Helicobacter pylori activates DOPEY1 to promote p53 degradation through the USP7/TRIP12 axis in gastric tumorigenesis.
Article in Oncogene, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
DOP1 leucine zipper-like protein A (DOPEY1), a member of the DOPEY family, is mainly localized in the Golgi apparatus, endosomes, and cytoplasmic compartments within cells. The involvement of DOPEY1 in H. pylori infection-induced carcinogenesis has remained unresolved. Here, we report that DOPEY1 is upregulated in GC tissues compared to adjacent normal tissues, correlating with poor prognosis. Mechanistically, H. pylori infection increases DOPEY1 expression and promotes p53 degradation through a CagA-dependent pathway. Using the String database and liquid chromatography-mass spectrometry, we identified DOPEY1-interacting proteins, confirming through co-immunoprecipitation that DOPEY1 interacts with USP7 and TRIP12. H. pylori infection enhances the expression of DOPEY1, USP7, and TRIP12, leading to p53 degradation, which is reversed by DOPEY1 silencing. Moreover, USP7 overexpression rescues p53 degradation in DOPEY1-silenced cells. Functionally, DOPEY1 knockdown reduces GC cell proliferation and suppresses tumor growth in mouse models. Immunohistochemistry analysis further reveals a link between DOPEY1, USP7, and TRIP12 expression, H. pylori infection, and GC progression. These findings demonstrate that H. pylori-induced upregulation of DOPEY1 drives p53 degradation via the USP7/TRIP12 axis, contributing to gastric tumorigenesis, and highlight DOPEY1 as a potential therapeutic target for H. pylori-associated GC.
