不受干扰的细胞周期的DNA合成S期是一个封闭的系统,与外部生长因子对G1的调节相比。E2F家族通过转录脱氧核苷酸三磷酸(DNTP)和脱氧核糖核酸合成所需的基因,在S期提供内部控制。此外,E2F-1的过度表达激活了程序性细胞死亡(凋亡),这是致癌细胞异常生长的保护信号。因此,控制E2F-1的机制至关重要。假设脱氧胸苷三磷酸(DTTP)变构反馈控制E2F-1调节DNA合成和细胞凋亡。这可能在E2F-1的产生或其降解时起作用。
The DNA synthetic S phase of the unperturbed cell cycle is a closed system, as compared to regulation of G1 by external growth factors. The E2F family provides internal control in S phase by transcribing genes required for deoxynucleotide triphosphate (dNTP) and DNA synthesis. Furthermore, over expression of E2F-1 activates programmed cell death (apoptosis), a safeguarding signal of aberrant growth of cells that have become carcinogenic. Mechanisms for control of E2F-1 are thus essential. The hypothesis is proposed that deoxythymidine triphosphate (dTTP) allosterically feedback controls E2F-1 to regulate both DNA synthesis and apoptosis. This may act either upon production of E2F-1 or its degradation.
