摘要: 目的: 探讨阿霉素对荷瘤鼠MCF-7 乳腺癌细胞凋亡和增殖的影响。方法: 建立小鼠MCF-7 乳腺癌细胞模型, 用TUNEL 法和免疫组化法检测阿霉素作用下MCF-7 乳腺癌细胞的凋亡和PCNA 表达的变化。结果: 1.25 mg·kg-1 阿霉素的抑瘤率为43 %。MCF-7 乳腺癌细胞的凋亡指数为1.93 %, 较荷瘤对照组的1.11 %明显升高(P <0.05)。增殖指数为35.75 %, 较荷瘤对照组的56.38 %明显下降(P <0.01)。结论: 阿霉素有诱导小鼠MCF-7 乳腺癌细胞凋亡和抑制其增殖的作用。

Abstract: AIM: To observe the apoptosis and cell proliferation induced by adriamycin in mice with breast cancer. METHODS: Therapeutic effect of 1.25 mg·kg-1 adriamycin (ADR)on mice MCF-7 breast cancer was observed in vivo. Apoptosis and PCNA of tumor cells were also studied by TUNEL and immune his to chemical methods. RESULTS: In the control group, the apoptotic cell index (AI)in tumor cell was 1.11 %and PCNA index (PI)was 56.38 %.In the ADR group, the rate of tumor inhibition was 43 % and the AI was 1.93 % (P <0.05).The 35.75 % of PI in ADR group was lower than that in the control group (P <0.01). CONCLUSION: Adriamycin may induce apoptosis and reduce cell proliferation.

Key words: adriamycin, breast neoplasm, apoptosis, PCNA
