人参皂甙Rg3对乳腺癌细胞(MCF-7)表达金属蛋白酶2、9(MMP-2,MMP-9)的影响

open access: yesZhongguo shiyan zhenduanxue, 2005
目的为了研究人参皂甙Rg3对乳腺癌细胞(MCF-7)细胞分泌的基质金属蛋白酶(MMP-2,MMP-9)表达的影响。方法免疫组化法测定了用人参皂甙Rg3前后MCF-7细胞基质金属蛋白酶(MMP-2,MMP-9)的表达。结果分析表明人参皂甙Rg3能减少MCF-7细胞基质金属蛋白酶(MMP-2,MMP-9)表达。结论人参皂甙Rg3能抑制基质金属蛋白酶MMP-2、MMP-9的分泌。

Establishment of gastric carcinoma cell clone with MMP-9 gene silence based on RNA interference [PDF]

open access: yes, 2010
恶性肿瘤的主要特征是浸润和转移。根据文献报道,在浸润和转移过程中,基底膜和细胞外基质(ECM)的降解是关键环节。基质金属蛋白酶-9(MMP-9)作为蛋白水解酶的一种,它能特异性降解基底膜和ECM成分,从而促进肿瘤的浸润、转移及间质血管新生。胃癌组织MMP-9检测结果与临床病理资料对比研究表明,该酶的表达往往与胃癌的分化程度、病理类型、临床病理分期、浸润、转移和预后有关。但是,MMP-9在RNA干扰后对胃癌的影响机制尚不清楚。 RNA干扰是通过dsRNA介导的同源mRNA降解引起的相应转录后基因沉默 ...
