摘要: 逆转录病毒结合位点-1(Evi-1)基因是首先在小鼠粒细胞白血病发现的逆转录病毒结合位点。鼠和人类的Evi-1基因91%的核酸序列和94%的氨基酸序列同源。在恶性血液系统病变及其他实体肿瘤中高表达,致肿瘤机制主要为通过抑制Smads而抑制转化生长因子-β(TGF-β)信号途径,调节细胞周期,促进血管生成,抑制JNK及激活AP-1等。

Abstract: Ecotropic viral integration site-1 (Evi-1) gene is first identified as a binding site for retrovirus in murine myeloid leukemia. The human homologue with the murine in leukemia oncogene Evi-1 is about 91% of nuclear sequence and 94% of amino acid. Evi-1 gene is high expressed in myeloid malignancies and other tumors. The main tumorigenic mechanisms of Evi-1 gene include inhibiting TGF-β signal path by depressing Smad3, adjusting cell cycle, promoting angiogenesis, inhibiting JNK, activating AP-1, and so on.
