Nat Commun:利用细胞能量来进行癌症治疗

2014-03-19 Nature中文网 Nature中文网

能够利用一个癌细胞内的“能量分子”来触发药物在肿瘤所在位置的释放的一个药物载体,被发现能成功治疗小鼠的癌症。发表在本期Nature Communications上的这些发现也许能为治疗癌症提供另一个策略。Figure 1: Schematic design of the ATP-triggered Dox release system. 纳米颗粒能向肿瘤输送药物,但需要在选择性地定向肿瘤细胞方面

纳米颗粒能向肿瘤输送药物,但需要在选择性地定向肿瘤细胞方面有所改进。癌细胞经常含有为代谢提供能量的高水平ATP,这一点有可能被用于治疗。Zhen Gu及同事描述了一种纳米颗粒载体,它利用高水平的ATP来触发化疗药物Doxorubicin的释放。在有ATP存在的情况下,该载体能发生形状变化,导致药物的释放。他们发现,在实验室中这种方法在培养的细胞内和在小鼠体内都能增强由Doxorubicin诱导的癌细胞死亡。这些发现可能会导致用于将化疗药物输送到癌细胞的新策略的问世。
