Ageing and cancer share some common biology. Genomewide examinations show that overlapping genes between them can be classified into functional categories and pathways, e.g., cell cycle regulation, metabolic processes, DNA damage response, apoptosis, the P53 signalling and chemokine signalling pathway, and the immune/inflammatory response . Currently, both the cause-effects “mutation” theory of cancer and the free radical theory of ageing are under question. The former has difficulty explaining how cancers arise, and why conventional chemotherapy succeeds or fails . Similarly, the idea that the macromolecular damage from toxic reactive oxygen species is the cause of ageing now faces challenges from evidences regarding the rival mTOR-centric model .
