摘要
背景:多形性胶质母细胞瘤是最常见、最致命的脑恶性肿瘤。最近的证据表明,肿瘤内存在干细胞,具有较高的自我更新能力、对化疗的抵抗力和侵袭/迁移潜能,这与GBM预后不良有关。GSC侵袭性似乎与肿瘤发生和转移的一个重要过程有关,即上皮间充质转移(EMT),EMT负责GSCs的多种生化改变和更多间充质表型的获取,从而增强GSC的迁移、侵袭性和抗凋亡能力。目的:由于嘌呤与自身受体相互作用,在GBM和衍生细胞中具有抗肿瘤作用,因此,我们试图研究这些化合物对EMT相关基因/激活剂和/或信号通路上的肿瘤细胞迁移/侵袭的抑制作用。方法:查阅相关文献中与目的相关的文章。结果:研究嘌呤对GSCs EMT信号通路/标记物活性的研究尚不多见,而文献较多。结论:考虑到EMT在GBM侵袭性中的意义和嘌呤在此过程中的潜在参与,我们认为这方面的进一步研究为控制GBM侵袭/复发开辟了一条新的治疗途径。

摘要: Background: Glioblastoma Multiforme (GBM) is the most common and lethal brain malignancy. Recent evidence suggests that the presence of stem-like cells (GSCs) inside the tumor with high self-renewal, resistance to chemotherapy and invasiveness/migration potential is associated with poor GBM prognosis. GSC aggressiveness seems to be linked to an important process involved in tumorigenesis and cancer metastasis called Epithelial-to-Mesenchymal Transition (EMT), which is responsible for several biochemical changes and the acquisition of a more mesenchymal phenotype by GSCs, that enhance their migration, invasiveness and resistance to apoptosis.
Objective: Since previous reports demonstrated that purines, interacting with their own receptors, exerted anti-tumor effects in GBM and derived cells, we tried to investigate the ability of these compounds to reduce tumor cell migration/invasion acting on EMT-associated genes/activators and/or signal pathways.
Methods: Search in the literature of relevant articles related to the objective.
Results: Papers examining the activity of purines on EMT signaling pathways/markers in GSCs are still few whereas literature is more abundant as for other kinds of tumors.
Conclusion: Considering the significance of EMT in GBM aggressiveness and the promising involvement of purines in this process, we think that further research in this regard may open the way towards a new therapeutic approach for the control of GBM invasiveness/recurrence.
