Research Topics

Mechanisms of estrogen hormone action, effects of endocrine disruptors, hormonal carcinogenesis; reproductive biology; coupling of receptor signal. A variety of diverse chemicals exhibit endocrine disrupting activities. The effects of these environmental substances and their mechanism of action are poorly understood. The research problem is being addressed by using three interrelated experimental approaches. (1) Investigate the structural basis of ligand interactions with the estrogen receptors to more fully understand the importance of compound structure and binding to influence nuclear estrogen receptor interactions, and its role in stimulating estrogenic responsiveness. (2) Analyze the biochemical and molecular properties of the estrogen receptor proteins to determine what signaling processes are involved in their activation and role in biological responses. Evaluate the specificity of the estrogen receptor forms (α and β) on activity and the transcriptome profiling of various environmental compounds. (3) Investigate the expression of estrogen response in uterine and other hormonally responsive tissues and evaluate the involvement of the receptor signaling pathways in the mechanism of tissue stimulation. Such understanding will form a basis towards comparison to different disease states of the tissue(s) regarding toxicity, carcinogenesis and/or functional phenotypic alterations and susceptibilities to disease.
