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 ZMYM2-FGFR1 (formerly known as ZNF198-FGFR1) fusion kinase induces stem cell leukemia-lymphoma syndrome (SCLL), a hematologic malignancy characterized by rapid transformation to acute myeloid leukemia and T-lymphoblastic lymphoma. In the present study, we demonstrate frequent, constitutive activation of Notch1 and its downstream target genes in T-cell lymphomas that arose in a murine model of ZMYM2-FGFR1 SCLL. Notch up-regulation was also demonstrated in human SCLL- and FGFR1OP2-FGFR1-expressing KG-1 cells. To study the role of Notch in T-cell lymphomagenesis, we developed a highly tumorigenic cell line from ZMYM2-FGFR1-expressing cells. Pharmacologic inhibition of Notch signaling in these cells using γ-secretase inhibitors significantly delayed leukemogenesis in vivo. shRNA targeting of Notch1, as well as c-promoter-binding factor 1 (CBF1) and mastermind-like 1 (MAML1), 2 essential cofactors involved in transcriptional activation of Notch target genes, also significantly delayed or inhibited tumorigenesis in vivo. Mutation analysis demonstrated that 5' promoter deletions and alternative promoter usage were responsible for constitutive activation of Notch1 in all T-cell lymphomas. These data demonstrate the importance of Notch signaling in the etiology of SCLL, and suggest that targeting this pathway could provide a novel strategy for molecular therapies to treat SCLL patients.
