Oncogene:FOXA1可抑制前列腺癌神经内分泌的分化

2017-03-24 AlexYang MedSci原创

神经内分泌前列腺癌(NEPC)越来越成为一种临床挑战。来源于前列腺肿瘤的神经内分泌(NE)细胞的机制到目前还很不清楚。 之前研究指出,FOXA1是叉头基因家族的一个转录因子并且参与了前列腺上皮细胞的分化。最近,研究人员通过区分表型的变化和NEPC分子标记的表达,阐释了FOXA1功能缺失促使了NE的分化。研究人员推论,这种现象是由FOXA1结合在白细胞介素8(IL-8)的启动子上来直接抑制

神经内分泌前列腺癌(NEPC)越来越成为一种临床挑战。来源于前列腺肿瘤的神经内分泌(NE)细胞的机制到目前还很不清楚。

之前研究指出,FOXA1是叉头基因家族的一个转录因子并且参与了前列腺上皮细胞的分化。最近,研究人员通过区分表型的变化和NEPC分子标记的表达,阐释了FOXA1功能缺失促使了NE的分化。研究人员推论,这种现象是由FOXA1结合在白细胞介素8(IL-8)的启动子上来直接抑制IL-8的表达而产生的,且之前的报道表明IL-8是个趋化因子并在NEPC中表达量被提高。更深入研究表明,IL-8上调激活了MAPK/ERK信号通路,导致ERK的磷酸化和烯醇酶2(ENO2)的表达。IL-8敲除或者ERK的抑制,从另一方面,抵消了FOXA1功能缺失引起的NE分化。研究人员通过异种种植小鼠模型分析确认了NEPC肿瘤中FOXA1功能缺失与恶性腺癌成相互对应的关系。更重要的是,和人类原发性前列腺癌和雄激素抵抗性前列腺癌比较,人类NEPC肿瘤中FOXA1表达量下调了,并且其表达量和ENO2表达量呈负相关关系。这些发现表明了FOXA1转录抑制了IL-8表达。另外,IL-8的表达可激活MAPK/ERK通路从而促进前列腺癌细胞的NE分化。最后,研究人员指出,该研究数据强烈地表明了FOXA1的缺失也许在促进前列腺癌细胞到NEPC的转变中起着重要作用。另外,IL-8和MAPK/ERK通路也许是介入治疗很有希望的靶标。
