Abstract :

R eplication stress response (RSR) is a subset of DNA damage response that safeguards the replication process. It has been known that in normal cells, hyperproliferative activity caused by oncogene activation leads to replication stress and to the activation of RSR. The activation of RSR consequently triggers cellular senescence or apoptosis to prevent cell transformation. Recently, my lab has developed a unique cell model to study how normal cells respond when they are simultaneously challenged with oncogenic stress and the loss of RSR. Intriguingly, it was found that these RSR defective cells exhibited many characteristics of cancer stem cells, including possessing cancer stem cell markers and EMT (epithelial-mesenchymal transition). Present work therefore functionally links RSR defect with cancer stemness during the process of cellular transformation.
