爱泼斯坦-巴尔病毒(Epstein-Barr Virus,EBV)与多种人类肿瘤相关,它以微小染色体形式存在于B淋巴细胞的核中,并通过尚未完全了解的机制诱导肿瘤发生。在这里,我们提出了一个大规模的EBV功能基因组分析。我们实验生成的核小体定位图和病毒蛋白结合数据与700多个公开可用的高通量测序数据集整合在一起,这些数据集用于定位到EBV基因组的人类淋巴母细胞系。我们发现,病毒裂解基因与细胞癌相关途径共表达,表明裂解周期可能在病毒介导的肿瘤发生中发挥意想不到的作用。病毒癌基因表达和染色体结构的宿主调控因子被鉴定和验证,揭示了B细胞特异性蛋白Pax5在病毒基因调控中的作用,以及粘附素复合体在调节高阶染色质结构中的作用。我们的发现提供了对肿瘤发生中潜伏的病毒持久性的更深入的理解,并为未来的探索建立了有价值的病毒基因组学资源。
Epstein-Barr Virus (EBV), which is associated with multiple human tumors, persists as a minichromosome in the nucleus of B-lymphocytes and induces malignancies through incompletely understood mechanisms. Here, we present a large-scale functional genomic analysis of EBV. Our experimentally generated nucleosome positioning maps and viral protein binding data were integrated with over 700 publicly available high-throughput sequencing data sets for human lymphoblastoid cell lines mapped to the EBV genome. We found that viral lytic genes are coexpressed with cellular cancer-associated pathways, suggesting that the lytic cycle may play an unexpected role in virus-mediated oncogenesis. Host regulators of viral oncogene expression and chromosome structure were identified and validated, revealing a role for the B-cell-specific protein Pax5 in viral gene regulation and the cohesin complex in regulating higher order chromatin structure. Our findings provide a deeper understanding of latent viral persistence in oncogenesis and establish a valuable viral genomics resource for future exploration.
