ABSTRACT
<p><b>OBJECTIVE</b>To study survivin expression in human hepatoma cells and the effects of survivin siRNA on the malignant phenotypes of human hepatocellular cell line HCCLM6.</p><p><b>METHODS</b>Four hepatocellular carcinoma (HCC) cell lines were used. Semi-quantitative RT-PCR and Western blot were used to measure and compare their survivin expressions. The siRNA expression vector pshRNA-survivin targeting the mRNA of survivin and vector pGPU6/GFP/Neo-NC (as a control) were constructed, and then transfected into HCCLM6 cells. FQ-PCR was used to quantify the mRNA levels of survivin. The malignant phenotypes of transfected HCCLM6 cells, including invasive activities and adhesive capabilities, were analyzed.</p><p><b>RESULTS</b>Survivin expression gradually increased with the increase of the invasion and metastasis behaviors of the four HCC cell lines (P<0.05). The expression of survivin was highest in cell line HCCLM6. Survivin mRNA level was decreased by 93.500%+/-3.117% after the pshRNA-survivin transfection. The cell adhesion rates significantly decreased in the cells transfected with pshRNA-survivin (cell adhesion rates were 11.403%+/-1.256% vs 32.545%+/-1.367%, t=20.732, P<0.01). The migrating number of HCCLM6 cells (13.5+/-0.9) transfected with pshRNA-survivin was also significantly decreased (t=14.5, P<0.01) as compared with the control group (32.6+/-1.4).</p><p><b>CONCLUSION</b>The expression of survivin in HCC might have a close relationship to their invasion and metastasis properties. Sequence-specific shRNA can significantly reduce the survivin expression in the HCCLM6 cell line. Suppression of survivin expression in HCCLM6 cells transfected with pshRNA-survivin can reduce their invasive and adhesive capabilities.</p>
