细胞周期蛋白依赖性激酶5(Cyclin-dependent kinase 5,CDK 5)是细胞周期蛋白依赖性激酶家族的一个非典型成员,在神经系统中起着重要作用。最近的研究表明,CDK 5也与肿瘤有关。然而,很少有研究探讨CDK 5与癌症之间联系的机制。通过广泛的生物信息学数据挖掘过程探索CDK 5在癌症中的作用。我们通过数据库和体外实验对CDK 5基因的转录、存活、功能和结构进行了挖掘。我们发现CDK 5在大多数癌细胞系中表达水平较高,而在肝癌和脑癌细胞系中表达较低。CDK 5的高表达与肺癌的总生存期(OS)较短相关。另外,CDK 5的高表达促进肺癌细胞的增殖和转移。抑制CDK 5降低CAP 1磷酸化。CDK 5可能被证明是抗癌治疗的有效靶点。
Cyclin-dependent kinase 5 (CDK5), an atypical member of the cyclin-dependent kinase family, plays an important role in the nervous system. Recent studies have shown that CDK5 is also associated with tumors. However, few studies have been done to investigate the mechanism underlying the connection between CDK5 and cancers. To explore the role of CDK5 in cancers by using an extensive bioinformatics data mining process. We mined the transcriptional, survival, functions and structure of CDK5 gene through databases and in vitro experiments. We found that higher CDK5 expression levels in most cancer cell lines while lower expression in liver and brain cancer cell lines. High expression of CDK5 was associated with shorter overall survival (OS) in lung cancer. In addition, high expression level of CDK5 promoted lung cancer cells proliferation and metastasis. Inhibited CDK5 decreases CAP1 phosphorylation. CDK5 may prove to be a valid target of anticancer therapies.
