Studies involving miRNAs have opened discussions about their broad participation in viral infections. Regarding the or Epstein-Barr virus (EBV), miRNAs are important regulators of viral and cellular gene expression during the infectious process, promoting viral persistence and, in some cases, oncogenic processes. We identified 55 miRNAs of EBV type 2 and inferred the viral mRNA target to self-regulate. This data indicate that gene self-repression is an important strategy for maintenance of the viral latent phase. In addition, a protein network was constructed to establish essential proteins in the self-regulation process. We found ten proteins that work as hubs, highlighting BTRF1 and BSRF1 as the most important proteins in the network. These results open a new way to understand the infection by EBV type 2, where viral genes can be targeted for avoiding oncogenic processes, as well as new therapies to suppress and combat the persistent viral infection.
涉及微小RNA(miRNA)的研究引发了关于它们广泛参与病毒感染的讨论。关于EB病毒(EBV),miRNA是感染过程中病毒和细胞基因表达的重要调节因子,促进病毒持续性感染,在某些情况下还促进致癌过程。我们鉴定出了2型EBV的55种miRNA,并推断出病毒mRNA靶点以进行自我调节。这些数据表明基因自我抑制是维持病毒潜伏期的重要策略。此外,构建了一个蛋白质网络以确定自我调节过程中的关键蛋白质。我们发现有十种蛋白质起枢纽作用,其中BTRF1和BSRF1是该网络中最重要的蛋白质。这些结果为理解2型EBV感染开辟了一条新途径,在此过程中,病毒基因可成为避免致癌过程的靶点,同时也为抑制和对抗持续性病毒感染提供了新的治疗方法。
