Researchers from the @bbglab at @IRBBarcelona have contributed to the discovery of #LesionSegregation, explaining how DNA damage caused by chemical mutagens is not repaired immediately and can create more genetic diversity in tumours.

The work has been published in the journal @nature.
“This process, which we named #lesionsegregation, is very revealing to understand how mutations occur, a key step in the evolution of cancer,” says @nlbigas.

“Persistent DNA lesions induced by chemotherapeutic agents segregate and produce several generations of further mutations. We need to be aware of this therapeutically, and in future drug development," explains @mst_paralogue from @EdinburghUni.

We are really excited that our work showing how pervasive lesion segregation shapes cancer genome evolution is published today in @nature.

Here’s a #tweetorial to explain our #LesionSegregation findings...

Human cancer genomes are unavoidably confounded by genetic and environmental differences. Such intrinsic heterogeneity hinders our ability to disentangle biases of DNA damage and repair. So we used an in vivo oncogenesis model to re-run cancer evolution hundreds of times.

WGS of mutagen-initiated tumours showed a high burden of point mutations, comparable to human cancers caused by exogenous mutagens, e.g. lung and skin cancer. The tumours are dominated by thymine mutations (“DEN signature”) and driver mutations in the EGFR-RAS-RAF pathway.
