TOP2A

TOP2A,即DNA拓扑异构酶IIα,别名DNA topoisomerase IIα。它是一种由TOP2A基因编码的酶,广泛存在于真核细胞中,主要参与DNA复制、修复和转录过程中的DNA超螺旋的调控。TOP2A的作用机制是通过切割和重新连接DNA的一条链,消除DNA超螺旋和缠结,从而调节DNA的拓扑结构。TOP2A在细胞周期中发挥作用,特别是在S期和G2期,对DNA的合成和修复至关重要。TOP2A在生物学上的意义非常广泛,它不仅参与了DNA的正常代谢过程,而且与多种疾病的发生发展密切相关。TOP2A的异常表达或功能失调与某些癌症的发生有关,例如前列腺癌、乳腺癌和膀胱癌等。TOP2A也是一些抗癌药物,如蒽环类抗生素和喜树碱类化合物的靶点,这些药物通过抑制TOP2A的活性来阻止肿瘤细胞的增殖。因此,TOP2A是癌症治疗中的一个潜在靶点,针对TOP2A的药物开发和研究对于癌症治疗具有重要意义 。

CSB-RA696677A0HU

IHC image of CSB-RA696677A0HU diluted at 1:100 and staining in paraffin-embedded human lung cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
