Research Bio

Receptor-mediated Modulation of Gene Expression and Association with Biological and Toxic Responses

While genetics is known to influence the initiation, progression, and outcome of a variety of human diseases including cancer, it is clear that these are also influenced to a great extent by a number of other factors. These include, for example, exposure to chemicals in the environment, diet and aging.

The overall goal of the research in this laboratory is to determine how certain chemicals and substances in the diet influence, in both a positive and negative manner, the processes that influence the progression and outcomes of disease.
By understanding the molecular mechanisms by which these factors act, we will also be providing information that can be used in the design of tools for more effective diagnosis and treatment of these diseases.
