KLF4 is a member of the erythroid Kruppel-like factor (EKLF) multigene family that is highly expressed in the differentiating layers of the epidermis (1, 2). KLF4 plays a critical role in the differentiation of epithelial cells and is essential for normal gastric homeostasis (2,3). Depending on the target gene, KLF4 can function as both a repressor and activator of transcription (4). Research studies suggest this protein may function as either a tumor suppressor or an oncogene depending on tumor type, with up-regulation in human squamous cell carcinoma of the head and neck and down-regulation in colorectal carcinoma (5,6). The in vitro reprogramming of somatic cells to an embryonic-like state has been achieved by retroviral transduction of four factors: Oct-3/4, Sox2, c-Myc, and KLF4 (7). These induced pluripotent stem cells (iPS) are of great therapeutic interest as they exhibit the key characteristics and growth properties of pluripotent stem cells (8,9).

KLF4是erythroid Kruppel-like factor (EKLF)多基因家族一员,在分化的表皮层中高表达(1,2)。KLF4在表皮细胞分化过程中发挥重要功能,对于正常胃稳态是必须的(2,3)。KLF4既可以作为转录抑制子也可以作为激活子,这取决于它的靶基因(4)。研究提示该蛋白的即可作为抑癌也可以作为促癌基因,这取决于肿瘤的类型,它在人头部和脖子的扁平上皮癌中表达上调,在结肠癌中低表达(5,6)。体细胞的体外重编程为胚胎样细胞是通过四个逆转录因子:Oct-3/4, Sox2, c-Myc, 和 KLF4实现的 (7)。诱导的多潜能干细胞(iPS)是研究热点,因为他们表现了多潜能干细胞的重要特征和生长性能(8,9).
