项目摘要
Despite significant research and clinical efforts, survival of patients with most common and aggressive
primary brain tumor glioblastoma (GBM) has only marginally changed over the past 25 years and is only
around fifteen months. There is, therefore, an urgent need for new molecular targets, concepts and
approaches to treating GBM. In the recent years, microRNA (miRNA) emerged as a new and promising class
of targetable molecules that holds great potential in oncology. Our work on oncogenic miRNAs led us to focus
on miR-10b, a unique miRNA highly expressed in all GBM subtypes but absent in normal neuroglial cells of
the brain. miR-10b controls the growth of malignant gliomas;; moreover, it appears essential for viability of
heterogeneous glioma cells and glioma-initiating stem cells (GSC). Inhibition or loss of miR-10b is, therefore,
lethal for glioma. Our preliminary data suggests that, among several targeting approaches, CRISPR-Cas9-
based miR-10b gene ablation eradicates established intracranial GBM in mice more effectively. Importantly,
despite the fundamental addictive role of miR-10b in GBM, and the potential of its targeting, molecular
mechanisms underlying miR-10b activity are poorly understood and largely unconventional. The overall goal
of this proposal is, therefore, two-fold: first, to investigate molecular mechanisms underlying GBM
dependence on miR-10b, and second, develop efficient therapeutic strategies based on miR-10b gene
editing. Elucidation of the signaling pathways regulated by miR-10b, and development of approaches for its
therapeutic targeting will have an impact on both basic and clinical neuro-oncology, and cancer more
generally. The work for Specific Aim 1 will characterize endogenous miR-10b interactome and identify
principal miR-10b targets in glioma and glioma stem cells. Using a combination of functional assays, CLEAR-
CLIP and CRISPR-Cas9-based technologies, and quantitative proteomics, we will define physiologically
important protein-coding and non-coding targets underlying GBM addiction to miR-10b. Specific Aim 2 will
investigate the effects of CRISPR-Cas9-based miR-10b gene editing on growth and invasion of orthotopic
glioma. Using human GSC-derived xenografts and immunocompetent GL261 orthotopic GBM mouse models,
as well as primary normal neuroglial cells, we will examine efficacy and safety of various engineered
CRISPR-Cas9 systems and viral vehicles for targeted miR-10b ablation in GBM. We will further compare off-
target effects of antisense oligonucleotide based and gene editing based targeting strategies. The proposed
work promises to yield significant new insights into the biology of malignant gliomas and may lead to the
development of new, common, and potent therapies for all GBM subtypes.
尽管进行了大量的研究和临床努力,但最常见和侵袭性的患者的存活率
原发性脑肿瘤胶质母细胞瘤 (GBM) 在过去 25 年中仅发生了微小变化,并且仅
因此,迫切需要新的分子靶标、概念和方法。
近年来,microRNA (miRNA) 成为一种新的、有前途的类别。
在肿瘤学方面具有巨大潜力的靶向分子的研究使我们将重点放在致癌 miRNA 上。
miR-10b 是一种独特的 miRNA,在所有 GBM 亚型中高表达,但在正常神经胶质细胞中不存在
miR-10b 控制恶性神经胶质瘤的生长;此外,它对于神经胶质瘤的生存至关重要。
因此,miR-10b 的抑制或丧失是异质性神经胶质瘤细胞和神经胶质瘤起始干细胞(GSC)的影响。
我们的初步数据表明,在多种靶向方法中,CRISPR-Cas9-
基于 miR-10b 基因的消融可以更有效地根除小鼠颅内已形成的 GBM。
尽管 miR-10b 在 GBM 中具有基本的成瘾作用及其靶向潜力,但分子
miR-10b 活性背后的机制人们知之甚少,而且很大程度上是非常规的。
因此,该提议有两个方面:第一,研究 GBM 背后的分子机制
对miR-10b的依赖,二是基于miR-10b基因制定高效的治疗策略
阐明 miR-10b 调节的信号通路,并开发其方法。
治疗靶向将对基础和临床神经肿瘤学以及癌症产生更多影响
一般来说,特定目标 1 的工作将表征内源 miR-10b 相互作用组并进行鉴定。
神经胶质瘤和神经胶质瘤干细胞中的主要 miR-10b 靶标使用功能分析的组合,CLEAR-
基于 CLIP 和 CRISPR-Cas9 的技术以及蛋白质组学,我们从生理学角度定量定义
GBM 对 miR-10b 成瘾的重要蛋白质编码和非编码靶标将被确定。
研究基于 CRISPR-Cas9 的 miR-10b 基因编辑对原位生长和侵袭的影响
使用人类 GSC 衍生的异种移植物和免疫活性 GL261 原位 GBM 小鼠模型,
以及原代正常神经胶质细胞,我们将检查各种工程化的功效和安全性
我们将进一步比较用于 GBM 中靶向 miR-10b 消融的 CRISPR-Cas9 系统和病毒载体。
所提出的基于反义寡核苷酸和基于基因编辑的靶向策略的靶向效果。
这项工作有望对恶性神经胶质瘤的生物学产生重要的新见解,并可能导致
为所有 GBM 亚型开发新的、常见的和有效的疗法。
