英文摘要

Renal cancer is a relatively common malignant carcinoma that metastasizes to bone. The chemokine stromal derived factor-1 (SDF-1) and its corresponding receptor CXCR4 have been shown to regulate organ-specific metastasis in other cancer types. Based on this observation, we predicted that the expressions of SDF-1 and CXCR4 play a role in renal carcinoma metastasis to bone. To investigate the expressions of SDF-1 and CXCR4, and to assess the correlation between SDF-1 and CXCR4 immunoreactivity in bone metastasis of renal carcinoma, we collected 10 in situ renal carcinoma samples and 30 bone metastasis samples. We analyzed SDF-1 and CXCR4 expression with immunohistochemical analysis on paraffin-embedded sections. Compared with primary renal carcinomas, the SDF-1 expression in bone metastases was significantly higher [80% (24/30) vs. 30% (3/10), P = 0.006]; the expression of CXCR4 was also higher [83.3% (25/30) vs. 40% (4/10), P = 0.014]. Pearson correlation analysis supports a positive correlation between SDF-1 and CXCR4 in bone metastasis of renal carcinoma. In addition, RT-PCR demonstrated that, as compared with in situ renal carcinoma tissues, SDF-1 expression was predominant in the bone metastasis samples (P = 0.001), while CXCR4 was overexpressed in the bone metastasis tissues (P = 0.028). Western blot analysis confirmed these trends. Our data suggest that the expression of SDF-1/CXCR4 is high in bone metastases and over-expression of SDF-1/CXCR4 may play important roles in the bone metastasis of renal carcinoma.
