ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of sophoridine on the transplanted solid tumor SW480 and the expression of p53 and vascular endothelial growth factor (VEGF) in the tumor in nude mice.</p><p><b>METHODS</b>The nude mouse model bearing transplanted solid tumor SW480 was established, and the changes in the volume and weight of the tumor were determined after treatment of the mice with sophoridine. Western blotting and immunohistochemistry were employed to examine the expressions of p53 and VEGF proteins, respectively, and fluorescence quantitative PCR used to detect their mRNA expressions in the tumor tissue.</p><p><b>RESULTS</b>The volume and weight of the tumor xenograft in sophoridine group decreased in comparison with those in the control group. Sophoridine treatment resulted in lowered expressions of p53 and VEGF at both the protein and mRNA levels in the tumor explants as compared with the control group, with a tumor inhibition rate of 34.07% in nude mice.</p><p><b>CONCLUSION</b>Sophoridine can inhibit the growth of transplanted solid tumor of human SW480 cell line, the mechanism of which involves the inhibition of p53 and VEGF expression.</p>
