Research progress of PTEN pathway in anti-angiogenesis of tumors / 白血病·淋巴瘤

ABSTRACT

PTEN is a dual protein/lipid phosphatase.As a negative regulator of PI3K/Akt pathway,PTEN not only plays an important role in multiple cellular functions such as cell metabolism,proliferation,cell-cycle progression,but also modulates angiogenesis via down-regulating PI3K-Akt-VEGF-HIF pathway in many tumors.In this review,the recent studies on the roles and mechanisms of PTEN in regulating tumorigenesis and angiogenesis are discussed to explore PTEN as a favorable prospect target in the treatment of angiogenesis.
