Background/Aims:
Cholangiocarcinoma (CCA) is a primary malignant neoplasm with an extremely poor prognosis. While combined chemoradiotherapy has been demonstrated to delay CCA progression to a certain extent, the absence of specific molecular biomarkers or targets significantly hinders the diagnosis and treatment of CCA.
Methods:
Through cross-analysis of proteomics and ADMA modificationomics, we identified DDX1 overexpressed in CCA with elevated R602-ADMA modifications. HPLC-MS/MS identified PRMT1 as the methyltransferase and USP10 as the deubiquitinating enzyme for DDX1. Immunofluorescence and nuclear-cytoplasmic partitioning experiments confirmed DDX1’s nuclear localization. GO and KEGG analyses clarify the biological functions of DDX1 in response to hypoxia. RNA-seq transcriptomics analyzed key pathways influenced by DDX1. A hydrodynamic in situ CCA mouse model was established to validate the chemopreventive effects of the PRMT1-specific inhibitor GSK715 on CCA development.
Results:
DDX1 promotes CCA progression both in vivo and in vitro and can be inhibited by GSK715. Mechanistically, PRMT1 mediates ADMA modification at position R602 of DDX1. This modification promotes DDX1 nuclear localization by recruiting USP10 to deubiquitinate DDX1, while simultaneously inhibiting PRMT1 degradation. DDX1 promotes the transcription of PRMT1 and USP10 by binding to the mRNA 3’UTR region, establishing a positive feedback regulatory pathway. This mechanism promotes the occurrence and development of CCA and can serve as a target for the inhibitor GSK715 to suppress CCA progression.
Conclusions
Our study identified DDX1-R602-ADMA modification as a novel ADMA modification in CCA. It further confirmed its pivotal role in CCA progression. Targeting the USP10-PRMT1-DDX1 axis may represent a significant therapeutic approach for CCA.

Hyperuricemia(HUA)and gout became typical metabolic disorders characterized by multiple pathogenic factors.Their incidence increased annually,affecting younger populations.Given that uric acid(UA)and inflammation were the primary disease mechanisms,the search for effective and low-side-effect UA-lowering and anti-inflammatory drugs became a pressing scientific priority.Traditional Chinese medi-cine(TCM)encompassed a rich array of theoretical and practical experience,along with a diverse range of chemical substances,making herbs or their components potential sources for therapeutic drugs.Despite the significant role that modern herbal medicines played in treating HUA and gout,the existing research literature remained fragmented,lacking comprehensive and systematic reviews.In this review,we focused on the regulation of UA and summarized the discovery of UA-lowering pharmacodynamic components or ingredients derived from herbs and formulas,as well as their multi-targeted mechanisms of action.Emphasizing this focus,we proposed that,compared to acute inflammation,low-grade inflammation may play a relatively"unnoticed"role in the disease process.In contrast to Western medicine,we discussed the risks and benefits of herbal medicines and their ingredients for treatment,drawing from theoretical insights and clinical practice.This review offered comprehensive perspectives on the research into anti-HUA and gout treatments using herbal medicines and their natural products.Additionally,it provided a forward-looking view on natural product discovery,the exploration of ther-apeutic strategies,and new drug research in this field.
