Abstract

Norsolorinic acid, isolated from the Aspergillus nidulans, was investigated for its antiproliferative activity in human breast adenocarcinoma MCF-7 cells. To identity the anticancer mechanism of norsolorinic acid, we assayed its effect on apoptosis, cell cycle distribution, and levels of p53, p21/WAF1, Fas/APO-1 receptor and Fas ligand. The results showed that norsolorinic acid induced apoptosis of MCF-7 cells without mediation of p53 and p21/WAF1. We suggest that Fas/Fas ligand apoptotic system is the main pathway of norsolorinic acid-mediated apoptosis of MCF-7 cells. Our study reports here for the first time that the activity of the Fas/Fas ligand apoptotic system may participate in the antiproliferative activity of norsolorinic acid in MCF-7 cells.

摘要

从构巢曲霉中分离出的降红曲酸,对其在人乳腺腺癌MCF-7细胞中的抗增殖活性进行了研究。为了确定降红曲酸的抗癌机制,我们检测了其对细胞凋亡、细胞周期分布以及p53、p21/WAF1、Fas/APO-1受体和Fas配体水平的影响。结果表明,降红曲酸可诱导MCF-7细胞凋亡,且不依赖p53和p21/WAF1的介导。我们认为,Fas/Fas配体细胞凋亡系统是降红曲酸介导MCF-7细胞凋亡的主要途径。我们的研究首次报道,Fas/Fas配体细胞凋亡系统的活性可能参与了降红曲酸在MCF-7细胞中的抗增殖活性。
