The molecular signaling cascades that take place inside the cells are essential to respond to changes in their environment or to alter their homeostasis, for example, at the level of cell proliferation, movement, growth or metabolism. Understanding how these mechanisms of signal transduction work can explain how biological processes are controlled in a normal physiological context, but also, the alterations that take place in many pathologies. Our group investigates this in two pathological contexts: The first is ovarian epithelial cancer, where we study the pathways involved in metastasis and the mechanisms of resistance to therapies. A second context is a rare vascular disease, HHTs, in which, in collaboration with the group led by Toni Riera (Hospital de Bellvitge), we study which signaling pathways are altered in patients with mutations that cause this disease, and how treat them with new drugs.
