摘要
转移生长因子β(TGF-β)超家族的成员及其下游的Smad信号转导分子与肿瘤的发生与发展有密切关系。在前列腺癌中,TGF-β/Smad信号通路被激活,在细胞水平调节细胞粘附性、肌丝系统、细胞周期等方面,并在分子水平调节特异基因的表达。同时其他的信号通路如MAPK和PI3K/Akt/mTOR通路以及一些基因和蛋白分子对于TGF-β/Smad信号通路的表达也具有调控作用。本文对近年来前列腺癌中关于TGF-β及Smad信号的表达、作用及调控方面的研究进展作一综述,并对其在前列腺癌基础研究与靶点治疗中的意义作一展望。
Tumorigenesis and cancer progression are closely associated with the transforming growth factor-β (TGF-β) and its downstream component Smad. The TGF-β/Smad signaling pathway, which is activated in prostate cancer, has a regulatory effect on cell adhesion, the actin filament system and cell cycle, as well as the expression of specific genes. Meanwhile, other protein signals such as MAPK and PI3K/Akt/mTOR and some genes may act on the expression of the TGF-β/Smad pathway. This article updates recent researches on the expression, action and regulatory effect of the TGF-β/Smad signaling pathway in prostate cancer.
