摘要: 目的: 探讨奥曲肽抑制肝癌细胞生长的作用。方法: 人肝癌细胞SMMC-7721 培养于含10 %胎牛血清、100 U·ml-1青霉素、链霉素的RPMI1640 培养液中。以4 个稀释度10-5、10-4、10-3、10-2g·L-1将奥曲肽加入培养液,于加药后第48 h 行MTT 比色实验检测生长抑制率。奥曲肽浓度为10-3g·L-1时于0、6、12、24、36 h 行DNA 染色分析细胞周期。结果: MTT 比色法测定显示奥曲肽抑制肝癌细胞的生长,在浓度为10-5、10-4、10-3、10-2g·L-1作用48 h 生长抑制率分别为9.33 %、12.70 %、19.70 %、20.93 %。药物作用12、24 h,G0-G1 期细胞比例增加,G2-M 期细胞比例减少。结论: 奥曲肽抑制体外培养的人肝癌细胞的增殖,机制可能是将肝癌细胞阻滞于G0-G1 期,阻止细胞进入G2-M 期。

Abstract: AIM: To study the anti-cancer effects of octreotide on the proliferation of liver cancer cells. METHODS: The liver cancer cells SMMC-7721 were cultured in RPMI-1640 media with 10 % fetal bovine serum, 100 U·ml-1 penicillin and streptomycin.10-5 ,10-4, 10-3 and 10-2g·L-1 of octreotide were added and MTT colorimetric assay were used to detect the growth inhibition rate.DNA staining and cell cycle analysis were done at 0, 6, 12, 24 and 36 hours after medication when the concentration of octreotide was 10-3g·L-1.RESULTS: MTT colorimetric tests showed that octreotide suppressed the growth of liver cancer cells.48 hours after medication, the cell growth inhibition rate was 9.33 %, 12.70 %, 19.70 % and 20.93 % when the octreotide concentration was 10-5, 10-4, 10-3 and 10-2g·L-1 separately.Cell cycle analysis showed that the percentage of G0-G1 phase cells increased and the percentage of G2-M phase cells decreased.CONCLUSION: Octreotide inhibits the cultured liver cancer cells proliferation in vitro, its mechanisms may be related to preventing the G0-G1 phase cells from going into G2-M phase.
