Myc蛋白是正常发育过程中动物生长的关键调节因子,其失调是人类恶性肿瘤的主要驱动因素之一。它们作为转录因子发挥作用,(在脊椎动物中)控制许多与生长和增殖相关的基因,并且在某些情况下有助于全局基因调控。 我们在果蝇组织培养细胞中结合染色质免疫沉淀测序(ChIP - seq)和RNA测序(RNAseq)方法,确定了一组核心的不到500个Myc靶基因,其主要功能在于控制核糖体生物发生。在这些基因中,我们发现非编码小核仁RNA(snoRNA)基因是一大类新的Myc靶标。所有检测的snoRNAs都受Myc影响,并且在果蝇和脊椎动物中,它们中的许多都受到Myc的直接转录激活。snoRNAs的缺失会损害正常发育过程中的生长,而它们的过表达会增加神经肿瘤模型中的肿瘤质量。 这项工作表明,Myc是小核仁核糖核蛋白(snoRNP)生物发生的主要调节因子。此外,结合最近关于snoRNA参与人类癌症的观察结果,它提出了一种可能性,即Myc的转化效应部分是由这类非编码转录本介导的。 本文的在线版本(doi:10.1186/s12915 - 015 - 0132 - 6)包含补充材料,授权用户可获取。
Myc proteins are essential regulators of animal growth during normal development, and their deregulation is one of the main driving factors of human malignancies. They function as transcription factors that (in vertebrates) control many growth- and proliferation-associated genes, and in some contexts contribute to global gene regulation. We combine chromatin immunoprecipitation-sequencing (ChIPseq) and RNAseq approaches in Drosophila tissue culture cells to identify a core set of less than 500 Myc target genes, whose salient function resides in the control of ribosome biogenesis. Among these genes we find the non-coding snoRNA genes as a large novel class of Myc targets. All assayed snoRNAs are affected by Myc, and many of them are subject to direct transcriptional activation by Myc, both in Drosophila and in vertebrates. The loss of snoRNAs impairs growth during normal development, whereas their overexpression increases tumor mass in a model for neuronal tumors. This work shows that Myc acts as a master regulator of snoRNP biogenesis. In addition, in combination with recent observations of snoRNA involvement in human cancer, it raises the possibility that Myc’s transforming effects are partially mediated by this class of non-coding transcripts.
