目的观察用β-氨基丙腈(β-aminopropionitrile,BAPN)抑制赖氨酰氧化酶(lysyl oxidase,LOX)对荷胃癌裸鼠肿瘤形成和转移的影响。方法 6周龄的裸鼠,随机分为BAPN预处理组和对照组,预处理组10只,对照组15只。BAPN预处理组每天用BAPN 100mg.kg-1腹腔注射,对照组每天用相同体积的无菌PBS腹腔注射。2周后,以人胃癌细胞SGC-7901 1×107.mL-1建立荷胃癌裸鼠模型。肿瘤细胞接种4周后,比较成瘤率、瘤重和转移率。结果 BAPN预处理组平均瘤重高于对照组,P<0.05;BAPN预处理组的成瘤率和转移率与对照组的差异无统计学意义。结论用BAPN预先抑制LOX活性后,肿瘤的重量明显增加,但对原发肿瘤形成和转移未见明显作用。 相似文献

目的 研究赖氨酰氧化酶(lysyl oxidase,LOX)对胃癌细胞MGC-803和BGC-823体外血管生成拟态(vasculogenic mimicry,VM)的影响.方法 培养胃癌细胞,分别加入含有不同浓度LOX或LOX的抑制剂β-氨基丙腈(beta-aminopropionitrile,BAPN)作用72h,用过碘酸雪夫(periodic acid-schiff stain,PAS)染色方法检测VM形成的数量.结果 在两种胃癌细胞株中,随着LOX浓度的增加,VM形成的数量也增加,LOX浓度与VM的形成呈正相关(r=0.847和r=0.851);此效应可被BAPN抑制,随着BAPN的浓度增加,VM形成的数量相应减少,BPAN与VM的形成呈现负相关(r=-0.791和r=-0.834).结论 外源性添加LOX可以促进胃癌MGC-803和BGC-823细胞株VM的形成. 相似文献

Objective To study the effects of lysyl oxidase ( LOX) on the migration and adhesion of the human gastric cancer cell line HGC-27 cells in vitro. Methods The human gastric cancer cell line HGC-27 cells were cultured in vitro, and treated with different concentration of β-aminopropionitrile (BAPN). The ability of migration was assessed by wound-healing assay. The ability of adhesion was detected by homogenous and heterogeneous adhesion experiments. Results Compared that with 0 mmol/L BAPN, the ability of migration of the cells after treatment with 0.2 mmol/L BAPN was descended at 8, 24, 32 and 48 h; the number of cells with homogeneous adhesion was increased from (6.97 ± 0.07) x l03/ml to (7.78±0.11) ×103/ml; and the number of cells with heterogeneous adhesion was decreased from (8.98± 0. 15) x 103/ml to (8. 35 ±0. 10) ×103/ml, both <0. 05. Compared with that of cells treated with 0 mmol/L and 0.2 mmol/L BAPN, the migration ability of cells after treatment with 0.3 mmol/L BAPN was descended at 8, 24, 32 and 48 h; the number of cells with homogeneous adhesion was raised to (8. 02 ± 0. 11) ×103/ml and the number of cells with heterogeneous adhesion was down to (7.93 ±0.07) ×103/ml (P < 0. 05). Conclusion LOX may promote the metastasis of cancer cells by enhancing invasion, increasing heterogeneous adhesion and decreasing homogeneous adhesion. 相似文献
