Hypothesis
To identify the roles of CXCL12 and CXCR4 and the associated mechanism involved in perineural invasion of prostate cancer.
Conclusion
CXCL12 and its receptor CXCR4 along with MMP-2 and MMP-9 are related with prostate cancer perineural invasion.
Supporting Evidence
- CXCL12 and CXCR4 expression levels were significantly higher in prostate cancer tissues compared to hyperplastic tissues.
- In vitro, CXCL12 increased the invasiveness of PC3 prostate cancer cells.
- In vivo, CXCL12 treatment resulted in a higher number of nerves around tumor tissue compared to control and AMD3100-treated groups.
Takeaway
This study found that a protein called CXCL12 helps prostate cancer cells invade nearby nerves, which can make the cancer spread more easily.
Methodology
The study used immunohistochemical staining and in vitro and in vivo experiments to assess the expression and effects of CXCL12 and CXCR4 on prostate cancer cell invasiveness.
Participant Demographics
The median age of prostate cancer patients was 68.40 years, with a range from 57 to 85 years.
