摘要
Abstract
Objective:To study the synergy inhibition effects of Oxymatrine combine with 5-FU on proliferation and apoptosis of SGC7901 human gastric cancer cells and its mechanism. Methods:SGC7901 cells were treated by different concentrations of Oxymatrine with or without 10. 0 mg/L 5-FU for 24,48 and 72 h. The cells proliferative vitality was detected by MTT assay,and the ap-optosis of SGC7901 cells was detected by HOECHST stain. Immunohistochemistry was applied to examine the protein expression of VEGF. The transcriptions of VEGF mRNA were distinguished by RT-PCR technique. Results:Compared with control group,middle dose and high dose concentration of Oxymatrine groups,and groups of its combined with 5-FU can inhibit the proliferation and induced the apoptosis of SGC7901 cancer cells. Compared with 5-FU group, the inhibition rate and apoptosis rate were significantly increased in groups of Oxymatrine combined with 5-FU. The mRNA and protein expression of VEGF were significantly decreased in groups of Oxymatrine and it combined with 5-FU. Conclusion:Synergy inhibition effects of Oxymatrine combine with 5-FU on proliferation and apoptosis of SGC7901 human gastric cancer cells were found,which may be related to strengthen the effects of Oxymatrine of inhibiting angiogenesis relate with down-regulating the expression of VEGF.关键词
