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

Breast-cancer-associated gene 1 (BRCA1) is highly expressed in thymus and spleen. In this paper, we have studied lymphocyte development and tumorigenesis in mice carrying mutations in Brca1 and p53. We show that the deletion of Brca1 exon 11 (Brca1-delta11), which disrupts the full-length isoform, but not the short isoform of Brca1, does not interfere with lymphocyte development. This is true irrespective of p53 status, that is, whether it is wild type, heterozygous or homozygous for a null mutation. These data suggest that the expression of Brca1 short isoform alone is enough to maintain normal development of lymphocytes. However, it cannot suppress tumorigenesis as about 30% of Brca1(delta11/delta11)p53(+/-) mice develop thymic lymphoma between 3 and 7 months of age. We demonstrate that p53 plays an essential role in Brca1-associated lymphoma, as all the tumors from Brca1(delta11/delta11)p53(+/-) mice exhibit LOH of p53 and Brca1(delta11/delta11)p53(-/-) mice exhibited accelerated tumorigenesis. We further demonstrate that the Brca1-delta11 deficiency does not affect thymocyte proliferation; however, it increases genetic instability and triggers gamma-irradiation-induced apoptosis. The loss of p53 attenuates apoptosis and allows accumulation of further mutations in Brca1-delta11 thymocytes, eventually leading to thymic lymphoma formation.
