Prostate cancer (PCa) is the second most common cancer type among men globally. Most patients with PCa present with locally advanced or metastatic disease at the time of diagnosis, thus limiting the effectiveness of conventional treatment. The development of new diagnostic and therapeutic strategies for castration-resistant and chemo-resistant PCa is essential. Exosomes derived from PCa cells have shown great potential in the treatment and diagnosis of PCa.

The role of exosomes in prostate cancer

Exosomes deliver functional biomolecules, such as nucleic acids, lipids, and proteins to mediate the communication between cancer cells and stroma cells. Studies have shown that prostate cancer development, metastasis and chemoresistance are associated with exosomes loaded with these biomolecules, especially proteins, miRNAs, and lncRNAs. PCa cells regulate the surrounding stromal cells through exosomes, thereby regulating the microenvironment and promoting tumor growth and metastasis. Exosomes derived from PCa cells have been found to contribute to chemotherapy resistance in cancer. In addition, exosomes are promising carriers of drugs and other therapeutic molecules targeting PCa due to their high stability and low immunogenicity on lipid bilayer membranes. The isolation and detection of exosomes from body fluids can also be used for the non-invasive diagnosis of PCa.

  • Exosomes promote PCa progression, involving miR-139, miR-21 and miR-100 containing exosomes
  • Exosomes promote PCa cell growth along with metastasis, involving miRNA-21 and miRNA-139 containing exosomes
  • Exosomes regulate angiogenic activity in the tumor microenvironment, involving c-Src tyrosine kinase, insulin-like growth factor 1 receptor (IGF-R) and focal adhesion kinase (FAK) containing exosomes
  • PCa-originated exosomes enhance cancer cell evasion of immune response
