MYC是癌症中最重要的癌基因之一。事实上,MYC在50%-60%的肿瘤中表达上调。MYC的过度表达可以通过多种机制实现,包括基因复制、染色体易位或导致MYC稳定性增加的体细胞突变。然而,最近的研究发现了许多组织特异性的MYC非编码增强子,它们在癌症中发挥了重要作用,强调了MYC的长范围转录调控是导致MYC过度激活的关键新机制,也是不久的将来新的治疗策略的潜在靶点。在这里,我们总结了参与MYC远程转录调控的区域和机制,强调了MYC增强子在正常生理发育和MYC驱动的癌症发生和发展中的相关性。
MYC is one of the most important oncogenes in cancer. Indeed, MYC is upregulated in 50–60% of all tumors. MYC overexpression can be achieved through a variety of mechanisms, including gene duplications, chromosomal translocations or somatic mutations leading to increased MYC stability. However, recent studies have identified numerous tissue-specific non-coding enhancers of MYC that play major roles in cancer, highlighting long-range transcriptional regulation of MYC as a critical novel mechanism leading to MYC hyperactivation and as a potential target for new therapeutic strategies in the near future. Here, we summarize the regions and mechanisms involved in the long-range transcriptional regulation of MYC, underscoring the relevance of MYC enhancers both in normal physiological development and in MYC-driven cancer initiation and progression.
