Researchers at IRB Barcelona reveal the capacity of epithelial-derived tumours to grow in the absence of a microenvironment.

Featured on the cover of the journal Proceedings of the National Academic of Sciences (PNAS), the study identifies the cell types and molecular mechanism involved in tumour initiation and growth.

The results of this study contribute to our understanding of the internal mechanisms of the tumour, which may provide a therapeutic target.

ERC Starting Grants support young talented researchers over 5 years.

The IRB Barcelona group leader will focus on the genomes of hypermutated tumours to detect cancer vulnerabilities.

Genomic instability is the main risk factor for tumour development in humans. Therefore understanding its origin and exploring therapeutic targets is paramount.

Histone 1 silences a region of the genome that causes irreparable DNA damage when translated and is lethal for the organism.

Stem cell functions continue to be governed by day and night cycles (circadian rhythms) during ageing, but their rhythms become devoted to tissue repair and not to the maintenance of tissue tone.

The two studies published in Cell and headed by Salvador Aznar Benitah at IRB Barcelona reject the scientific dogma associating ageing with the loss of stem cell circadian rhythm.

A low-calorie diet delays alterations in the rhythmic functions of stem cells and slows down ageing.

ICREA research professor Eduard Batlle is featured in the “Meet Our Scientists” video entitled “Deconstructing colon cancer”.

The video presents IRB Barcelona's Colorectal Cancer Laboratory research, which is devoted to understanding the behaviour of colon tumours and propose new cures for patients.

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.

Scientists at IRB Barcelona identify a key component of the machinery that allows Staphylococcus aureus to transfer genes that confer antibiotic resistance. 

Infection by antibiotic-resistant S. aureus is a serious threat in hospitals worldwide.

Halting the spread of antibiotic-resistant bacteria is one of the strategies available to tackle hospital infections.

Published in the journal Nature Structural & Molecular Biology, the study reveals new insights into translation regulation, an essential step in genome regulation.

These findings will help researchers to better understand pathological processes such as cancer.

The work is the first to report on the key role of the TLK2 gene in mouse embryo development.

The study solidifies an important role for both TLK1 and TLK2 in genome stability.

A massive genomics study of people with intellectual disabilities performed in the Netherlands points to patient mutations in the TLK2 gene.
