PAK2的生物学特性及其与肿瘤关系的研究进展

The research progress on the biological characteristics of PAK2 and its correlation with tumor

p21激活激酶2(PAK2)因参与一系列的细胞内生物学活动,对肿瘤研究具有一定的价值,但目前对于其与肿瘤关系的研究相对较少。PAK2可被多种上游信号特别是G蛋白Rho家族的Rac和Cdc42激活,参与多种重要的信号通路及细胞功能的调控。PAK2在多种肿瘤中异常表达后可参与细胞骨架重构、细胞运动、凋亡、信号转导、基因转录翻译及血管生成等,在肿瘤的发生、发展中起重要作用。因此,开展PAK2的相关研究和针对其的靶向治疗可能对肿瘤防治提供新的视角。

The activation of p21 kinase 2 （PAK2） has a certain value in cancer research, since its participation in a series of intracellular biological activities. There is a relatively little research on its relationship with the development of tumors. PAK2 can be activated by a variety of upstream signals, especially small G protein Rho family of Rac and Cdc42, and it participates in a variety of important signaling pathways and cell function regulation. Abnormal expression of PAK 2 has been reported in various tumors, which involves in cytoskeletal remodeling, cell motility, apoptosis, signal transduction, gene transcription, translation and angiogenesis. Therefore, PAK2 plays an important role in tumor occurrence and development. The study on PAK2 and the targeting therapy for anti-PAK2 provides a new sight on the treatment and prevention of tumor.
