粘合连接相关蛋白1在脑胶质瘤中的研究现状及进展

Research Status and Development of Adherens Junction Associated Protein-1 in Gliomas

  • 摘要: 粘合连接相关蛋白1(adherens junction associated protein-1,AJAP1),也称为SHREW1,最初发现是在上皮细胞粘合连接有关的一种新奇的跨膜蛋白,位于染色体1p36.32区域。大量的人类癌症病例研究证明,1p36是一个突变热点,在肿瘤发生过程中,肿瘤抑制功能的丧失与1p36区域有关。脑胶质瘤是中枢神经系统最常见的原发性肿瘤,研究显示AJAP1缺失与脑胶质瘤进展有重要关系。在胶质瘤中,AJAP1能够与β-连环蛋白(β-catenin)结合,易位至细胞核内,调节基因转录,影响细胞周期、凋亡及改变细胞骨架结构和细胞极性,抑制细胞的运动及迁移。AJAP1可能是胶质瘤重要的抑制相关靶点,与胶质瘤的发生发展、增殖、凋亡、侵袭及迁移及预后密切相关,但其机制尚未明确。本文就胶质瘤中AJAP1的研究现状及进展进行综述。

     

    Abstract: Adherens junction associated protein-1(AJAP1), also known as SHREW1, is initially discovered as a novel transmembrane protein of adherent junctions in epithelial cells. From a broad range of human cancers research, 1p36 has been a mutational hotspot which strongly suggests that the loss of tumor suppressor activity maps to this genomic region during tumorigenesis. Glioma is the most common primary central nervous system tumor. Many studies have shown that the deletion of AJAP1 has an important relationship with the development of glioma. In gliomas, AJAP1 may be translocated to the nucleus, via its interaction with β-catenin complexes, where it can regulate gene transcription, therefore having a potent impact on cell cycle and apoptosis; AJAP1 changes the structure of cytoskeleton and the polarity of cell to inhibit cell adhesion and migration. AJAP1 may be associated with the development, proliferation, apoptosis, invasion and clinical outcome of glioma, it may serve as a promising tumor suppressor-related target. However, the correlation between AJAP1 and gliomas remains unclear. In this paper, the research status and development of AJAP1 in gliomas were reviewed.
