爱泼斯坦巴尔病毒(EB病毒)是1964年发现的第一种与人类癌症相关的病毒,在世界人口中普遍存在。现在已经确定,EBV有助于淋巴和上皮细胞起源的多种人类癌症的发展和进展。EBV编码的miRNA在肿瘤增殖、血管生成、免疫逃逸、组织侵袭和转移中起重要作用。最近,已经发现EBV miRNA从细胞外囊泡(EV)中的感染癌细胞释放,并调节存在于肿瘤微环境中的邻近未感染细胞中的基因表达,并且可能在远端位点。由于EV在许多生物液体中丰富,EBV修饰的EV中存在的病毒和细胞miRNA可作为癌症诊断和预后的非侵袭性标志物。在这篇综述中,我们讨论了EV分离和miRNA检测的最新进展,并提供了一个完整的工作流程,从血浆中纯化EV和深度测序的生物标志物发现。
Epstein Barr-virus (EBV) was the first virus identified to be associated with human cancer in 1964 and is found ubiquitously throughout the world’s population. It is now established that EBV contributes to the development and progression of multiple human cancers of both lymphoid and epithelial cell origins. EBV encoded miRNAs play an important role in tumor proliferation, angiogenesis, immune escape, tissue invasion, and metastasis. Recently, EBV miRNAs have been found to be released from infected cancer cells in extracellular vesicles (EVs) and regulate gene expression in neighboring uninfected cells present in the tumor microenvironment and possibly at distal sites. As EVs are abundant in many biological fluids, the viral and cellular miRNAs present within EBV-modified EVs may serve as noninvasion markers for cancer diagnosis and prognosis. In this review, we discuss recent advances in EV isolation and miRNA detection, and provide a complete workflow for EV purification from plasma and deep-sequencing for biomarker discovery.
