| 摘 要： | 目的：探讨抗癌生物活性肽对人胃癌细胞周期相关蛋白CDC2、CDK4的影响及其作用机制。方法：实验分为活性肽组及对照组,将不同浓度的抗癌生物活性肽按不同时间作用于培养的人胃癌细胞株（BGC-823）,应用MTT法检测增殖抑制率。建立荷胃癌裸鼠模型,给予生理盐水作为阴性对照组,应用免疫组化技术对抗癌生物活性肽作用前后的胃癌裸鼠肿瘤中CDK4、CDC2的表达进行检测。结果：不同浓度的抗癌生物活性肽对胃癌细胞均有增殖抑制作用;抗癌活性肽S-2作用后人胃癌组织中的CDK4表达明显低于对照组（P〈0.01）,而CDC2表达高于对照组（P〈0.01）。结论：抗癌生物活性肽具有抗胃癌细胞增殖作用,其抗肿瘤作用机制可能是通过下调CDK4和上调CDC2的表达实现。
