| 摘 要： | 目的探讨抗HER-2嵌合抗体chA21在体外抑制高表达HER-2的人乳腺癌SKBR3细胞增殖并诱导其凋亡的作用。方法采用MTT比色法、HE染色、透射电镜、流式细胞术(FCM)、原位末端标记技术(TUNEL)等方法观察和检测chA21对人乳腺癌SKBR3细胞增殖的抑制和凋亡的诱导。结果chA21(0.2～5.4mg.L~(-1))可抑制SKBR3细胞的增殖并诱导其凋亡,其作用呈剂量和时间依赖性。结论chA21在体外可抑制SKBR3细胞的增殖,诱导其凋亡是其主要作用途径之一。

| Abstract: | Aim To explore the effects of anti-HER-2 chimeric antibody chA 21 on proliferation and apoptosis of SKBR3 cells.Methods MTT colorometric assay,HE staining,transmission electron microscopy,flow cytometry,and TUNEL were used to study the proliferation inhibition and apoptosis induction of SKBR3 cells by chA 21 in vitro.Results Proliferative inhibition rates and apoptotic index of SKBR3 cells were increased in a dose and time dependent manner after exposure to chA21(0.2～5.4 mg·L~(-1)).Conclusion chA 21 could remarkably inhibit proliferation of SKBR3 cells in vitro and apoptosis induction may be one of its main mechanisms. |
