垂体肿瘤转化基因(PTTG)也称为securin,是参与许多生物学功能的重要基因,包括抑制姐妹染色单体分离、DNA修复、器官发育以及血管生成和转移因子的表达和分泌。增殖的癌细胞和大多数肿瘤表达高水平的 PTTG。体外过表达PTTG可诱导裸鼠细胞转化和肿瘤发展。 PTTG表达水平与肿瘤进展、侵袭和转移相关。最近的研究表明,肿瘤细胞系和体内肿瘤中 PTTG 的下调会导致肿瘤生长的抑制,表明其在肿瘤发生中的重要作用。在这篇综述中,我们重点关注 PTTG 结构、亚细胞分布、细胞功能和在肿瘤进展中的作用,并就该基因用于癌症治疗的可能探索提出建议。
Pituitary tumor transforming gene (PTTG), also known as securin is an important gene involved in many biological functions including inhibition of sister chromatid separation, DNA repair, organ development, and expression and secretion of angiogenic and metastatic factors. Proliferating cancer cells and most tumors express high levels of PTTG. Overexpression of PTTG in vitro induces cellular transformation and development of tumors in nude mice. The PTTG expression levels have been correlated with tumor progression, invasion, and metastasis. Recent studies show that down regulation of PTTG in tumor cell lines and tumors in vivo results in suppression of tumor growth, suggesting its important role in tumorigenesis. In this review, we focus on PTTG structure, sub-cellular distribution, cellular functions, and role in tumor progression with suggestions on possible exploration of this gene for cancer therapy.
