Abstract

In the studies of chemoprevention, the Nrf2-ARE signaling pathway has received widespread attention due to its anti-inflammatory and anti-oxidation effects. Our previous study indicated that atractylenolide II, which is an active component of , is a potential activator of Nrf2-ARE signaling pathway. In this study, we observed that atractylenolide II significantly increased Nrf2 expressing, nuclear translocation and the expression of its downstream detoxifying enzymes, thus decreasing 17β-Estradiol induced malignant transformation in MCF 10A cells, and we found that atractylenolide II acted through JNK/ERK-Nrf2-ARE pathway. Furthermore, atractylenolide II significantly reduced N-Nitroso-N-methylurea induced tumor incidence, multiplicity and volume, with activation of Nrf2-ARE pathway and decreased inflammation and oxidative stress in rat mammary tissue. Collectively, our results suggested that atractylenolide II could protect against mammary tumorigenesis both and via activating Nrf2-ARE signaling pathway, which supported atractylenolide II as a novel chemopreventive agent of breast cancer.

摘要

在化学预防研究中,Nrf2-ARE信号通路因其抗炎和抗氧化作用而受到广泛关注。我们之前的研究表明,白术内酯II作为[此处原文缺失相关成分]的活性成分,是Nrf2-ARE信号通路的潜在激活剂。在本研究中,我们观察到白术内酯II显著增加Nrf2的表达、核转位及其下游解毒酶的表达,从而减少17β-雌二醇诱导的MCF 10A细胞恶性转化,并且我们发现白术内酯II通过JNK/ERK-Nrf2-ARE途径发挥作用。此外,白术内酯II显著降低N-亚硝基-N-甲基脲诱导的大鼠乳腺肿瘤发生率、肿瘤数量和肿瘤体积,激活Nrf2-ARE途径并减轻大鼠乳腺组织中的炎症和氧化应激。总体而言,我们的结果表明白术内酯II可通过激活Nrf2-ARE信号通路预防[此处原文缺失相关内容]和[此处原文缺失相关内容]的乳腺肿瘤发生,这支持白术内酯II作为一种新型的乳腺癌化学预防剂。
