Insulin/IGF-1 signaling plays a central role in control of cellular metabolism and survival, while insulin receptor substrate (IRS) protein -1 and -2 and downstream PI-3 kinase→Akt→Foxo1 signaling cascade play key roles in many functions of insulin/IGF-1. Dysregulation of this branch of signaling cascades may provide a mechanism for insulin resistance as we observed in cells, animals, and even humans. Targeting this branch of IRS→Foxo1 signaling may provide us with fundamental strategies for drug development in the future.
胰岛素/胰岛素样生长因子-1信号传导在细胞代谢和存活的调控中起核心作用,而胰岛素受体底物(IRS)蛋白-1和-2以及下游的PI-3激酶→Akt→Foxo1信号级联在胰岛素/胰岛素样生长因子-1的许多功能中起关键作用。正如我们在细胞、动物甚至人类中所观察到的,这一信号级联分支的失调可能为胰岛素抵抗提供一种机制。针对IRS→Foxo1信号传导这一分支可能为我们未来的药物开发提供基本策略。
