Twenty leading authorities in cancer stem cell research, including Hans Clevers, John E. Dick, Joan Massagué and Sean J. Morrison, meet in Barcelona for the first time, invited by IRB Barcelona and the BBVA Foundation.

<p>In vitro culture of colon cancer tumour cells. The tumour cells (in green) have deactivated the positional receptors and spread to invade the tissue occupied by the red cells.<br /></p>

Tumour cell growth is limited to compartments by the action of two receptors that confine these spaces.

Research conducted by investigators from IRB Barcelona appears this week in Proceedings of the National Academy of Sciences PNAS.

<p>Protein Hedgehog (hh -in blue) induces Mtv protein -in red-. Mtv together with other molecules repress Hh expression</p>
22 Jun 2007

The protein Hedgehog is fundamental to the development of multiple organs. Errors in its expression are linked to skin cancer.

The goal of this activity, entitled “How does the scientific method work? Let’s do biomedical research!”, is to stimulate the creativity and thinking in students between the ages of 10 and 12, and to contribute to their educational activities. The project is part of the PCB’s “Science and Society” outreach programme, which aims to help improve the scientific culture of society in general, to promote research, and foster vocations in this field.

During the activity – which lasts from 10 to 12.30 in the mornings – students attend a theatre workshop in which two crazy scientists complete experiments using the scientific method, while explaining the function of cells, DNA...

The shortening and disappearance of telomeres in chromosomes is associated with the appearance of certain types of cancer.

<p>Interaction between the ubiquitin ligase (larger molecule) and the LMP2A membrane protein sequence (blue line). <br /></p>
18 Apr 2007

Unless you are a molecular biologist, you may not have heard the term ubiquitin. Given its essential role in the cell, however, it is likely that its protagonism and popularity will increase. One of the processes in which ubiquitin plays a relevant role is in the degradation of proteins. In the cell, the generation of proteins is just as important as their destruction, as well as the maintenance of a correct balance between both processes.

Proteins become candidates for degradation when they are defective, when they have completed their function and are no longer necessary, or when they belong to pathogenic organisms. Ubiquitin attaches itself to these proteins as if it were an...
