Cancer mortality and senescence: Is redox therapy an option?

Patient genomics and mouse functional genetics have revealed that senescence is a barrier to metastatic progression of prostate cancer. Many efforts focus on eliminating senescent cells, whereas others aim to elucidate distinct characteristics that set them apart from normal and aging cells. Here, we discuss how exploration of the redox state of senescent cells could help define new markers and pro-oxidant vulnerabilities, drawing analogy to what is known about the redox sensitivity of proliferating cancer cells.
