Title

DOWNREGULATION OF VASCULAR ENDOTHELIAL GROWTH FACTOR ENHANCES CHEMOSENSITIVITY BY INDUCTION OF APOPTOSIS IN HEPATOCELLULAR CARCINOMA CELLS

Pages

  273-287

Abstract

 Objective: Hepatocellular carcinoma (HCC), one of the most common cancers worldwide, is resistant to anticancer drugs. Angiogenesis is a major cause of tumor resistance to chemotherapy, and VASCULAR ENDOTHELIAL GROWTH FACTOR (VEGF) is a key regulator of angiogenesis. The purpose of this study is to investigate the impact of small-interfering RNA targeting VEGF gene (VEGF-siRNA) on chemosensitivity of HCC cells in vitro.Materials and Methods: In this experimental study, transfection was performed on Hep3B cells. After transfection with siRNAs, VEGF mRNA and protein levels were examined. Cell proliferation, APOPTOSIS and anti-apoptotic gene expression were also analyzed after treatment with VEGF-siRNA in combination with DOXORUBICIN in Hep3B cells.Results: Transfection of VEGF-siRNA into Hep3B cells significantly reduced the expression of VEGF at both mRNA and protein levels. Combination therapy with VEGF-siRNA and DOXORUBICIN more effectively suppressed cell proliferation and induced APOPTOSIS than the respective monotherapies. This could be explained by the significant downregulation of B-cell lymphoma 2 (BCL-2) and SURVIVIN.Conclusion: VEGF-siRNA enhanced the chemosensitivity of DOXORUBICIN in Hep3B cells at least in part by suppressing the expression of anti-apoptotic genes. Therefore, the downregulation of VEGF by siRNA combined with DOXORUBICIN treatment has been shown to yield promising results for eradicating HCC cells.
