TP53家族基因TP73与肿瘤发生的研究进展

p73蛋白是p53蛋白家族的主要成员之一,其编码基因TP73与TP53基因高度同源.与p53蛋白类似,p73蛋白功能涉及细胞生命活动的各个方面;但又与p53不同,p73蛋白在机体正常的细胞活动和肿瘤的发生发展中不仅扮演着抑癌因子的角色,其功能的复杂性和重要性丝毫不亚于p53蛋白.肿瘤发生涉及多种细胞生物学过程,例如细胞...

Progress of TP53 Family Gene TP73 and Tumorigenesis

P73 protein is one of the main members of p53 protein family, and its coding gene TP73 is highly homologous to TP53 gene. On one hand, similar to p53, p73 protein is involved in all aspects of cell life. On the other hand, unlike the p53, not only p73 protein plays the role of tumor suppressor in normal cell activities and tumor development, but also the function of p73 protein is no less complex and important than that of p53 protein. Tumorigenesis involves a variety of cellular biological processes, such as apoptosis, autophagy, cell migration and cell metabolism. These normal cellular biological processes are tightly regulated by multiple cellular signaling pathways to maintain homeostasis. Once a carcinogenic abnormality occurs, it will eventually lead to tumorigenesis. Therefore, this paper mainly focuses on the important research results of p73 and tumorigenesis and its unique function different from p53 protein in recent years.
