ABSTRACT
Objective To investigate the role of a small RNA interference against VEGF in radiation sensitivity in melanoma .Methods A375 human melanoma cell lines were transplanted into nude mice ,which with malignant melanoma were randomly divided into control group , VEGF negative plasmid group and VEGF positive plasmid group, followed by 4Gy irradiation twice a week for 2 weeks.The volume of tumor was calculated twice a week, the area of tumor necrosis was assayed by HE,the expression of VEGF in tumor was determined by Western-blot and Immunohistochemical. ResuIts The expression of VEGF in VEGF positive plasmid group decreased significantly (P<0.05), VEGF positive group had more tissue necrosis, tumor growth was significantly inhibited (P<0.05).ConcIusion siRNA-VEGF in tumor injection liposome encapsulated in malignant melanoma has a role in the radiation sensitization, which provides an experimental basis for the clinical development of targeted therapy combined with radiotherapy for the treatment of VEGF gene.
