Dr. Hill received his B.S. in Biology from Abilene Christian University in 1980. He conducted his doctoral studies on the cellular mechanisms of the pineal hormone on growth of human breast cancer under the tutelage of Dr. David E. Blask at the University of Arizona, obtaining his Ph.D. in 1986. From 1986 to 1988 Dr. Hill was a postdoctoral fellow with the late Dr. William L. McGuire at the University of Texas Medical Center at San Antonio, working on the molecular mechanisms of estrogen-resistance in human breast cancer. In 1988 Dr. Hill returned to Abilene Christian University where he taught Anatomy/Physiololgy, Cell Biology, and Developmental Biology. In 1989 Dr. Hill joined Tulane University Health Sciences Center in the Department of Structural and Cellular Biology, where he is the course director for Medical Embryology. Dr. Hill has published over 60 manuscripts and book chapters in the area of molecular endocrinology and breast cancer. He is a reviewer for a variety of journals including Cancer Research, Breast Cancer Research and Treatment, and Molecular Endocrinology and has served on NIH, DOD, and NSF grant review panels. The primary focus of Dr. Hill's research is the molecular mechanisms of signal transduction cross- talk in breast cancer. Breast cancer is an endocrine-responsive neoplasm and as such is responsive to a variety of endocrine and growth factor stimuli. A complete understanding of the factors regulating the proliferation breast cancer, as well as an understanding of how these various hormones and factors cross-talk with each other to regulate breast cancer cell growth, is crucial to development of more potent breast cancer therapies. Dr. Hill's laboratory has conducted extensive studies examining the role of mutated estrogen receptors in the development of an estrogen-insensitive/tamoxifen-resistant phenotype in breast cancer. They have identified variant forms of the estrogen receptor that can function independent of hormone stimulation and can act to constitutively drive the mitogenic estrogen-response pathway in breast cancer. More recently, Dr. Hill's laboratory has demonstrated that the pineal hormone melatonin has significant inhibitory effects on the development and growth of human breast cancer. Furthermore, their studies have elucidated that melatonin can potentiate the actions of retinoic acid, a vitamin A derivative, to induce cell death in human breast tumor cells in culture, to prevent the development of carcinogen-induced breast cancer in rats and to induce the regression of over 70% of established breast tumors in rats. These studies currently are being moved into human clinical trials. Finally, Dr. Hill, in collaboration with investigators at Tulane Cancer Center and Xavier University, is examining the cross-talk of signaling pathways such as the melatonin receptor with the retinoic acid receptor and estrogen-receptor in both breast and prostate cancer and how these pathways can be manipulated to provide enhanced therapeutic advantage.

2000 Percival Stern Hall, Tulane University, New Orleans, LA 70118

Biographical Narrative:
Dr. Hopkins received her B.S. in chemistry from Auburn University in 1970 and an M.S. in clinical pathology from the University of Alabama at Birmingham in 1973. After teaching at Loyola University in New Orleans for several years, she entered the doctoral program in the Chemistry Department at Tulane University in the laboratory of Dr. William Alworth and received her Ph.D. in 1992. She moved to the laboratories of Dr. William George and Dr. Juan Lertora in the Pharmacology Department at Tulane University School of Medicine. Her research interests are centered on the role of cytochrome P450 in both carcinogenesis and cancer chemoprevention. She is also interested in the role of natural products that are chemo-preventive in breast and prostate cancer. In collaboration with Dr. Maryam Foroozesh at Xavier University, she studies the inhibition of cytochrome P450 and the Akt pathway by natural product analogs. Dr. Hopkins is a member of the American Association of Cancer Researchers, the American Chemical Society, and the American Society of Biochemistry and Molecular Biology. She is also an associate member of the Society of Toxicology. She is on the National Council of Iota Sigma Pi Women's Chemistry Honorary Society.
