of BRCA1 mutant proteins differ depending on the cell line being tested. An internal domain, including BRCA1 residues 303-1292, caused the suppression of MCF10A cell growth, and the amino terminus of BRCA1 autoinhibited the growth suppression. Single point mutations that disrupted the amino-terminal RING domain of BRCA1 caused significant suppression of growth in MCF10A cells. These results suggest that the proper function of the RING domain, likely to be ubiquitin ligase function, is important in regulating the growth of the mammary epithelial cell line and in autoregulating the powerful internal growth-inhibiting domain of the BRCA1 tumor suppressor.
