Exosomes and Hepatocellular Carcinoma: From Bench to Bedside

Area of Science:

• Oncology
• Cell Biology
• Biochemistry

Background:

• Hepatocellular carcinoma (HCC) often arises in patients with cirrhosis, limiting treatment options due to impaired liver function.
• Exosomes are nanoscale vesicles originating from endosomes, facilitating intercellular transfer of molecules like proteins, DNA, and RNA (miRNA, lncRNA, mRNA).
• Exosomes play a role in HCC development and intercellular communication involving tumor-associated cells.

Purpose of the Study:

• To review the utility of exosomes in the diagnosis, treatment, and prognosis prediction of hepatocellular carcinoma (HCC).
• To highlight exosomes as potential diagnostic biomarkers and therapeutic targets for HCC.
• To summarize the role of exosome-mediated molecular transfer in HCC pathogenesis.

Main Methods:

• Literature review of recent studies on exosomes and HCC.
• Analysis of exosomal components (proteins, miRNAs, lncRNAs) in relation to HCC.
• Evaluation of exosome-mediated intercellular communication in HCC development.

Main Results:

• Exosomes contain proteins, miRNAs, and lncRNAs that can serve as potential biomarkers for early-stage HCC diagnosis.
• Exosomes are implicated in the development and progression of HCC through molecular transfer.
• Exosomes represent promising targets for novel HCC therapeutic strategies.
• Exosomal biomarkers can aid in predicting the prognosis of HCC patients.

Conclusions:

• Exosomes are valuable tools for HCC diagnosis, offering potential biomarkers for early detection.
• Exosomes present novel therapeutic avenues for HCC treatment.
• Further research is essential to fully harness the potential of exosomes in managing HCC.
