摘要 目的探讨慢性心理应激对panc-1荷瘤裸鼠移植瘤中细胞外基质金属蛋白酶诱导因子(EMMPRIN)和Ki-67蛋白水平的影响。方法将20只裸鼠随机分成单纯荷瘤组和荷瘤+应激组,每组10只,建立裸鼠胰腺癌移植瘤束缚应激模型,采用免疫组化检测移植瘤组织中EMMPRIN和Ki-67蛋白的表达。结果荷瘤+应激组移植瘤组织中EMMPRIN和Ki-67的阳性表达均明显高于单纯荷瘤组,差异有统计学意义(Z=-2.636,P<0.05);移植瘤组织中EMMPRIN与Ki-67的表达呈正相关(r=0.534,P<0.05)。结论应激可能通过上调EMMPRIN的表达,诱导肿瘤细胞增殖,促进裸鼠胰腺癌的生长。
