项目摘要
We found that phospholipase C・, an effector of the ras oncogene product (Ras), plays a crucial and universal role in tumor promotion through triggering inflammatory reactions, and analyzed the underlying action mechanisms. Furthermore, we elucidated the molecular mechanism for the conformational dynamics of the GTP-bound Ras. By using a new strategy based on this mechanism, we developed small molecule Ras inhibitors, which exhibit equivalent or even higher anti-tumor activities in animal models compared to the existing anti-cancer drugs, through an in silico approach.
我们发现ras癌基因产物(Ras)的效应子磷脂酶C·通过触发炎症反应在肿瘤的促发中起着重要而普遍的作用,并分析了其作用机制。此外,我们阐明了GTP结合的Ras的构象动力学的分子机制。通过使用基于这种机制的新策略,我们开发了小分子Ras抑制剂,与现有的抗癌药物相比,它们在动物模型中表现出相当甚至更高的抗肿瘤活性。
