Extracellular vesicles-mediated noncoding RNAs transfer in cancer

Area of Science:

• Biochemistry
• Molecular Biology
• Oncology

Background:

• Extracellular vesicles (EVs) mediate intercellular communication via cargo transfer.
• Noncoding RNAs (ncRNAs) within EVs, including microRNAs, long noncoding RNAs, and circular RNAs, are increasingly recognized for their biological roles.

Purpose of the Study:

• To review the properties and functions of EV-associated ncRNAs.
• To explore the significance of EV-associated ncRNAs in cancer biology.
• To highlight their potential as diagnostic biomarkers and therapeutic targets in oncology.

Main Methods:

• Literature review of studies on extracellular vesicles and noncoding RNAs.
• Analysis of ncRNA content and function within EVs.
• Evaluation of ncRNAs' role in cancer pathogenesis and progression.

Main Results:

• EVs facilitate cell-to-cell communication by transferring diverse ncRNAs.
• EV-associated ncRNAs regulate key genes involved in tumorigenesis.
• These ncRNAs are stable and abundant in biofluids like serum.

Conclusions:

• EV-associated ncRNAs are crucial players in cancer development.
• Their stability and accessibility make them promising biomarkers for cancer diagnosis.
• Targeting these ncRNAs offers a potential new therapeutic strategy for cancer treatment.
