Sci Rep:在前列腺癌细胞中,白花丹素诱导的差异基因表达受雄激素受体调控

2018-02-24 AlexYang MedSci原创

小鼠获得性前列腺PTEN-P2肿瘤或者体内前列腺组织的 5-hydroxy-2-methyl-1,4-naphth oquinone(白花丹素)处理能够在去势小鼠中导致肿瘤退化,但是在完整的小鼠中没有上述情况。这表明了由于白花丹素处理,双氢睾酮(DHT)在这些睾丸中的产生也许阻止了细胞的死亡,但是潜在的机制仍旧不清楚。最近,有研究人员在白花丹素和DHT组合处理的细胞中进行了RNA-seq测序分析,

小鼠获得性前列腺PTEN-P2肿瘤或者体内前列腺组织的 5-hydroxy-2-methyl-1,4-naphth oquinone(白花丹素)处理能够在去势小鼠中导致肿瘤退化,但是在完整的小鼠中没有上述情况。这表明了由于白花丹素处理,双氢睾酮(DHT)在这些睾丸中的产生也许阻止了细胞的死亡,但是潜在的机制仍旧不清楚。

最近,有研究人员在白花丹素和DHT组合处理的细胞中进行了RNA-seq测序分析,并且分析了差异化的基因表达,旨在获得雄激素和白花丹素之间的互作情况。

研究发现,DHT和白花丹素可协同加强改变许多基因的表达,但是当单独使用时并不能出现基因表达的差异化。最后,研究人员指出,这些实验阐释了许多基因因DHT处理诱导的mRNAs表达的增加可以由白花丹素剧烈的下调,并且许多转录本对白花丹素的响应的变化是以一个DHT依赖的方式。这些研究表明了雄激素受体能够对白花丹素对基因表达的一些影响进行调控。

Prostate:白花丹素可以提高治疗前列腺癌的雄激素疗法阻断效果

白花丹素是治疗前列腺癌的候选药物。之前的研究表明了白花丹素也许可以提高雄激素阻断疗法(ADT)的治疗效果。最近,有研究人员评估了将白花丹素和ADT结合在前列腺癌小鼠模型中进行试验,从而支持白花丹素的临床应用。研究人员利用新的芝麻油配方进行白花丹素口腔服用,并在小鼠中进行了标准的毒性研究。对肿瘤生长研究,研究人员将小鼠前列腺癌细胞团嫁接到前列腺组织上来形成肿瘤。小鼠被分成不同处理的小组,肿瘤大小通过
