Telomeres play an important role in cellular aging and cancer. Human telomeric DNA and RNA G-rich sequences are capable of forming a four-stranded structure, known as the G-quadruplex. Such a structure might be important for telomere biology and a good target for drug design. This minireview describes the structural diversity or conservation of DNA and RNA human telomeric G-quadruplexes, discusses structural views on targeting these G-quadruplexes and presents some future challenges for structural studies.
端粒在细胞衰老和癌症中起着重要作用。人类端粒 DNA 和 RNA G-丰富序列能够形成一种四链结构,称为 G-四链体。这种结构可能对端粒生物学很重要,也是药物设计的一个很好的靶点。这篇综述描述了 DNA 和 RNA 人类端粒 G-四链体的结构多样性或保守性,讨论了针对这些 G-四链体的结构观点,并提出了一些未来结构研究的挑战。
