摘要: 抑癌基因与张力蛋白同源10q丢失的磷酸酶基因(Phosphatase and Tensin Homology deleted from Chromosome ten,PTEN)为公认的肿瘤抑制基因,表达的PTEN蛋白具有双磷酸酶活性-脂质磷酸酶和蛋白磷酸酶,可通过抑制PI3K/Akt途径调节多种分子,进而参与肿瘤的发生发展。目前,一些学者致力于PTEN调节机制的研究,表明PTEN可在基因和蛋白水平受相关因素的调节。本文就目前已知的调控及机制作一综述。

Abstract: PTEN (Phosphatase and Tensin Homology deleted from Chromosome ten),a putative antioncogene,encodes a PTEN protein that has a dual specificity phosphatase activity with both protein phosphatase and lipid phosphatase,which is capable of regulating lots of molecules through inhibiting the PI3K/Akt signaling pathway.Recently,some scholars dedicate to the modulation of PTEN,which demonstrates that PTEN can be regulated by multiple factors in the level of gene and protein.This review briefly summarizes current knowledge about the modulation of PTEN and its mechanisms.
