PLoS ONE:前列腺癌转移的关键信号FOXO4/RUNX2被揭示

在许多致死性癌症患者中,超过90%的患者死亡都是因为癌细胞的转移,寻找干扰癌细胞转移的关键路径对于开发新型疗法来抑制肿瘤扩散非常关键;近日,刊登在国际杂志PLoS ONE上的一篇研究论文中,来自帕克癌症研究所(Roswell Park Cancer Institute)的研究人员通过研究鉴别出了一种癌症转移的新型抑制子,这或许为开发治疗前列腺癌及其它恶性实体瘤的新型有效疗法提供希望。

我们都知道,信号路径PI3K/AKT的激活可以诱导前列腺癌恶化进入到阉割耐受阶段,这个阶段往往是前列腺癌最恶化的一个阶段,也是最为致命的。文章中,研究者利用全基因组遗传筛选技术,鉴别出了一种未知的癌症转移抑制蛋白-FOXO4蛋白,其属于人类机体细胞产生的常见蛋白家族的一种。

研究者Gelman教授表示,许多公开的癌症基因组数据库数据显示,相比原发性前列腺癌,FOXO4在转移性的前列腺癌中处于关闭状态;而我们的研究发现,FOXO4基因可以关闭那些控制恶性肿瘤细胞发生特殊转移行为的基因的表达,比如其可以入侵其它组织随后在组织中生长并且繁殖。

FOXO4可以通过结合并抑制RUNX2蛋白的表达来抑制癌性肿瘤的扩散,研究者在文章中发现了一种可以控制前列腺癌恶性转移的新型分子回路;这项研究揭示了RUNX2蛋白在促进癌症转移中的重要作用,而且也揭示了抑制RUNX2蛋白的药物可以抑制前列腺癌的转移。研究者在揭示癌症转移对患者机体引发严重影响的同时,也希望他们的研究成果可以帮助早日开发出治疗癌症转移的新型潜在疗法。

如今,研究者正同马里兰大学的研究人员进行联合研究来检测实验性药物制剂CADD522在抑制前列腺癌转移上表现出的有效性,而CADD522是RUNX2的抑制剂。
