生化/生理作用

(S)-(+)-喜树碱和DNA拓扑异构酶I复合体不可逆地结合,抑制拓扑异构酶I剪切后DNA重组,将酶和DNA以共价键形式锁住。酶复合体被泛素化,被26S蛋白酶破坏,耗尽细胞内拓扑异构酶I。该酶在低剂量下在S期阻碍细胞周期,在大多数正常和肿瘤细胞中通过依赖细胞周期和不依赖细胞周期的过程诱发细胞凋亡。

We presents an article on Autophagy in Cancer Promotes Therapeutic Resistance

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
