转录因子 E1AF 在神经元发育和肿瘤转移中发挥着关键作用,并受到许多信号级联的调节,包括丝裂原激活的蛋白激酶途径。积累的证据表明,E1AF 可能有助于细胞响应环境因素而存活。在这里,我们提供了细胞周期和凋亡调节因子 E2F1 在转录水平诱导 E1AF 表达的证据。依托泊苷造成的 DNA 损伤导致 E2F1 依赖性诱导转录水平的 E1AF 表达。此外,E1AF RNAi 破坏 E1AF 表达可减少 E2F1 诱导的依托泊苷响应的细胞凋亡。因此,我们得出结论,E1AF 的激活为 E2F1 提供了一种诱导细胞凋亡以响应 DNA 损伤的方法。
Transcription factor E1AF plays critical roles in neuronal development and tumour metastasis and is regulated by a number of signalling cascades, including the mitogen-activated protein kinase pathways. Accumulated evidence indicted that E1AF might contribute to cell survival in response to environment factors. Here, we provided evidence the cell cycle and apoptosis regulator E2F1 induces E1AF expression at the transcriptional level. DNA damage by etoposide causes E2F1-dependent induction of E1AF expression at transcriptional level. Furthermore, disruption of E1AF expression by E1AF RNAi decreased E2F1-induced apoptosis in response to etoposide. Thus, we conclude that activation of E1AF provides a means for E2F1 to induce cell apoptosis in response to DNA damage.
