中文摘要
尽管在研究和临床研究方面做出了重大努力,但患有最常见疾病和侵略性疾病的患者的存活率仍然很高。
在过去的25年里,原发性脑肿瘤和胶质母细胞瘤(GBM)的发病率只有轻微的变化,而且是唯一的变化。
大约15个月。因此,现在迫切需要新的分子药物靶点、新概念和新技术。
近年来,微核糖核酸(MiRNA)作为一种新的治疗方法和很有前途的一类药物应运而生。
我们对致癌基因miRNAs的研究使我们开始关注这一问题。
在miR-10b上,一种独特的miRNA基因在所有的GBM亚型中高度表达,但在正常的神经胶质细胞中缺失。
大脑。;-10b控制着恶性脑胶质瘤的生长速度;此外,它似乎对肿瘤的生存能力至关重要。
异质性脑胶质瘤细胞和脑胶质瘤-启动干细胞移植(GSC)。因此,对MmiR-10b基因的抑制或丢失是非常重要的。
对脑胶质瘤来说是致命的。我们的初步研究数据表明,在几种针对脑胶质瘤的治疗方法中,CRISPR--Cas9--
基于miR-10b的基因消融可以更有效地根除小鼠脑内已建立的GGBM基因。更重要的是,
尽管MmiR-10b在BGBM中具有重要的基础和成瘾作用,但它仍具有潜在的潜在靶向性,即分子靶向。
人们对MmiR-2010亿欧元活动的潜在机制了解不深,而且很大程度上是非常规的。这是全球总体目标。
因此,这项提案包括两个方面:第一,继续调查潜在的GGBM的分子生物学机制。
对MmiR-10b的依赖,以及第二,将开发基于MmiR-11b基因的高效的治疗药物策略。
编辑。这是由MmiR-10b调控的信号转导通路的说明,以及为其提供的新方法的发展趋势。
靶向治疗药物将对基础疾病和临床治疗、神经肿瘤学、癌症和癌症等产生重大影响。
一般而言,针对1个特定目标的新工作计划将不会描述内源性的MmiR-10b和互动组的特征,并将确定。
主要针对脑胶质瘤和脑胶质瘤干细胞。目前正在使用多种功能分析的有效组合,以明确-
CLIP技术和基于CRISPR-Cas9的技术,以及其他定量蛋白质组学,我们将不会从生理上定义它们。
重要的蛋白质编码基因和非编码基因的靶点是潜在的GbM成瘾症。具体的目标是2%。
调查基于CRISPR-Cas9的JmiR-10b基因编辑功能对人体生长发育和原位肿瘤侵袭率的影响。
胶质瘤。通过使用人类GSC来源的异种移植瘤和具有免疫活性的GL261来建立原位GGBM和小鼠移植模型。
除了原代和正常的神经胶质细胞外,我们还将检查各种基因工程的有效性和安全性。
CRISPR-CAS9系统和病毒式消融车辆需要在GGBM中进行目标为11miR-10b的消融手术。我们将进一步进行比较。
基于反义寡核苷酸的基因靶向效应和基于靶向基因的基因编辑策略。
这项工作承诺将对恶性脑胶质瘤的肿瘤生物学研究产生重大和新的洞察力,这可能会导致研究。
新的、非常见的、有效的和有效的治疗方法的开发适用于所有的GBM亚型。
英文摘要
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.
