胶质母细胞瘤(GBM)干细胞(GSC)存在于肿瘤内的缺氧和血管微环境中。允许GSC占据这种对比生态位的分子机制尚不清楚。我们使用患者来源的GBM培养物来鉴定具有Notch信号传导差异激活的GSC亚型,其在肿瘤中共存,但占据不同的小生境并相应地匹配其代谢。具有Notch途径激活的多能GSC位于血管周围的小生境中,并且在缺氧期间不能进行无氧糖酵解。相比之下,大多数表达CD133的GSC不依赖于经典的Notch信号传导,无论局部血管分布如何,都能在肿瘤中增殖,并选择性地利用厌氧糖酵解在缺氧中扩增。表达CD133的GSC中Notch信号传导的异位激活足以抑制无氧糖酵解和耐缺氧。这些发现证明了Notch信号在调节GSC代谢中的新作用,并表明肿瘤内GSC异质性确保代谢适应以支持肿瘤在不同肿瘤微环境中的生长。
Glioblastoma (GBM) stem cells (GSCs) reside in both hypoxic and vascular microenvironments within tumors. The molecular mechanisms that allow GSCs to occupy such contrasting niches are not understood. We used patient-derived GBM cultures to identify GSC subtypes with differential activation of Notch signaling, which co-exist in tumors but occupy distinct niches and match their metabolism accordingly. Multipotent GSCs with Notch pathway activation reside in perivascular niches, and are unable to entrain anaerobic glycolysis during hypoxia. In contrast, most CD133-expressing GSCs do not depend on canonical Notch signaling, populate tumors regardless of local vascularity and selectively utilize anaerobic glycolysis to expand in hypoxia. Ectopic activation of Notch signaling in CD133-expressing GSCs is sufficient to suppress anaerobic glycolysis and resistance to hypoxia. These findings demonstrate a novel role for Notch signaling in regulating GSC metabolism and suggest intratumoral GSC heterogeneity ensures metabolic adaptations to support tumor growth in diverse tumor microenvironments.
