Background

Dr. Angelo De Marzo is a professor of pathology, oncology and urology at the Johns Hopkins School of Medicine. His areas of clinical expertise include pathology and prostate cancer. Dr. De Marzo serves as the associate director of Cancer Research Pathology at the Sidney Kimmel Comprehensive Cancer Center.

Dr. De Marzo founded the Tissue Microarray Core at Johns Hopkins, now known as the Oncology Tissue Services. He led it for a decade and now serves as an advisor to the core.

Dr. De Marzo's research interests include the molecular pathobiology of prostate cancer, biospecimen banking, biomarker development and tissue microarrays.

Dr. De Marzo received his B.A. in molecular, cellular and developmental biology and psychology from the University of Colorado at Boulder. He earned his M.D. and Ph.D. in experimental pathology from University of Colorado Health Sciences Center. He completed his residency in pathology at the Johns Hopkins School of Medicine and performed a fellowship at the Brady Urological Institute at Johns Hopkins. Dr. De Marzo joined the Johns Hopkins faculty in 1998.

Dr. De Marzo is Chief Medical Officer at Predictive Biosciences Inc., and serves on the editorial board of The Prostate and Cancer Prevention Research. He is the recipient of the 2004 Donald S. Coffey Prostate Cancer Foundation Physician/Scientist Award and is a member of various professional organizations, including the American Urological Association and the American Association for Cancer Research.

Research Summary

Dr. De Marzo’s research focuses on prostate cancer, paying special attention to prevention. His research group has postulated that a common lesion often associated with inflammation—called proliferative inflammatory atrophy (PIA)—may represent a risk factor or precursor lesion to prostate cancer. This research has implications for prevention and chemoprevention of prostate cancer.

Dr Marzo’s laboratory is also using genetically engineered mouse models and cell culture systems to study the role of the MYC oncogene in prostate cancer cell neoplastic transformation and cell growth regulation. Since MYC is a key regulator of stem cells, these studies have direct implications for stem cell models of prostate cancer formation.

Additionally, the laboratory also has been leading efforts to apply novel biomarkers to human prostate tissues, to provide tissue banking for the prostate cancer research program, and to develop tissue microarrays and tissue microarray software.

Lab

Dr. De Marzo's laboratory is focused on developing new insights into the molecular pathobiology of prostate cancer. For example, they are focused on determining the cell type of origin and the molecular mechanisms involved in neoplastic transformation in the prostate.

His laboratory performs translational research to interrogate biomarker expression in human prostate tissues, where such biomarkers might aid the pathologist in making a diagnosis on challenging biopsy cases, help to predict outcome, help determine whether a given pathway alteration is present, or help to determine whether a drug has hit its target.

Additionally, Dr. De Marzo's lab is involved in tissue banking, tissue microarray technology, tissue microarray software and database design, and image analysis of tissue microarrays.

Dr. De Marzo's laboratory works very closely with the labs of William G. Nelson M.D., Ph.D., Srinivasan Yegnasubramanian M.D., Ph.D. and Karen Sfanos Ph.D. in a number of related research areas. The lab also collaborates extensively with Alan K. Meeker Ph.D., and Elizabeth Platz Sc.D. PSD, from the Johns Hopkins Bloomberg School of Public Health, and a range of other investigators both within and outside of Johns Hopkins.
