Extracellular vesicle long non-coding RNA-mediated crosstalk in the tumor microenvironment: Tiny molecules, huge...

Area of Science:

• Oncology
• Molecular Biology
• Cell Biology

Background:

• The tumor microenvironment is a complex ecosystem where cellular crosstalk influences cancer progression and treatment outcomes.
• Extracellular vesicles (EVs) are key mediators of intercellular communication, transferring bioactive molecules like long non-coding RNAs (lncRNAs) between cells.
• Dysregulation of EV-lncRNAs has been implicated in remodeling the tumor microenvironment and promoting aggressive cancer phenotypes.

Purpose of the Study:

• To review the role of EV-lncRNAs in mediating crosstalk between tumor and stromal cells within the tumor microenvironment.
• To explore the mechanisms of selective lncRNA sorting into EVs.
• To highlight the potential clinical applications of EV-lncRNAs in cancer diagnosis and treatment.

Main Methods:

• Literature review focusing on extracellular vesicle biology and lncRNA research in cancer.
• Analysis of studies investigating intercellular communication within the tumor microenvironment.
• Synthesis of current knowledge on EV biogenesis, cargo sorting, and functional impact.

Main Results:

• EVs, including exosomes, microvesicles, and apoptotic bodies, facilitate the transfer of lncRNAs between cancer cells and other cells in the tumor microenvironment.
• EV-lncRNAs can reprogram recipient cells, promoting tumor growth, metastasis, and resistance to chemotherapy.
• Specific mechanisms governing the selective packaging of lncRNAs into EVs are being elucidated.

Conclusions:

• EV-lncRNA-mediated crosstalk is a critical factor in cancer development and progression.
• Targeting EV-lncRNA pathways offers promising avenues for innovative cancer therapies.
• Further research into EV-lncRNA sorting mechanisms could lead to improved diagnostic biomarkers and therapeutic strategies.
