Teaching Focus or Philosophy

One of the most rewarding activities I can think of is teaching. It entails transmitting our enthusiasm for knowledge, providing a valuable service to our students, and sharing our academic and personal experiences. Teaching also represents a challenge to keep up with novel discoveries, recent publications, and new trends in the scientific and industrial world. Finally, it constitutes an inestimable opportunity to interact with colleagues, students, and the University as a whole. I personally enjoy this sort of combination of intellectual and communication activities. This is the reason I have begun teaching years ago, and I continue this commitment with the same spirit.

Additional Info

My research interests center in determining the role of a family of nine serine proteases, the proprotein-convertases (PCs) in ovarian tumor progression. Most PCs activate protein precursors after limited proteolysis at the consensus sequence RXR/KR. Many of these precursors are associated with tumor progression, such as growth factors and their receptors, metalloproteinases, and adhesion molecules, pointing to a PCs role in regulating tumor progression. For instance, increased expression of these PCs has been correlated with increase histopathological grade and advanced metastatic behavior.

We have determined that increased furin, the prototype of the family, predicts poor survival in ovarian cancer, regardless the specific type of tumor. Moreover, specific blockage of its activity by protein inhibitors and siRNA technology resulted in decreased proliferation and signaling through the insulin-like receptor pathway. Interestingly, a closely related PC, PACE4, also associated with tumor progression in skin and other malignancies, showed an opposite effect in ovarian cancer; more benign and less malignant tumors expressed higher levels of this extracellular protease. In this context, therapies aimed at decreasing ovarian tumor burden should address these differences to exploit this antagonistic effect exerted by these two proteases.
