来自各种组织的正常干细胞与其更分化的后代相比显示出独特的代谢特性。然而,对癌症干细胞(也称为肿瘤起始细胞(TIC))代谢特性的异质性知之甚少。在这项研究中,我们表明,类似于一些正常的干细胞,乳腺TIC具有不同的代谢特性相比,非致瘤性癌细胞(NTCs)。使用RNA-Seq的转录组分析揭示了TIC低表达参与线粒体生物学和线粒体氧化磷酸化的基因,并且代谢分析揭示了与NTC相比,TIC优先进行糖酵解而不是氧化磷酸化。机制分析表明,丙酮酸脱氢酶(Pdh)的表达和活性降低,氧化磷酸化的关键调节剂,在促进TIC的促糖酵解表型中发挥关键作用。通过Pdh的强制激活的代谢重编程在体外和体内优先消除TIC。我们的研究结果揭示了TIC独特的代谢特性,并证明代谢重编程是靶向这些细胞的有希望的策略。
Normal stem cells from a variety of tissues display unique metabolic properties compared to their more differentiated progeny. However, relatively little is known about heterogeneity of metabolic properties cancer stem cells, also called tumor initiating cells (TICs). In this study we show that, analogous to some normal stem cells, breast TICs have distinct metabolic properties compared to non-tumorigenic cancer cells (NTCs). Transcriptome profiling using RNA-Seq revealed TICs under-express genes involved in mitochondrial biology and mitochondrial oxidative phosphorylation and metabolic analyses revealed TICs preferentially perform glycolysis over oxidative phosphorylation compared to NTCs. Mechanistic analyses demonstrated that decreased expression and activity of pyruvate dehydrogenase (Pdh), a key regulator of oxidative phosphorylation, play a critical role in promoting the pro-glycolytic phenotype of TICs. Metabolic reprogramming via forced activation of Pdh preferentially eliminates TICs both in vitro and in vivo. Our findings reveal unique metabolic properties of TICs and demonstrate that metabolic reprogramming represents a promising strategy for targeting these cells.
