Research progress on the characterization of structural variants in neuroblastoma genome
-
摘要: 神经母细胞瘤(neuroblastoma,NB)是起源于神经嵴细胞的儿童胚胎恶性肿瘤,表现为较强的生物学和临床异质性。基因组测序研究显示,NB具有较低的突变负荷和频发突变。NB表现为携带较多的基因组结构性变异,是其发生、发展的重要驱动因素。临床上已将MYCN扩增和11q缺失等基因组结构性变异纳入风险分组中,但目前对于NB基因组结构性变异的了解与NB的生物学、临床复杂性仍存在差距。高通量基因组学技术的发展推动了研究者对NB基因组特征尤其是结构性变异特征有了更加全面的认识,为探索NB发生、发展机制以及更加精细的风险分层提供了数据基础。本文就近年来NB的基因组结构性变异特征研究进展进行综述。Abstract: Neuroblastoma (NB) is an embryonic malignancy arising from the neural crest cells of the sympathetic nervous system. It exhibits a high degree of biological and clinical heterogeneity. Genome sequencing studies have shown that NB has a low mutational load and few recurrent mutations. However, NB exhibits a high number of genomic structural variants, which are important drivers of tumorigenesis and progression. Genomic structural variants, such as MYCN amplification and 11q deletion, have been used as biomarkers for risk stratification in clinical practice. Nevertheless, a gap still exists between the understanding of genomic structural variants in NB and its biological and clinical heterogeneity. The development of high-throughput genomics technologies has promoted a more comprehensive understanding of the genomic features of NB, especially its structural variants. Further understanding of the involvement of these genomic characteristics in tumorigenesis and progression will help clarify risk stratification. In this paper, we review the current research on characterization of genomic structural variant in NB.
