肿瘤干细胞(CSCs)是肿瘤细胞的一个亚群,被认为对肿瘤的维持、转移和治疗耐药起关键作用。因此,CSCs的前瞻性识别和靶向是开发新的治疗范例的优先事项。虽然包括CD133(Prominin-1)在内的细胞表面蛋白已经实现了对CSC的丰富,但目前CSC标记物在肿瘤维持中的作用尚不清楚。我们检测了患者标本中胶质母细胞瘤干细胞血管周围的微环境,以确定具有功能意义的浓缩标记物,并确定整合素α6为候选。整合素α6与传统的GSC标志物共表达,并在GSC中得到丰富。靶向GSCs中的整合素α6抑制自我更新、增殖和肿瘤形成能力。我们的结果为GSCs高水平表达整合素α-6提供了证据,它不仅可以作为一个丰富的标记,而且可以作为一种有前景的抗胶质母细胞瘤的治疗方法。
Cancer stem cells (CSCs) are a subpopulation of tumor cells suggested to be critical for tumor maintenance, metastasis, and therapeutic resistance. Prospective identification and targeting of CSCs are therefore priorities for the development of novel therapeutic paradigms. While CSC enrichment has been achieved with cell surface proteins including CD133 (Prominin-1), the roles of current CSC markers in tumor maintenance remain unclear. We examined the glioblastoma stem cell (GSC) perivascular microenvironment in patient specimens to identify enrichment markers with a functional significance and identified integrin α6 as a candidate. Integrin α6 is co-expressed with conventional GSC markers and enriches for GSCs. Targeting integrin α6 in GSCs inhibits self-renewal, proliferation, and tumor formation capacity. Our results provide evidence that GSCs express high levels of integrin α6, which can not only serve as an enrichment marker but also as a promising anti-glioblastoma therapy.
