Our research is focused on the study of the implication of intracellular signaling cascades driving to pathological situations in cancer and vascular diseases.
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.

J Exp Med. 2013 Sep 23;210(10):1937-45. doi: 10.1084/jem.20121571. Epub 2013 Sep 16. ABSTRACT Understanding the direct, tumor cell-intrinsic effects of PI 3-kinase (PI3K) has been a key focus of research to date. Here, we report that cancer cell-extrinsic PI3K activity, mediated by the p110α isoform of PI3K, contributes in an unexpected way to tumor angiogenesis. […]
BMC Cancer. 2013 Aug 10;13:382. doi: 10.1186/1471-2407-13-382. ABSTRACT BACKGROUND: Cisplatin (CDDP) resistance in testicular germ cell tumors (GCTs) is still a clinical challenge, and one associated with poor prognosis. The purpose of this work was to test pazopanib, an anti-tumoral and anti-angiogenic multikinase inhibitor, and its combination with lapatinib (an anti-ErbB inhibitor) in mouse orthotopic […]
EMBO Mol Med. 2013 Jul;5(7):1067-86. doi: 10.1002/emmm.201202341. Epub 2013 Jun 14. ABSTRACT SCF (Skp1/Cul1/F-box) ubiquitin ligases act as master regulators of cellular homeostasis by targeting key proteins for ubiquitylation. Here, we identified a hitherto uncharacterized F-box protein, FBXO28 that controls MYC-dependent transcription by non-proteolytic ubiquitylation. SCF(FBXO28) activity and stability are regulated during the cell cycle […]
Int J Cancer. 2013 Nov 15;133(10):2464-72. doi: 10.1002/ijc.28259. Epub 2013 Jun 4. ABSTRACT In this article, the effectiveness of a multi-targeted chemo-switch (C-S) schedule that combines metronomic chemotherapy (MET) after treatment with the maximum tolerated dose (MTD) is reported. This schedule was tested with gemcitabine in two distinct human pancreatic adenocarcinoma orthotopic models and with […]
BMC Cancer. 2013 Mar 18;13:125. doi: 10.1186/1471-2407-13-125. ABSTRACT BACKGROUND: The malignant potential of tumour cells may be influenced by the molecular nature of KRAS mutations being codon 13 mutations less aggressive than codon 12 ones. Their metabolic profile is also different, with an increased anaerobic glycolytic metabolism in cells harbouring codon 12 KRAS mutations compared […]
