胶质母细胞瘤(GBM)是一种原发性脑癌,含有干细胞样癌细胞(GSC)群体,这些干细胞样癌细胞(GSC)聚集在专门的血管周围小生境中。GSC与其生态位的相互作用影响自我更新,分化和耐药性,尽管这些事件的潜在途径在很大程度上仍然未知。在此,我们报道了整合素αvβ8及其潜在的转化生长因子β1(TGFβ1)蛋白配体在促进生态位共选择和GBM启动中的核心作用。αvβ8整合素在GSC中高度表达,并且对于体外自我更新和谱系定型是必需的。从新鲜切除的人GBM样品中分离β8high细胞也揭示了在体内肿瘤发生中对该整合素的需要。全转录组测序显示,αvβ8整合素部分通过驱动TGFβ1诱导的DNA复制和有丝分裂检查点进展来调节肿瘤发展。总之,这些数据确定αvβ8整合素-TGF β1信号传导轴对于利用血管周围小生境至关重要,并确定了抑制GBM患者肿瘤生长和进展的潜在治疗靶点。
Glioblastoma (GBM) is a primary brain cancer that contains populations of stem-like cancer cells (GSCs) that home to specialized perivascular niches. GSC interactions with their niche influence self-renewal, differentiation and drug resistance, although the pathways underlying these events remain largely unknown. Here, we report that the integrin αvβ8 and its latent transforming growth factor β1 (TGFβ1) protein ligand have central roles in promoting niche co-option and GBM initiation. αvβ8 integrin is highly expressed in GSCs and is essential for self-renewal and lineage commitment in vitro. Fractionation of β8high cells from freshly resected human GBM samples also reveals a requirement for this integrin in tumorigenesis in vivo. Whole-transcriptome sequencing reveals that αvβ8 integrin regulates tumor development, in part, by driving TGFβ1-induced DNA replication and mitotic checkpoint progression. Collectively, these data identify the αvβ8 integrin-TGFβ1 signaling axis as crucial for exploitation of the perivascular niche and identify potential therapeutic targets for inhibiting tumor growth and progression in patients with GBM.
