A team of scientists headed by Roger Gomis at IRB Barcelona reveals one of the mechanisms that allows metastatic cells to leave a latent state.

The time needed for breast cancer metastases (secondary lesions caused by cells that have escaped from the original tumour) to develop varies between patients, and little is known about the mechanisms that govern latency (the dormant state of cells that have already spread through the body). A study headed by ICREA researcher  Roger Gomis at the Institute for Research in Biomedicine (IRB Barcelona) has identified the genes involved in the latent asymptomatic state of breast cancer metastases. The work sheds light on the molecular basis underlying how the expression of certain genes facilitates the spread of metastatic lesions.

The team has studied the most common kind of breast tumour—estrogen-positive (ER +) and accounting for 80% of breast cancer tumour cases—that is characterised by a long period of latency with no symptoms. The study has been published today in Nature Cell Biology.

MSK1, the protein that keeps tumour cells dormant

The team has identified the protein kinase MSK1 as a key regulator of dormant or latent metastases. Using clinical samples from patients, the scientists have confirmed that ER + breast cancer tumours that do not express MSK1 are associated with a risk of earlier relapse, while those that express this molecule will form metastases later.

“We are interested in understanding the mechanisms underlying metastasis and the time component of this process. Until now, little was known in preclinical models about the mechanisms that allow breast cancer cells to leave the latent state and even less is known in patients," explains Roger Gomis, head of the Growth Control and Cancer Metastasis Lab.

The researchers believe that in the future this discovery may benefit patients in two ways. Firstly, it will help to identify those with an imminent risk of relapse and to adjust the treatment for this prognosis. Secondly, attempts could be made to design a treatment to mimic the function of MSK1 kinase, with the aim to maintain metastatic lesions in a latent and asymptomatic state for as long as possible.

The study published today was done in collaboration with the labs headed by Salvador Aznar Benitah and Angel R. Nebreda, both members of IRB Barcelona’s Oncology Programme, and with the labs led by Violeta Serra, at the Vall d’Hebrón Institute of Oncology (VHIO), Aleix Prat, at the Hospital Clínic de Barcelona, and Joan Albanell, at the Hospital del Mar. The first author of the article is Sylwia Gawrzak, a former "la Caixa" PhD student at IRB Barcelona who is currently doing a postdoc in EMBL, Heidelberg, Germany.

The study was funded by the Minstry of Economy and Competitiveness  through ERDFs, the Generalitat de Catalunya through AGAUR, the BBVA Foundation, Worldwide Cancer Research and the Centro de Investigación Biomédica en Red de Cáncer (CIBERONC) (Biomedical Research Networking Centre in Oncology), in which the researcher Roger Gomis participates.

About IRB Barcelona

Created in 2005 by the Generalitat de Catalunya (Government of Catalonia) and University of Barcelona, IRB Barcelona is a Severo Ochoa Centre of Excellence, a seal that was awarded in 2011. The institute is devoted to conducting research of excellence in biomedicine and to transferring results to clinical practice, thus improving people’s quality of life, while simultaneously promoting the training of outstanding researchers, technology transfer, and public communication of science. Its 25 laboratories and seven core facilities address basic questions in biology and are orientated to diseases such as cancer, metastasis, Alzheimer’s, diabetes, and rare conditions. IRB Barcelona is an international centre that hosts 400 employees and 32 nationalities. It is located in the Barcelona Science Park. IRB Barcelona forms part of the Barcelona Institute of Science and Technology (BIST) and the “Xarxa de Centres de Recerca de Catalunya” (CERCA).

How to prevent colorectal cancer from metastasizing?

The “Preguntas Big Van” section of the newspaper La Vanguardia interviewed Eduard Batlle, ICREA researcher and head of the Colorectal Cancer Lab at IRB Barcelona, about his collaboration with the Centro de Análisis Genómico regarding the study of colorectal tumour samples using the new unicellular analysis method. “This technique allows us to see what is happening inside the tumour at a level of detail that was unimaginable 5 years ago,” says Batlle.

The most common breast cancer under siege

The newspaper ABC has reported on a new project to be launched by IRB Barcelona researcher Roger Gomis thanks to a grant from the Fundación Fero y Mango. Focusing on luminal breast cancer, one of the most common subtypes, the project aims to decipher the “dialogue” between tumour cells and bone stem cells. This information can then be used to design therapeutic targets and to limit the capacity of these cells to metastasize. “This is a groundbreaking approach to tackle metastasis in this kind of cancer,” says Gomis.

The DNA damage caused by “chemo”

The newspapers El Mundo, La Vanguardia and Diari Ara, the TV station TV3 and the radio stationsCatalunya Ràdio andRAC1, among other media, have echoed on a study by the Biomedical Genommics lab, headed by Núria López, published in Nature Genetics. The study has for the first time determined the genetic mutations caused by various therapies used to treat cancer.
