Hepatocellular carcinoma (HCC) is a major cause of cancer-related death
worldwide. As vectors for intercellular information exchange, the potential role
of extracellular vesicles (EVs) in HCC formation, progression and therapy has
been widely investigated. In this review, we explore the current status of the
researches in this field. Altogether there is undeniable evidence that EVs play a
crucial role in HCC development, metastasis. Moreover, EVs have shown great
potential as drug delivery systems (DDSs) for the treatment of HCC. Exosomal
miRNAs derived from HCC cells can enhance transformed cell growth in recipient
cells by modulating the expression of transforming growth factor-? activated
kinase-1(TAK1) and downstream signaling molecules. Furthermore, vacuolar protein
sortin 4 homolog A(VPS4A) and insulin-like growth factor(IGF)-1 regulate
exosome-mediated miRNAs transfer. Immune cells- derived EVs containing integrin
?M?2 or CD147 may facilitate HCC metastasis. In addition, EVs-mediated shuttle of
long non-coding RNAs (lncRNAs), specifically linc- VLDLR and linc-ROR promote
chemoresistance of malignant cells. Heat shock proteins (HSPs)-harboring exosomes
derived from HCC tumor cells increase the antitumor effect of natural killer (NK)
cells, thus enhancing HCC immunotherapy. Indeed, inhibition of HCC tumor growth
has been associated with tumor cell-derived exosomes (TEX)-pulsed dentritic cells
(DCs). Exosomes are also essential in liver metastasis during colorectal
carcinoma (CRC) and pancreatic ductal adenocarcinomas (PDAC). Therefore, as
nucleic acid and drug delivery vehicles, EVs show a tremendous potential for
effective treatment against HCC.
