Dr. Mariana De Lorenzo
Mariana De Lorenzo, Ph.D., a postdoctoral fellow working with Andrew Dannenberg, M.D. and Kotha Subbaramaiah, Ph.D. in the Department of Medicine of Weill Medical College of Cornell University, was awarded a two-year research fellowship by the Cancer Research Foundation of America

Dr. De Lorenzo received her Ph.D. from the University of Buenos Aires in 2001. As a doctoral student, she worked on both tumor metastasis and angiogenesis. The title of her newly funded project is: "Tobacco smoke, cyclooxygenase-2 and prevention of aerodigestive cancer." There is considerable evidence that cyclooxygenase-2 (COX-2), a rate-limiting enzyme in prostaglandin biosynthesis, is important for both the development and progression of cancer. Smoking tobacco is a risk factor for cancers of the aerodigestive tract. In preliminary studies, tobacco smoke induced COX-2 and prostaglandin production in cell lines derived from the aerodigestive tract. During the next two years, Dr. De Lorenzo will build upon these initial findings. She will elucidate the molecular mechanisms by which tobacco smoke induces COX-2. Moreover, she will utilize the cell culture systems that this group has established to identify chemopreventive (anti-cancer) agents that prevent the induction of COX-2 by tobacco smoke. The long-term goal of this research is to develop mechanism-based strategies to prevent tobacco-related cancers.
