Abstract 2491: Metformin sensitizes human lung cancer xenografts to ionizing radiation: Response of the AMPK pathway

Abstract Introduction : Radiation therapy is a standard therapeutic modality in lung cancer (LC). Unfortunately, LC demonstrates radiation resistance and poor response to even high doses of chest radiotherapy. Therefore, there is an urgent need to develop effective and well tolerated radiation sensitizers in LC. Recently, we showed that ionizing radiation (IR) and metformin (MET) activate the energy sensor and tumor suppressor …
