SCIENCE:肿瘤细胞为什么会进化出耐药性?

2020-07-27 MedSci原创 MedSci原创

在微生物中,进化上保守的机制通过应激诱导突变(SIM)可以促进其对恶劣条件的适应。类似的过程可能是人类癌症进展和治疗失败的基础。

在微生物中,进化上保守的机制通过应激诱导突变(SIM)可以促进其对恶劣条件的适应。类似的过程可能是人类癌症进展和治疗失败的基础。

最近,研究人员描述了在非遗传毒性药物选择下,人类癌症的多种体外和体内模型中的SIM,其反常地以牺牲内在健康成本来增强适应性。

一个全基因组的方法确定了雷帕霉素的机械靶点(MTOR)作为一个压力感应器,介导多个癌症类型和条件下的SIM。

这些观察结果与耐药性的两阶段模型相一致,其中遗传多样性最初的快速扩张被内在的适应性惩罚所抵消,随后在新的条件下正常化到完全适应。

这个模型提出了合成致死策略,以最大限度地减少对抗癌治疗的抗药性。

为什么肿瘤耐药性难以解决?因为耐药性的根源不仅限于单个基因!

一项新的研究表明,寻找更多的个体基因来预测对乳腺癌治疗的反应可能不起作用。相反,科学家和临床医生们需要注意基因网络中的异常基因。耶鲁大学的研究人员们于10月10日在《肿瘤学杂志》上发表的论文中报道。耶鲁大学研究了200名患有HER2阳性乳腺癌的患者的所有基因(约15%的乳腺癌具有大量HER2基因拷贝)。大约一半的患者对HER2靶向治疗反应良好,但一半对靶向治疗没有反应。然而,他们找不到单个基因异常

科学家设计一种多药物纳米粒“组合拳”治疗肿瘤的新方法,克服肿瘤耐药性

最近,美国滑铁卢大学和哈佛医学院的研究人员,设计了一种新的革命性的癌症治疗方法将不同的致死药物因子组合包装成单一的纳米颗粒。这种二合一策略可确保耐药性从未有机会得以发展,从而将合适的策略进行组合,来摧毁生存的癌细胞。 如果使用联合疗法治疗癌症,癌症可能就“game over”了。然而,这些疗法必须以正确的顺序在正确的时机提供正确的药物。同时,所有的药物必须作用在相当狭窄的范围比如单个细胞。
