In this study, we searched for mTOR regulators and found that the splicing factor SRRM2 modulates the levels of S6K1 and S6K2, thereby activating the mTOR-S6K pathway. Interestingly, SRRM2 facilitates the expression of S6K2 by modulating alternative splicing, and enhances the stability of the S6K1 protein by regulating the E3 ubiquitin ligase WWP2. Moreover, SRRM2 is highly expressed in colorectal cancer (CRC) tissues and is associated with a poor prognosis. SRRM2 promotes CRC growth in vitro and in vivo.

The glucocorticoid receptor (GR), a ligand-activated transcription factor (TF), mediates their actions. Chromatin occupancy, chromatin-protein networks (chromatomes) and gene programmes of GR are regulated by SUMOylation, a post-translational modification with therapeutic implications in other hematomalignancies. To unravel the GR-SUMOylation crosstalk in B-ALL, we induced hypoSUMOylation in NALM6 B-ALL cells with a SUMOylation inhibitor (SUMOi, ML-792). Genome-wide profiling of GR and SUMO chromatin-binding and chromatin accessibility revealed that hypoSUMOylation augmented GR chromatin occupancy and altered chromatin openness. Association with transcriptome data indicated that the hypoSUMOylation-induced GR-binding sites predominantly repressed genes associated with cell cycle and DNA replication. Consistently, hypoSUMOylation potentiated glucocorticoid-induced cell cycle arrest and growth suppression. Moreover, our proteomic analyses revealed that the protein network of chromatin-bound GR is tightly intertwined with SUMO2/3 and that SUMOylation modulates the stability of the network. The chromatome contained several B-cell TFs with cognate binding motifs found on GR-adjacent chromatin sites, indicating their simultaneous occupancy on chromatin.

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.</p>","PeriodicalId":19524,"journal":{"name":"Oncogene","volume":" ","pages":""},"PeriodicalIF":6.9,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143408467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One circular RNA, circAFF2, was found to be significantly upregulated in AML patients. Functional studies showed that knockdown of circAFF2 could significantly inhibit the proliferation of AML cells and promote their apoptosis. Overexpression of circAFF2 can have opposite effects. In vivo experiments showed that transplantation of AML cells with circAFF2 knockdown slowed the proliferation and infiltration and prolonged the survival time of mice compared to controls.

We established that PRSS23 influences gastric cancer growth both in vitro and in vivo by modulating the eIF4E-c-Myc axis (eIF4E, p-eIF4E, 4EBP1, p-4EBP1, and c-Myc).
