Objective: To investigate the inhibitory effect of survivin antisense oligonucleotide (ASODN) on the expression of survivin gene and proliferation of human hepatocellular carcinoma cell line SMMC-7721. Methods: The 20 mer antisense oligonucleotide (ASODN) targeted to the promoter region of survivin mRNA was designed and synthesized. The expression of survivin gene in hepatocellular carcinoma cell line SMMC-7721 was blocked by means of ASODN transfection mediated by DOTAP liposomal reagent. The changes of survivin protein and mRNA expression after transfection were as-sessd by Western blot and in situ hybridization, respectively. The apoptotic rate was detected by flow cytometer. The changes of cell adherent rate, cell growth activity, and the inhibitory rate of cell growth were also studied. Results: The expression of survivin protein and mRNA were decreased markedly after survivin ASODN transfection. Meanwhile, the cell adherent rate also decreased markedly while the apoptotic rate increased markedly. Conclusions: Transfection of ASODN targeted to the promotor region of survivin mRNA by DOTAP liposomal transfection reagent could down-regulated the expression of survivin protein and mRNA significantly in 7721 cell line and inhibit the proliferation of cancer cells. Survivin could be an important target in the therapy of hepatocellular carcinoma.

Background Tumstatin is the most active endogenous angiogenesis inhibitor,which has a marked inhibitory effect on pathological neovascularization,and Tum5 is an angiogenesis inhibitors fragment of fulllength tumstatin.Objective This study was to investigate the effects of adenovirus-mediated overexpression of recombinant Tum5 gene on the proliferation,migration and tube formation of human umbilical vein endothelial cells (HUVECs) in physiological status.Methods The empty adenoviral vector expressing green fluorescent protein (rAd-GFP) and the viral vector expressing recombinant Tum5 gene were constructed.The HUVECs cultured in RPMI1640 medium were divided into normal control group,empty vector group (rAd-GFP group) and Tum5 gene infection group (rAd-GFP-Tum5 group).The rAd-GFP and rAd-GFP-Tum5 adenoviral particles at the density of 1 × 1010/ml were added into the medium to infect the cells for 48 hours.The proliferation of the cells was assayed at 24,48 and 72 hours by cell counting kit-8 (CCK-8) to evaluate the proliferative rate;the migration number of the cells was detected at 48 hours after infection by Transwell chamber;the tube formation number of the cells were detected by Matrigel method.The concentration of vascular endothelial growth factor (VEGF) in cell supernatants was assayed by ELISA at 24,48,and 72 hours following adenoviral infection.Results The cultured cells showed green fluorescence in the rAd-GFP group and rAd-GFP-Tum5 group under the inverted fluorescence microscope,and the infection efficiency of rAd-GFP and rAd-GFP-Tum5 was 55.13％ and 50.31％,respectively.No significant difference was found in cell proliferative rate among normal control group,rAd-GFP group and rAd-GFP-Tum5 group both at 24 and 48 hours after infection (both at P＞0.05),and the cell proliferative rate was significantly lower in the rAd-GFP-Tum5 group than that in the normal control group and rAd-GFP group at 72 hours after infection (both at P＜0.01).The migration number of the cells at 48 hours after infection was 2 260.25-±930.44,2 370.00±441.06 and 723.75± 363.80 in the normal control group,rAd-GFP group and rAd-GFP-Tum5 group,showing a significant difference among the groups (F =8.524,P =0.008),and the migrated cells were evidently decreased in the rAd-GFP-Tum5 group compared with the rAd-GFP group and the normal control group (both at P＜ 0.01).The tube number at 48 hours after infection was 95.67±5.86,88.00±4.58 and 20.67±3.51 in the normal control group,rAd-GFP group and rAdGFP-Tum5 group,showing a significant difference among the groups (F=226.498,P＜0.01),and the tube number in the rAd-GFP-Tum5 group was significantly reduced in comparison with the normal control group and rAd-GFP group (both at P＜ 0.01).The considerably differences in VEGF concentration in the cell supernatants were found in different groups and various time points (Fgroup =73.260,P＜0.01;Ftime =73.477,P＜0.01),and VEGF concentration in the cell supernatants was significantly decreased in the rAd-GFP-Tum5 group compared with the rAd-GFP group at both 48 hours and 72 hours (both at P＜0.01).Conclusions The overexpression of the recombinant Tum5 can inhibit the proliferation,migration and tube formation of the HUVECs in physiological status,which may be associated with Tum-5-mediated down-regulation of VEGF protein in the cell supernatant.
