Accelerated senescence has been shown to occur as a primary response to cellular stresses including DNA damaging agents (e.g., ionizing radiation) and is widely believed to be caused by continuous proliferative signaling in the presence of cell cycle arrest. The present disclosure provides a method of reducing cellular senescence in non-cancerous cells following exposure to ionizing radiation. The method comprises administering to a subject before, after, or concurrently with exposure to ionizing radiation an effective amount of a compound that inhibits activation of an insulin-like growth factor receptor (IGF-1R) or a compound that inhibits a protein involved in an IGF-1R induced signaling cascade. Also provided is a composition for use in reducing cellular senescence in non-cancerous cells following exposure to ionizing radiation, the composition comprising a compound that inhibits activation of an insulin-like growth factor receptor (IGF-1R) or a compound that inhibits a protein involved in an IGF-1R induced signaling cascade.
加速衰老已被证明是对包括DNA损伤剂(如电离辐射)在内的细胞应激的主要反应,并被广泛认为是由细胞周期停滞时的持续增殖信号引起的。本公开提供了一种在非癌细胞暴露于电离辐射后减少细胞衰老的方法。该方法包括在暴露于电离辐射之前、之后或同时向受试者施用有效量的抑制
胰岛素样生长因子受体(IGF-1R)活化的化合物或抑制参与 IGF-1R 诱导的信号级联的蛋白质的化合物。还提供了一种组合物,用于减少暴露于电离辐射后非癌细胞的细胞衰老,该组合物包含一种抑制
胰岛素样生长因子受体(IGF-1R)活化的化合物或一种抑制参与 IGF-1R 诱导的信号级联的蛋白质的化合物。
