Chronic Inflammation and Cancer


We are investigating how inflammatory oxidants such as hydrogen peroxide and hypochlorous acid kill tumor cells and how they may affect tumor cell recognition and elimination by the immune system. Solid tumors are often infiltrated by inflammatory phagocytes which can generate reactive oxygen species within the tumor tissue. Our studies focus on determining how these oxidants kill tumor cells so that we may better understand mechanisms of cell death. In addition, we are studying how these oxidants may influence the ability of chemotherapy drugs to kill cancer cells. The overall goal of the research is to find ways to improve cancer treatment by using our knowledge of basic biochemical and immunological mechanisms to develop novel therapeutic approaches for eliminating tumors.
