Sci Signal:研究人员发现关键的促癌基因

TGF-β在癌症生物学中一直是个秘密,TGF-β如何既可以阻止癌细胞的形成,又如何刺激肿瘤积极生长。 现在,美国密歇根州综合癌症中心的研究人员已经发现一个关键基因,可以解释这种矛盾,提供潜在治疗靶标。 TGF-β是已知的肿瘤抑制因子,这意味着对于保持细胞正常生长是必要的。但在某些时候,它的功能会转换成肿瘤启动子,促进癌症发展与扩散。研究人员发现BUB1可作为参与调节TGF-β受体的一个关键基因

TGF-β在癌症生物学中一直是个秘密,TGF-β如何既可以阻止癌细胞的形成,又如何刺激肿瘤积极生长。

现在,美国密歇根州综合癌症中心的研究人员已经发现一个关键基因,可以解释这种矛盾,提供潜在治疗靶标。

TGF-β是已知的肿瘤抑制因子,这意味着对于保持细胞正常生长是必要的。但在某些时候,它的功能会转换成肿瘤启动子,促进癌症发展与扩散。研究人员发现BUB1可作为参与调节TGF-β受体的一个关键基因。

这项研究发表在Science Signaling杂志上。

BUB1是众所周知的在细胞分裂中发挥作用。但是,这是首次将Bub1与TGF-beta联系起来。我们认为,这也许可以解释TGF-β作为肿瘤启动子和抑癌因子的悖论。

密歇根大学研究人员包括Shyam Nyati博士团队开发出一种方法筛选调节TGF-β受体的基因。当对肺癌和乳腺癌细胞的人类基因组720个基因进行了筛选,BUB1发挥对TGF-β信号调控的强烈作用。

BUB1显示能结合到TGF-β受体,并允许开启侵袭性细胞的生长。当研究人员阻断BUB1,它彻底关闭TGF-β途径。TGF-β已知在侵袭性癌细胞发展中有作用,研究人员也已知道,BUB1在许多不同类型的癌症中高度表达。

因为BUB1在许多类型癌症中表达,因此靶向它开发出一种药物发现可能潜在地影响多种癌症。目前已开发出靶向BUB1的化合物,但还没有准备好在患者中开展测试。初始实验室测试表明,这种BUB1的抑制剂可以非常特异性靶向BUB1,而不会损坏细胞的其他部分。
