p53蛋白是一种防止肿瘤发展的转录因子。在自发性和遗传性癌症中,TP53基因的DNA结合结构域中存在许多不同的错义突变,这些错义突变有助于肿瘤形成。这些突变在突变型p53蛋白的转录能力中产生广泛的分布,在许多不同的组织类型中形成癌症的效率具有超过4个对数的差异。这些遗传性和自发性TP53突变产生的蛋白质与p53功能的遗传和表观遗传细胞修饰剂及其遗传多态性相互作用,从而在个体患者中产生大量不同的表型。本文综述了这些变量,并讨论了TP 53基因改变的组合如何与遗传多态性、表观遗传改变和环境因素相互作用,从而开始预测和改变患者的结局,并为新的治疗机会提供更好的理解。
The p53 protein is a transcription factor that prevents tumors from developing. In spontaneous and inherited cancers there are many different missense mutations in the DNA binding domain of the TP53 gene that contributes to tumor formation. These mutations produce a wide distribution in the transcriptional capabilities of the mutant p53 proteins with over four logs differences in the efficiencies of forming cancers in many diverse tissue types. These inherited and spontaneous TP53 mutations produce proteins that interact with both genetic and epigenetic cellular modifiers of p53 function and their inherited polymorphisms to produce a large number of diverse phenotypes in individual patients. This manuscript reviews these variables and discusses how the combinations of TP53 genetic alterations interact with genetic polymorphisms, epigenetic alterations, and environmental factors to begin predicting and modifying patient outcomes and provide a better understanding for new therapeutic opportunities.
