CC chemokine receptor 2 (CCR2) is highly expressed in aggressive prostate cancer (PCa). Higher CCR2 levels correlate with advanced PCa, suggesting its role in disease progression.

Area of Science:

  • Oncology
  • Immunology
  • Molecular Biology

Background:

  • Chemokines and their receptors primarily regulate leukocyte trafficking in inflammation.
  • Emerging evidence indicates chemokines also play significant roles in cancer development.
  • Monocyte chemoattractant protein-1 (MCP-1) has been implicated as a growth and invasion factor in prostate cancer (PCa).

Purpose of the Study:

  • To investigate the potential role of CC chemokine receptor 2 (CCR2) in prostate cancer progression.
  • To determine CCR2 expression levels in various cancer cell lines and prostate cancer tissues.
  • To correlate CCR2 expression with clinical parameters of prostate cancer.

Main Methods:

  • Assessed CCR2 mRNA and protein expression in multiple cancer cell lines using RT-PCR and Western blotting.

  • Analyzed CCR2 expression in prostate cancer tissues using real-time RT-PCR and immunohistochemical staining.
  • Correlated CCR2 expression with existing gene array data (ONCOMINE) and patient clinical data (Gleason score, pathologic stage).

    • Main Results:

    • CCR2 mRNA and protein were expressed in all tested cell lines.
    • More aggressive PCa cell lines (C4-2B, DU145, PC3) exhibited higher CCR2 expression than less aggressive lines (LNCaP).
    • Elevated CCR2 mRNA levels were observed in metastatic PCa tissues compared to localized PCa or benign tissues.
    • Immunohistochemical analysis revealed that CCR2 protein expression positively correlated with Gleason score and clinical pathologic stage in PCa patients.

    Conclusions:

    • CCR2 is expressed in prostate cancer cells and tissues.
    • Higher CCR2 expression is associated with more aggressive disease and advanced stages of prostate cancer.
    • These findings suggest that CCR2 may be a contributing factor to prostate cancer development and progression.
