Researchers at IRB Barcelona explain the origin of the mysterious periodicity of the genome

The team headed by Núria López-Bigas has published an article in Cell about what might have favoured the periodicity of certain base pairs in the genomes of eukaryotic organisms.

The structure adopted by DNA when packaged inside cells influences the periodicity observed.

The “DNA corrector” is more efficient in the most important regions of the genome

A study published by IRB Barcelona in Nature Genetics demonstrates that the error (mutation) surveillance and repair system shows greater efficiency in the protein-coding regions of genes.

Errors made by 'DNA spellchecker’ revealed as important cause of cancer

Fran Supek (IRB Barcelona) and Ben Lehner (CRG) identify important processes that create mutations that cause cancer by studying the genomes of more than 1,000 tumors.

Many mutations in human cancers are caused by mistakes made by a repair mechanism or ‘DNA spellchecker’ rather than the actual damage to DNA caused by the environment.

Sunlight and alcohol consumption increase the rate at which this happens, resulting in more mutations in the most important parts of our genomes.

 

IRB Barcelona intensifies its research on cancer with two new recruits

As of November, Núria López-Bigas, winner of the 2016 Banco Sabadell Foundation Prize for Biomedical Research, will join IRB Barcelona to continue her research on cancer using computational biology.

The Institute has also recruited Croatian scientist Fran Supek, who will launch his laboratory in 2017.
