Oncogene-induced reactive oxygen species (ROS) have been proposed to be signaling molecules that mediate proliferative cues. However, ROS may also cause DNA damage and proliferative arrest. How these apparently opposite roles can be reconciled, especially in the context of oncogene-induced cellular senescence, which is associated both with aberrant(More)
Cellular senescence was historically discovered as a form of cellular ageing of in vitro cultured cells. It has been under the spotlight following the evidence of oncogene-induced senescence in vivo and its role as a potent tumour suppressor mechanism. Presently, a PubMed search using keywords 'cellular senescence and cancer' reveals 8398 number of(More)
Work carried out primarily in the laboratory of Fabrizio d'Adda di Fagagna unveils the mitogenic properties of Ras-induced reactive oxygen species (ROS) and their relationship with the DNA damage response. Combined data from studies of cultured cells, zebrafish models, and clinical material consistently support a role of the RAS-RAC1-NOX4 axis in ROS(More)
