Disabled-2基因与肿瘤的相关研究

Research on the correlation of Disabled-2 gene and tumors

信号转导是一个十分精细、复杂的过程,参与细胞的增殖、分化、成熟和凋亡的每一步。在正常情况下人体组织中的Disabled-2蛋白(Dab2)参与细胞的信号转导使机体保持正常功能,而在有些情况下Dab2蛋白的缺失影响正常信号转导途径,从而细胞发生异型性变化、癌变。本文综述Dab2基因及其相关蛋白的结构、功能及与肿瘤发生机制,并对Dab2这个可能的抑癌基因作进一步探讨。

Signal transduction is a very fine and complicated process that indudes participation in the cell propagation, division, maturation and apoptosis.Under normal circumstance disabled-2( Dab2) in human tissues participates in the signal transduction of the cell in order to allow the body to keep normal functions,but under some circumstances the absence of Dab2 influences the normal signal transduction path,leding to atypical cell changes.and the generation of tumors.This paper is a review on the construction and function of Dab2 and its related gene as well as the relation of Dab2 and tumors generation.
