摘要: 不稳定编码区(CRD)是cmyc基因的影响因素之一。不稳定编码区结合蛋白(CRDBP)与CRD结合可使CRD免受核酸内切酶攻击,阻止cmyc mRNA快速降解,增加cmyc蛋白含量。β转导重复相容蛋白(βTrCP)可对多个信号通路及细胞周期进行调控,影响细胞生长、分化、凋亡及肿瘤形成。CRDBP高表达进而上调βTrCP,与结直肠癌的发生发展、转移侵袭等密切相关。

Abstract: Coding region instability determinant (CRD) is one of the influence factors of oncogene cmyc. Coding region instability determinantbinding protein (CRDBP) can connect with CRD in order to protect CRD from nuclease attack, prevent rapid degradation of cmyc mRNA, and increase cmyc protein content. Betatransducin repeatscontaining protein (βTrCP) can affect cell growth, differentiation, apoptosis and oncogenesis by regulating multiple signaling pathways and cell cycle. The overexpression of CRDBP can upregulate the expression of βTrCP and both of them play important roles in the tumorigenesis, progression, metastasis and invasion of colorectal cancer.
