    [摘要] 未分化胚胎细胞转录因子1(UTF1)是干细胞相关基因之一，是参与胚胎干细胞分化的重要转录因子，能促进干细胞的自我更新及分化，调控胚胎细胞和生殖细胞的增殖分化。目前，对UTF1的研究大多在干细胞和生殖细胞中，而关于UTF1与肿瘤关系的研究成果较少。越来越多的证据显示，干细胞相关基因的异常表达与肿瘤发生、转移、复发及耐药性等密切相关。其转录和表观遗传胚胎程序可以在癌细胞中重新激活，使癌细胞具有干细胞表型，并参与肿瘤的发生、发展。为获得更好的疗效，部分学者长期致力于寻找各种有效的肿瘤标志物，其中UTF1在恶性肿瘤的诊断、治疗及预后方面具有重要的潜在应用价值。

    [Abstract] Undifferentiated embryonic cell transcription factor 1 (UTF1) is one of stem cell related genes and an important transcription factor involved in the differentiation of embryonic stem cells. It can promote the self-renewal and differentiation of stem cells， and regulate the proliferation and differentiation of embryonic cells and germ cells. At present， most of the research on UTF1 is in stem cells and germ cells， and there are few research results on the relationship between UTF1 and tumors. More and more evidence shows that the abnormal expression of stem cell-related genes is closely related to tumorigenesis， metastasis and relapse and drug resistance. Its transcription and epigenetic embryonic programs can be reactivated in cancer cells ......
