Non-Coding RNAs of Extracellular Vesicles: Key Players in Organ-Specific Metastasis and Clinical Implications

Area of Science:

• Oncology
• Molecular Biology
• Cell Biology

Background:

• Extracellular vesicles (EVs) are key mediators of intercellular communication.
• Non-coding RNAs (ncRNAs) within EVs play critical roles in biological processes.
• Cancer metastasis, particularly organ-specific metastasis, remains a leading cause of cancer mortality.

Purpose of the Study:

• To review the mechanisms of EV-delivered ncRNAs in common organ-specific metastases.
• To explore the clinical applications of EV-ncRNAs as biomarkers and therapeutic targets.
• To bridge the gap between basic research and clinical application in cancer metastasis.

Main Methods:

• Literature review of studies on extracellular vesicles and non-coding RNAs in cancer metastasis.
• Analysis of mechanisms by which EV-ncRNAs influence organ-specific metastasis.
• Synthesis of current knowledge on clinical potential of EV-ncRNAs.

Main Results:

• EVs are enriched with ncRNAs that promote organ-specific metastasis.
• Tumor-derived EV-ncRNAs influence metastasis to specific organs like liver, bone, lung, brain, and lymph nodes.
• Tissue-specific expression of EV-ncRNAs suggests diagnostic and therapeutic potential.

Conclusions:

• EV-ncRNAs are critical regulators of organ-specific metastasis.
• EV-ncRNAs hold significant promise as biomarkers for early detection and prognosis.
• Targeting EV-ncRNAs presents a novel therapeutic strategy for combating cancer metastasis.
