齐墩果酸抗人肺癌细胞增殖、侵袭和诱导细胞凋亡的研究

Study on proliferation inhibition and anti-invasion and apoptotic induction of oleanolic acid in human lung cancer cell line

  • 摘要: 目的 研究齐墩果酸抗人肺癌细胞增殖、侵袭和诱导细胞凋亡的作用, 并探讨其抗侵袭作用的机理。方法 用细胞增殖抑制试验、软琼脂集落形成试验、对重建基底膜的侵袭试验、趋化运动试验、对层粘连蛋白的粘附试验以及组织蛋白酶B活性测定观察齐墩果酸对PGCL3细胞侵袭能力的影响, 用吖啶橙 -溴乙啶荧光双染法和TUNEL法检测细胞凋亡。结果 齐墩果酸可降低PGCL3细胞增殖能力并呈剂量依赖性, IC50 为 4 0 .71 μmol/L ;35 μmol/L和 4 5 μmol/L齐墩果酸均能抑制PGCL3细胞的侵袭能力 (P <0 .0 1 )且有剂量依赖性。抗侵袭作用机理的分析结果显示上述浓度的该药物对细胞的运动、粘附及组织蛋白酶B分泌均有明显的抑制作用 (P <0 .0 5和P <0 .0 1 ) ;软琼脂集落形成率也显著降低 ;上述浓度的药物处理 4 8h均使PGCL3细胞凋亡率显著升高 (P <0 .0 1 )。结论 齐墩果酸有抗PGCL3人肺癌细胞增殖和侵袭作用, 并有诱导PGCL3细胞凋亡的作用。其抗侵袭机理不是对侵袭的某一环节的阻断, 而是对侵袭各个基本环节都有抑制作用

     

    Abstract: Objective To study the effects on proliferation inhibition, anti invasion and apoptotic induction of oleanolic acid (OA) in human lung cancer cell line (PGCL3), and search the mechanism of anti invasion. Methods The proliferation inhibitive rate, the colony formation rate in semi solid agar, the invasive ability to reconstituted basement membrane, the chemotatic migration ability, the adhesion ability to laminin, and the activity of cathepsin B (CB) were tested to observe the effects of OA on invasion...
