Nature study links inherited genetics to cancer risk and tumour evolution
A study published in the journal Nature provides the first direct evidence that inherited genetic variation shapes how tumours develop after DNA‑damage exposure. Researchers exposed four genetically distinct mouse strains to an identical dose of the liver carcinogen diethylnitrosamine (found in tobacco smoke and some processed foods) at age 15 days. Nearly 600 tumours were analysed, revealing that each genetic background followed different evolutionary routes, although many tumours ultimately activated the same biological pathways.
The work, led by Professor Duncan Odom together with colleagues from the Cancer Research UK Cambridge Institute, the German Cancer Research Centre (DKFZ) and collaborators in the United Kingdom, United States and Europe, argues that cancer‑prevention and screening strategies must take inherited genetics and population diversity into account, paving the way for more personalised approaches to risk assessment and therapy.
