摘要: 目的:研究血管内皮细胞生长因子(VEGF)-反义寡核苷酸(ASODN)转染涎腺腺样囊性癌(salivany adenoid cystic cancinoma, SACC)ACC-2细胞对其VEGF表达和生长的抑制作用。 方法:  人工合成硫代磷酸化VEGF-ASODN,转染SACC-2细胞,24 h后原位杂交及免疫组织化学法检测细胞VEGF mRNA及蛋白表达,ELISA法检测培养液上清中VEGF-ASODN能显著降低VEGF mRNA及蛋白水平、降低培养液中VEGF蛋白含量、增加细胞凋亡、抑制细胞活性及生长。结论: VEGF-ASODN转染SACC-2细胞能显著抑制VEGF mRNA及蛋白表达、增加细胞凋亡、抑制细胞生长。

Abstract: Objective: The study was designed to observe whether VEGF-antisense oligonucleotide (VEGF-ASODN) transfection to SACC-2 cells are associated with its expression of vascular endothelial growth factor (VEGF) and its′ pathological significances. Methods: The VEGF-ASODN was synthesized artificially with phosphorothioic acid. After transfecting with VEGF-ASODN into SACC-2, the quantity of VEGF mRNA and protein was detected by in situ hybridization and immunohistochemistry. The quantity of VEGF protein in supernatant was detected by ELISA. Flow Cytometry  and MTT assay were used to detect cell activity and cellular apoptosis. SPSS 13.0 software was used for statistical analysis. Results: VEGF mRNA protein levels within the cells and in culture medium both  decreased significantly after transfected by VEGF-ASODN (P<0.01,P<0.05). The ratio of SACC-2 cell apoptosis was increased. The activities of cells were also decreased after transfected by VEGF-ASODN (P<0.01). Conclusion: Transfection with VEGF-ASODN in SACC-2 can markedly inhibit expression of VEGF. It can enhance cellular apoptosis and suppress pathological growth of these cells.
