ABSTRACT
PURPOSE:
The aim of this study is to know whether silibinin has an anticancer effect on triple negative breast cancer xenograft model using MDA-MB-468 cells.METHODS:
To establish the xenograft model, we injected the MDA-MB-468 cells into female Balb/c-nude mice. After establishing a xenograft model, oral silibinin was administered to the tested mice in the way of 200 mg/kg for 45 days. The difference of mean tumor volume between silibinin fed mice and control mice was analyzed. The epidermal growth factor receptor (EGFR) phosphorylation in MDA-MB-468 cells was analyzed by Western blotting. The expression of VEGF, COX-2, and MMP-9 genes in tumor tissue was analyzed by real-time polymerase chain reaction (PCR).RESULTS:
In the xenograft model using MDA-MB-468 cells, we found that oral administration of silibinin significantly suppressed the tumor volume (silibinin treated mice vs. control mice; 230.3 +/- 61.6 mm3 vs. 435.7 +/- 93.5 mm3, P < 0.001). The phosphorylation of EGFR in MDA-MB-468 cells was inhibited by treatment with 50 microg/mL of silibinin. In real time-PCR analysis of tumor tissue obtained from sacrificed mice, the gene expression of MMP-9, VEGF, and COX-2 was 51.8%-80% smaller in silibinin group than that of control group and we can also verify the similar result using Western blotting analysis.CONCLUSION:
We verified that silibinin had anticancer effect on xenograft model of MDA-MB-468 cells in the way of preventing the phosphorylation of EGFR and eventually suppressed the production of COX-2, VEGF, and MMP-9 expression. Finally, the tumor volume of xenograft models was decreased after administration of Silibinin.
