Our research efforts have a dual focus 1) prevention of ovarian aging and chemotherapy and other ovarian toxicant induced infertility 2) prevention of breast and ovarian cancers through the characterization and antagonism of promising targets in human and animal chemoprevention trials. Early work showing ovarian follicular loss in polluted environments (i.e. dioxin) mediated by the aryl hydrocarbon receptor was the underpinning for later work indicating that tamoxifen may protect against follicular loss from alkylating agent chemotherapy. I was recruited to the Department of Medicine, Division of Hematology/Oncology in 2004 to collaborate on translational aspects of early prevention trials in breast and ovarian cancer. This included development of the first model of nearly simultaneous ER+ breast and ovarian pre-cancer which would be invaluable in assessment of risk and mechanism of action biomarker modulation for Phase II human prevention trials. In this manner investigators would be able to preview the effects of an intervention on the ovary as well as breast in a model which is hormonally analogous to a late premenopausal woman. During the validation of this model with the Selective Estrogen Receptor Modulator (SERM), tamoxifen, it was noted that tamoxifen could protect against carcinogen (DMBA) induced ovarian follicle loss and hence aid in preserving fertility. The observations were repeated for cyclophosphamide. The breast and ovarian cancer model itself is being used in a multi-PI multi-project Komen Promise Grant awarded in 2010. I have been instrumental in overseeing the development of more advanced molecular techniques to characterize biomarker change in breast chemoprevention trials from the small amounts of material available from random peri-aerolar fine needle aspirations including proteomics and stem cell markers, lipidomics, hormone measurements and gene expression after and laser capture micro-dissection. I have held a leadership position in the developing University of Kansas Cancer Center as coleader of Cancer Prevention since 2008.
