Identification of a novel TOP2B::AFF2 fusion gene in B-cell acute lymphoblastic leukemia.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Genetic alterations play a pivotal role in leukemic clonal transformation, significantly influencing disease pathogenesis and clinical outcomes. Here, we report a novel fusion gene and investigate its pathogenic role in acute lymphoblastic leukemia (ALL). We engineer a transposon transfection system expressing the TOP2B::AFF2 transcript and introduce it into Ba/F3 cells. Functional studies, including proliferation, cell cycle, and apoptosis assays, were conducted to assess the fusion gene's impact. In vitro assays reveal that the TOP2B::AFF2 fusion significantly enhances Ba/F3 cell proliferation and G1/S phase transition while suppressing differentiation and apoptosis. This study identifies TOP2B::AFF2 as a potential oncogenic driver. However, further validation through in vivo studies are warranted to fully elucidate the fusion gene's role in leukemogenesis.
