该方案详细介绍了非遗传缺陷转录伸长的体外鼠癌模型。在这里,CDK9的慢性抑制用于抑制RNA Pol II沿亲炎反应基因的生产性伸长,以模仿和研究临床上过度服务的TE绝对现象,存在于大约20%的所有癌症类型中。

鉴于TEdeff癌症是免疫治疗的一大障碍,我们的药理学模型是一个有利的工具,因为它适当地模仿了此类癌症中观察到的广泛转录和表观遗传缺陷,它允许人们研究这些非遗传异常,以获得新的见解,发现现有药物的新用途,或找到针对此类癌症的新策略。这是一个易于建立和通用的模型,研究癌症的转录伸长缺陷,使一个人能够研究肿瘤-免疫相互作用在体外和体内。该方法也适用于人类癌线。

我们已经在T47D和CAL51上进行了短期测试,从而产生类似的TEdeff特性。我们在这里描述的协议提供了一个基本框架,以最小化通过慢性 CDK9 抑制生成 TEdeff 样功能的关键已知变量。然而,必须注意优化其他穆林线的黄曲二维剂量。
