Patent ID: 10799473

Abstract:
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.
