It is imperative to identify the mechanisms that confer stemness to the cancer cells for more effective targeting. Moreover, there are not many studies on the link between stemness characteristics and the immune response in tumours. Therefore, in the current study involving GBM, we started with the study of BIRC5 (one of the rare genes differentially expressed in normal and cancer cells) and CXCR4 (gene involved in the survival and proliferation of CSCs). Together, these genes have not been systematically explored. We used a set of 27 promoter methylated regions in GBM. Our analysis showed that four genes corresponding to these regions, namely EOMES, BDNF, HLA-A, and PECAM1, were involved with BIRC5 and CXCR4. Interestingly, we found EOMES to be very significantly involved in stemness and immunology and it was positively correlated to CXCR4. Additionally, BDNF, which was significant in methylation, was negatively correlated to BIRC5.
确定赋予癌细胞干性的机制对于更有效的靶向治疗至关重要。此外,关于干性特征与肿瘤中免疫反应之间的联系的研究并不多。因此,在目前涉及 GBM 的研究中,我们从研究 BIRC5(在正常和癌细胞中差异表达的稀有基因之一)和 CXCR4(参与 CSCs 存活和增殖的基因)开始。这两个基因尚未被系统地探索。我们使用了一组 27 个在 GBM 中启动子甲基化的区域。我们的分析表明,对应于这些区域的四个基因,即 EOMES、BDNF、HLA-A 和 PECAM1,与 BIRC5 和 CXCR4 有关。有趣的是,我们发现 EOMES 与干性和免疫学密切相关,并且与 CXCR4 呈正相关。此外,BDNF 在甲基化中具有显著意义,与 BIRC5 呈负相关。
