Neuroblastoma (NB), a pediatric malignancy of the peripheral nervous system, is characterized by epigenetic and transcriptional (EP-TF) anomalies. This study aimed to develop an EP-TF clinical prognostic model for NB using CRISPR-Cas9 knockout screening. An integrative analysis was conducted using CRISPR-Cas9 screening and with public NB datasets to identify 35 EP-TF genes that exhibited the highest expression in NB and were highly dependent on cancer viability. After univariate analysis, 27 of these 35 genes were included in the least absolute shrinkage and selection operator screen. We established and biologically validated a prognostic EP-TF model encompassing and across diverse NB cohorts. MYCN serves a potential upstream regulator of EP-TF genes. The high-risk subtype exhibited traits associated with the malignant cell cycle, MYCN-linked signaling and chromatin remodeling, all of which are correlated with poor prognosis and immunosuppression. MEK inhibitors have emerged as promising therapeutic agents for targeting most EP-TF risk genes in NB. Our novel prognostic model shows significant potential for predicting and evaluating the overall survival of NB patients, offering insights into therapeutic targets.
神经母细胞瘤(NB)是一种小儿外周神经系统恶性肿瘤,其特征为表观遗传和转录(EP-TF)异常。本研究旨在利用CRISPR-Cas9基因敲除筛选开发一种用于NB的EP-TF临床预后模型。使用CRISPR-Cas9筛选并结合公开的NB数据集进行综合分析,以鉴定出35个在NB中表达最高且对癌症生存力高度依赖的EP-TF基因。单变量分析后,这35个基因中的27个被纳入最小绝对收缩和选择算子筛选。我们建立并通过生物学验证了一个涵盖不同NB队列的预后EP-TF模型。MYCN是EP-TF基因潜在的上游调节因子。高危亚型表现出与恶性细胞周期、MYCN相关信号传导和染色质重塑相关的特征,所有这些都与预后不良和免疫抑制相关。MEK抑制剂已成为靶向NB中大多数EP-TF风险基因的有前景的治疗药物。我们的新型预后模型在预测和评估NB患者总生存方面显示出巨大潜力,为治疗靶点提供了见解。
