Dr. Robert Moore, Senior Scientist, University of Wisconsin, School of Pharmacy has studied the effects of dioxin exposure on reproductive systems for a large part of his career as an academic researcher. This focus led him to consider the role of dioxin exposure in the development and aging of the prostate. He has discovered that gestational dioxin exposure causes persistent changes in the prostate gland, which are believed to constitute precancerous lesions. In delving into the molecular biology of this phenomenon, he has learned that the aryl hydrocarbon receptor inhibits prostate carcinogenesis. Dr. Mooreâs current research seeks an answer to the question of whether or not gestational dioxin exposure predisposes offspring to increased prostate cancer susceptibility.
