USP22 regulates APL differentiation via PML-RARα stabilization and IFN repression.
Article in Cell death discovery, 2024. 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
Ubiquitin-specific peptidase 22 (USP22) is a deubiquitinating enzyme (DUB) that underlies tumorigenicity, proliferation, cell death and differentiation through deubiquitination of histone and non-histone targets. Ubiquitination determines stability, localization and functions of cell fate proteins and controls cell-protective signaling pathways to surveil cell cycle progression. In a variety of carcinomas, lymphomas and leukemias, ubiquitination regulates the tumor-suppressive functions of the promyelocytic leukemia protein (PML), but PML-specific DUBs, DUB-controlled PML ubiquitin sites and the functional consequences of PML (de)ubiquitination remain unclear. Here, we identify USP22 as regulator of PML and the oncogenic acute promyelocytic leukemia (APL) fusion PML-RARα protein stability and identify a destabilizing role of PML residue K394. Additionally, loss of USP22 upregulates interferon (IFN) and IFN-stimulated gene (ISG) expression in APL and induces PML-RARα stabilization and a potentiation of the cell-autonomous sensitivity towards all-trans retinoic acid (ATRA)-mediated differentiation. Our findings imply USP22-dependent surveillance of PML-RARα stability and IFN signaling as important regulator of APL pathogenesis, with implications for viral mimicry, differentiation and cell fate regulation in other leukemia subtypes.
