Integrative proteogenomic characterization of Wilms tumor

Area of Science:

• Oncology
• Genomics
• Molecular Biology

Background:

• Wilms tumor (WT) is the most common pediatric renal malignancy.
• WT has a low mutational burden, complicating targeted therapy development.

Purpose of the Study:

• To comprehensively characterize the molecular landscape of Wilms tumor.
• To identify prognostic biomarkers and potential therapeutic targets for WT.

Main Methods:

• Integrative analysis of proteomic, phosphoproteomic, transcriptomic, and whole-exome sequencing data.
• Comparison of tumor tissue with adjacent normal kidney tissue.

Main Results:

• Uncovered prognostic genetic alterations and distinct molecular subgroups within WT.
• Identified three molecular subgroups based on proteome and transcriptome data, correlating with histopathology and developmental origins.
• EHMT2 identified as a prognostic biomarker and therapeutic target linked to epigenetic regulation and Wnt/β-catenin pathway.

Conclusions:

• Provides a comprehensive molecular characterization of Wilms tumor.
• Offers insights into WT pathogenesis and identifies potential therapeutic avenues.
• Establishes a foundational resource for future WT research and drug development.
