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 role of the Notch signaling pathway in tumor development is complex, with Notch1 functioning either as an oncogene or as a tumor suppressor in a context-dependent manner. To further define the role of Notch1 in tumor development, we systematically surveyed for tumor suppressor activity of Notch1 in vivo. We combined the previously described Notch1 intramembrane proteolysis-Cre (Nip1::Cre) allele with a floxed Notch1 allele to create a mouse model for sporadic, low-frequency loss of Notch1 heterozygosity. Through this approach, we determined the cell types most affected by Notch1 loss. We report that the loss of Notch1 caused widespread vascular tumors and organism lethality secondary to massive hemorrhage. These findings reflected a cell-autonomous role for Notch1 in suppressing neoplasia in the vascular system and provide a model by which to explore the mechanism of neoplastic transformation of endothelial cells. Importantly, these results raise concerns regarding the safety of chronic application of drugs targeting the Notch pathway, specifically those targeting Notch1, because of mechanism-based toxicity in the endothelium. Our strategy also can be broadly applied to induce sporadic in vivo loss of heterozygosity of any conditional alleles in progenitors that experience Notch1 activation.
