We hypothesize that progestins and vitamin D both target the early steps of carcinogenesis in the endometrium by clearing genetically damaged endometrial glandular cells, resulting in effective cancer prevention. In addition, we hypothesize that the combination of a progestin and vitamin D will be more effective for endometrial cancer prevention than either agent administered alone. Our goal is to develop this combination for endometrial cancer prevention. To achieve this end, we propose the following: to elucidate the molecular mechanism(s) underlying the synergistic interaction of progestins and vitamin D in the endometrium, directly test the endometrial cancer preventive efficacy of a potent progestin, vitamin D, and the combination of a progestin and vitamin D in vivo in a prospective trial using PTEN heterozygote mice which have been shown to be prone to develop endometrial hyperplasia and cancer, to examine the impact of progestin and Vitamin D exposure, and their interaction, on endometrial cancer risk in a population based study (Nurses Health Study), and to demonstrate that progestin and vitamin D activate surrogate endpoint biomarkers relevant to chemoprevention in the endometrium in a prospective randomized trial in women undergoing hysterectomy for benign indications.
The overall goals of the University of Pittsburgh Skin Cancer SPORE are to improve the prevention and treatment of skin cancers, focusing upon melanoma and cutaneous T cell lymphoma. The SPORE program will consist of five translational research projects in skin cancer, four cores including an administrative core, a developmental research program and a career development program. The University of Pittsburgh Skin Cancer SPORE will use an interdisciplinary approach to meet its objectives by carrying out projects with co-investigators in basic, applied and clinical science. It is also organ-specific in that its approach and all projects will test hypotheses about skin cancer molecular biology and progression, tumor immunobiology and treatment. The long-term translational research projects will serve as the basis for improving the outcome of patients with lethal skin cancers
