功能基因组学提供的证据表明,人类基因组除了转录蛋白质编码基因外,还转录大量非编码基因,包括microRNAs和长非编码RNAs(LncRNAs)。与LncRNAs的其他成员相比,在LncRNAs组中有一些过去没有被关注的假基因。然而,越来越多的证据表明,假基因在多种细胞功能中起着重要的作用,而假基因的失调往往与包括癌症在内的各种人类疾病有关。与其他类型的lncRNA一样,假基因也可以作为基因表达的主要调节因子,因此,它们可以在肿瘤发生的各个方面发挥关键作用。在这篇综述中,我们讨论了假基因研究的最新进展,重点讨论了假基因如何通过不同的基因调控机制影响肿瘤的发生。鉴于与相应亲本基因的高度序列同源性,我们还讨论了假基因研究面临的挑战。
Functional genomics has provided evidence that the human genome transcribes a large number of non-coding genes in addition to protein-coding genes, including microRNAs and long non-coding RNAs (lncRNAs). Among the group of lncRNAs are pseudogenes that have not been paid attention in the past, compared to other members of lncRNAs. However, increasing evidence points the important role of pseudogenes in diverse cellular functions, and dysregulation of pseudogenes are often associated with various human diseases including cancer. Like other types of lncRNAs, pseudogenes can also function as master regulators for gene expression and thus, they can play a critical role in various aspects of tumorigenesis. In this review we discuss the latest developments in pseudogene research, focusing on how pseudogenes impact tumorigenesis through different gene regulation mechanisms. Given the high sequence homology with the corresponding parent genes, we also discuss challenges for pseudogene research.
