Recent molecular studies have expanded the biological contexts in which topoisomerase II (TOP2) has crucial functions, including DNA replication, transcription and chromosome segregation. Although the biological functions of TOP2 are important for ensuring genomic integrity, the ability to interfere with TOP2 and generate enzyme-mediated DNA damage is an effective strategy for cancer chemotherapy. The molecular tools that have allowed an understanding of the biological functions of TOP2 are also being applied to understanding the details of drug action. These studies promise refined targeting of TOP2 as an effective anticancer strategy.
最近的分子研究拓展了拓扑异构酶II(TOP2)发挥关键作用的生物学背景,包括DNA复制、转录和染色体分离。尽管TOP2的生物学功能对于确保基因组完整性很重要,但干扰TOP2并产生酶介导的DNA损伤的能力是癌症化疗的一种有效策略。有助于理解TOP2生物学功能的分子工具也正被用于了解药物作用的细节。这些研究有望实现对TOP2的精准靶向,作为一种有效的抗癌策略。
