Exosomes in early detection of urological Cancer

Area of Science:

• Biochemistry
• Molecular Biology
• Oncology

Background:

• Exosomes, small extracellular vesicles, mediate intercellular communication by transferring biomolecules.
• They play roles in physiological and pathological processes, including modulating the tumor microenvironment (TME).
• Tumor-associated macrophages (TAMs) within the TME influence tumor progression.

Purpose of the Study:

• To review the significance of exosomes, particularly urinary exosomes (uEVs), as biomarkers for liquid biopsy.
• To highlight the role of uEVs in the diagnosis and management of urological cancers.
• To discuss challenges and future directions for clinical translation.

Main Methods:

• Literature review consolidating knowledge on exosomes and their role in urological cancers.
• Discussion of exosome composition and function in intercellular communication.
• Analysis of current challenges and technological advancements for uEV analysis.

Main Results:

• Exosomes carry functional proteins, metabolites, and nucleic acids, acting as critical mediators in the TME.
• Urinary exosomes (uEVs) offer a non-invasive diagnostic approach for urological cancers.
• Molecular contents of uEVs provide insights for early disease detection and monitoring.

Conclusions:

• Urinary exosomes are valuable biomarkers for non-invasive diagnosis and management of urological cancers.
• Standardization of protocols and addressing exosome heterogeneity are key for clinical translation.
• Advances in microfluidics, biosensors, and AI analytics can overcome current limitations, enabling integration into precision oncology.
