NOTCH1 signaling is dysregulated by loss of the deubiquitinase USP28 with del(11q), uncovering USP28 inhibition as novel therapeutic target in CLL.
Article in Leukemia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Aberrant active NOTCH1 signaling is a key pathogenic factor in chronic lymphocytic leukemia (CLL), detectable in half of patients and associated with disease progression. While some cases of active NOTCH1 signaling can be explained by mutations in NOTCH1 or its regulators, like FBXW7, alternative mechanisms remain elusive. Here, we identified the deubiquitinase USP28 as regulator of NOTCH1 signaling in CLL. Notably, USP28 is located within the frequently deleted chr11q23 region and is deleted in 90% of del(11q) patients, resulting in its decreased expression. USP28 interacts with the NOTCH1 intracellular domain (NICD) independently of FBXW7 and the NICD-PEST domain, stabilizing NICD and enhancing NOTCH1 signaling.
