摘要:G4 DNA是一种非典型的DNA结构,由鸟嘌呤碱基之间的碱基配对组成的堆叠的G-四分之一阵列。 G4 DNA的形成需要在DNA链中进行一群鸟嘌呤运行。即使这种非凡的DNA结构的化学作用已经进行了数十年的研究,但支持G4 DNA的生物学相关性的证据才开始出现并指出非常重要和保守的生物学功能。这篇综述将特别关注转录和G4 DNA之间的相互作用,并讨论两个替代方案但相互联系的观点。审查的第一部分将描述证据证明DNA结构构象转移可能是基因表达的非遗传或表观遗传调节剂的另一层,从而证实了细胞命运的重要决定因素。第二部分将描述最近的遗传研究表明,那些含有G4 DNA形成鸟嘌呤的序列的基因组基因元基因组基因组是基因组不稳定性的潜在热点,而转录的水平和方向对于与这些序列相关的基因组不稳定性的物质化至关重要。
Abstract: G4 DNA is a non-canonical DNA structure consisting of a stacked array of G-quartets held together by base pairing between guanine bases. The formation of G4 DNA requires a cluster of guanine-runs within a strand of DNA. Even though the chemistry of this remarkable DNA structure has been under investigation for decades, evidence supporting the biological relevance of G4 DNA has only begun to emerge and point to very important and conserved biological functions. This review will specifically focus on the interplay between transcription and G4 DNA and discuss two alternative but interconnected perspectives. The first part of the review will describe the evidence substantiating the intriguing idea that a shift in DNA structural conformation could be another layer of non-genetic or epigenetic regulator of gene expression and thereby an important determinant of cell fate. The second part will describe the recent genetic studies showing that those genomic loci containing G4 DNA-forming guanine-rich sequences are potential hotspots of genome instability and that the level and orientation of transcription is critical in the materialization of genome instability associated with these sequences.
