Promising Urology Bioinformatics Research Directions
The most promising research directions in urology bioinformatics focus on developing and validating urinary extracellular vesicle (uEV) biomarkers and implementing artificial intelligence methods for improved diagnosis, prognosis, and treatment selection in urological cancers. 1, 2
Urinary Extracellular Vesicles (uEVs) as Biomarkers
High-Priority Research Areas:
Validation of uEV biomarkers in large independent cohorts for prostate, bladder, and renal cancers 2
- Focus on protein, mRNA, miRNA, lipid, and metabolite markers
- Prioritize validation of promising candidates like PCA3 and TMPRSS2:ERG for prostate cancer
Standardization of uEV isolation and analysis protocols 2, 1
- Develop consensus on biospecimen handling and processing
- Create reproducible multi-site validation methodologies
- Address the analytical challenges of diverse origins and dynamic molecular composition
Development of uEV-based liquid biopsies 1
- For early detection of urological cancers
- For monitoring disease progression and treatment response
- For predicting treatment resistance
Artificial Intelligence Applications
Actionable Research Opportunities:
