Doctor Alfonso Calvo, researcher in the area of Oncology at the CIMA, led the work with the special collaboration of Doctor Ignacio Gil Bazo, cancer specialist from the University Hospital. The study made up a significant part of Mr Raúl Catena’s PhD thesis.
For this research, recently published in the scientific journal Oncogene, a transgenic mouse model which presented a greater tendency for developing metastasis was employed. The increase in what is known as the Vascular Endothelial Growth Factor (VEGF) in its mammary glands triggered profound changes in the tumoural structure, which enabled the malignant cells to leave the tumour and invade the lungs.
Finally, the pattern of genes responsible for this tumoural migration to the lungs was analysed and this was compared to that shown by women with breast tumours with pulmonary metastatic affectation. It was shown that five of these genes were common to the animal model and patients with breast cancer.
Most effective ways of treatment
According to the results of this study, of the five genes identified, the Tenascina-C gene seems to be a good therapeutic target for the treatment of metastatic breast cancer. In fact, the blocking of the expression of this gene in the animal model enabled a significant reduction, both in tumour growth and in the incidence of pulmonary metastasis.
This new discovery in the complex network that is the metastasis process of tumours provides key data on the knowledge of cancer and its spreading, at the same time identifying new targets for which new pharmaceutical medicines that contribute to more efficacious treatment of this disease can be designed.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
