Elucidate genetic regulation of GBM differentiation

摘要胶质母细胞瘤是最常见和最具侵袭性的原发性脑癌，其发病率极低。 预后。迫切需要改进这种疾病治疗的新方法。积累 有证据表明，这种疾病缺乏有效的治疗方法是因为现有的治疗方案不能 有效消除胶质母细胞瘤干细胞(GSCs)，这是GBM发展的根源。一种很有希望的方法 消除GSC就是诱导GSC分化。不幸的是，辨证治疗的发展 由于我们对GSC分化的生物学认识不足，限制了GBM的发展。在此应用程序中， 我们建议表征GSC分化的遗传调控，并验证可以靶向的基因 进行有效的基底膜分化治疗。作为初步工作，我们确定了一组基因，它们有可能 通过RNAi筛选和单细胞联合作用调节GSC向特定谱系的分化 RNA测序法。在本应用中，我们将表征Lead GSC分化调控 Aim 1中的候选基因，并确定所选基因对GSC分化的治疗潜力 目标2的治疗。该项目的成功将导致发现新的GSC分化调节剂， 可能成为改善GBM治疗的潜在靶点。

Glioblastoma (GBM) is the most common and aggressive form of primary brain cancer with extremely poor prognosis. New approaches for improved treatment of this disease are desperately needed. Accumulating evidence suggests that the lack of effective treatment for this disease is because the existing regimens cannot effectively eliminate glioblastoma stem cells (GSCs), the root of GBM development. One promising approach to eliminating GSCs is to induce GSC differentiation. Unfortunately, the development of differentiation therapy for GBM has been limited by our poor understanding of the biology of GSC differentiation. In this application, we propose to characterize genetic regulation of GSC differentiation and validate genes that can be targeted for effective GBM differentiation therapy. As preliminary work, we identified a group of genes, which potentially regulate GSC differentiation toward specific lineages through a combination of RNAi screening and single-cell RNA sequencing approach. In this application, we will characterize lead GSC differentiation regulatory candidate genes in Aim 1, and to determine the therapeutic potential of selected genes for GSC differentiation therapy in Aim 2. Success of this project will lead to identification of novel GSC differentiation regulators that can be potentially targeted for improved treatment of GBM.
