摘要 NDRG2隶属于NDRG家族(N-myc down-stream regulated gene family),是一种与细胞增殖和分化相关的基因,参与了肿瘤的发生、发展和转归,目前功能定位于抑癌候选基因。将NDRG2基因转染入U373和U138胶质瘤细胞系后,明显抑制了胶质瘤细胞的增殖;在结肠癌及高危腺瘤中,NDRG2mRNA表达量明显低于正常组织,同时随着Dukes′分级的增高,NDRG2表达有下降趋势。随着相关研究的不断深入,该基因的其他功能也逐渐被揭示:与组织胚胎的发育和细胞的分化密切相关,与神经系统的发育及其疾病的发生相关,参与了醛固酮对肾远曲小管和集合管的水钠代谢调节作用,以及多种应激反应例如:DNA损伤、缺氧等。目前其转录调控机制及其相互作用分子研究表明,NDRG2受c-Myc负调控且该调控需要Miz-1参与,同时NDRG2还是HIF-1的靶基因。维尔姆斯肿瘤基因(WT1)可以直接或间接诱导NDRG2表达等。但NDRG2生物学功能至今还尚未完全明确,值得进一步探索。
