Functional tumor-derived exosomes in NSCLC progression and clinical implications

Area of Science:

• Oncology
• Cell Biology
• Biochemistry

Background:

• Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality, often diagnosed late and prone to metastasis and recurrence.
• Tumor-derived exosomes (TEXs) are key mediators in the NSCLC tumor microenvironment, facilitating intercellular communication.
• TEXs carry proteins, RNAs, and DNAs, reflecting tumor complexity and influencing cancer progression.

Purpose of the Study:

• To review the multifaceted roles of TEXs in NSCLC progression, including metastasis and immune modulation.
• To highlight the involvement of exosome-associated molecules in NSCLC growth and spread.
• To explore the potential of TEXs as diagnostic and prognostic biomarkers for NSCLC.

Main Methods:

• Literature review of studies investigating TEXs in NSCLC.
• Analysis of exosome-associated proteins and RNAs in NSCLC progression.
• Evaluation of TEXs as biomarkers for diagnosis, prognosis, and therapy response prediction.

Main Results:

• TEXs promote NSCLC metastasis through pre-metastatic niche formation and epithelial-mesenchymal transition (EMT).
• Exosomal molecules contribute to neovascularization, drug resistance, and immune evasion in NSCLC.
• TEXs are implicated in modulating the tumor immune microenvironment.

Conclusions:

• TEXs play diverse and critical roles in advancing NSCLC.
• Exosomal contents offer insights into NSCLC pathogenesis and progression.
• TEXs represent a promising avenue for developing novel biomarkers for NSCLC diagnosis, prognosis, and personalized therapy selection.
