转录后基因调控是一种快速有效的调节细胞蛋白质组以适应环境变化的过程。rna结合蛋白(rbp)是mRNA加工和翻译的主要调控因子,在癌症中经常异常表达。除了被充分研究的转录因子外,rbp在肿瘤发展中也扮演着重要的角色。rbp及其mRNA靶标形成了一个复杂的网络,在肿瘤发生中起着至关重要的作用。本文描述了rbp影响已知癌基因表达的机制,重点阐述了rbp在转录后控制癌症发展中的多功能性。rbp在进化中很早就出现了,在更复杂的生物体中产生了新的rna结合结构域和它们的组合。rbp及其mRNA靶点的鉴定及其作用机制为癌症治疗提供了新的潜在靶点。
Posttranscriptional gene regulation is a rapid and efficient process to adjust the proteome of a cell to a changing environment. RNA-binding proteins (RBPs) are the master regulators of mRNA processing and translation and are often aberrantly expressed in cancer. In addition to well-studied transcription factors, RBPs are emerging as fundamental players in tumor development. RBPs and their mRNA targets form a complex network that plays a crucial role in tumorigenesis. This paper describes mechanisms by which RBPs influence the expression of well-known oncogenes, focusing on precise examples that illustrate the versatility of RBPs in posttranscriptional control of cancer development. RBPs appeared very early in evolution, and new RNA-binding domains and combinations of them were generated in more complex organisms. The identification of RBPs, their mRNA targets, and their mechanism of action have provided novel potential targets for cancer therapy.
