鱼藤素是一种从几种植物中分离出来的天然类鱼藤素,据报道在各种癌症中发挥抗肿瘤作用。然而,这种调节的分子机制仍有待充分阐明。在这里,我们发现鱼藤素通过下调Bmi1表达在体外和体内抑制非小细胞肺癌(NSCLC)细胞的生长。我们的数据显示Bmi 1在人类非小细胞肺癌组织和细胞系中高度表达。Bmi 1的敲除显著抑制NSCLC细胞增殖和集落形成。鱼藤素处理减弱了Bmi1与Noxa启动子的结合活性,从而导致Noxa转录和凋亡激活。敲低Bmi1可促进Noxa表达并增强鱼藤素诱导的细胞凋亡,而过表达Bmi1则下调Noxa蛋白水平和鱼藤素诱导的细胞凋亡。总的来说,我们的研究证明了鱼藤素在NSCLC细胞中发挥其抗肿瘤活性的一种新的凋亡机制。
Deguelin, a natural rotenoid isolated from several plants, has been reported to exert anti‐tumour effects in various cancers. However, the molecular mechanism of this regulation remains to be fully elucidated. Here, we found that deguelin inhibited the growth of non‐small cell lung cancer (NSCLC) cells both in vitro and in vivo by downregulation of Bmi1 expression. Our data showed that Bmi1 is highly expressed in human NSCLC tissues and cell lines. Knockdown of Bmi1 significantly suppressed NSCLC cell proliferation and colony formation. Deguelin treatment attenuated the binding activity of Bmi1 to the Noxa promoter, thus resulting in Noxa transcription and apoptosis activation. Knockdown of Bmi1 promoted Noxa expression and enhanced deguelin‐induced apoptosis, whereas overexpression of Bmi1 down‐regulated Noxa protein level and deguelin‐induced apoptosis. Overall, our study demonstrated a novel apoptotic mechanism for deguelin to exert its anti‐tumour activity in NSCLC cells.
