基本螺旋-环-螺旋蛋白Myc是一种著名的转录因子,控制着细胞生理的不同方面,共同允许体细胞高效增殖。这种能力,再加上它在大多数人类癌症中表达失控的观察,表明Myc可能是一个很好的治疗靶点。然而,Myc生物学的几个方面仍然令人费解:致癌Myc和生理性Myc之间的主要区别是什么?致癌Myc如何避开进化提供的内在肿瘤监视途径?如果Myc的抑制甚至是可能的,会对正常增殖组织的动态平衡和癌细胞的命运产生什么后果?在这里,我们总结了解决这些问题的最新工作。
The basic helix-loop-helix protein Myc is a renowned transcription factor controlling disparate aspects of cell physiology that, together, allow efficient proliferation of somatic cells. This ability, together with the observation that its deregulated expression occurs in the majority of human cancers, suggests that Myc could be a good therapeutic target. However, several aspects of Myc biology remain elusive: what is the major difference between oncogenic and physiological Myc? How does oncogenic Myc evade the intrinsic tumor surveillance pathways provided by evolution? If Myc inhibition were even possible, what would be the consequences for the homeostasis of normal proliferating tissues versus the fate of cancer cells? Here we summarize the latest works addressing these issues.
