Enhanced DNA double-strand break repair of microbeam targeted A549 lung carcinoma cells by adjacent WI38 normal lung fibroblast cells via bi-directional signaling

Publication date: Available online 23 June 2017 Source:Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis Author(s): Alisa Kobayashi, Tengku Ahbrizal Farizal Tengku Ahmad, Narongchai Autsavapromporn, Masakazu Oikawa, Shino Homma-Takeda, Yoshiya Furusawa, Jun Wang, Teruaki Konishi Understanding the mechanisms underlying the radiation-induced bystander effect (RIBE) and bi-directional signaling between irradiated carcinoma cells and their surrounding non-irradiated normal cells is relevant to cancer radiotherapy. The present study investigated propagation of RIBE signals between human lung carcinoma A549 cells and normal lung fibroblast WI38 cells in bystander cells, either directly or indirectly contacting irradiated A549 cells. We prepared A549-GFP/WI38 co-cultures and ...
