Short Bio: 

Dr. Nagle is a Professor Emeritus of Pathology, Cell Biology and Anatomy, and Surgery at The University of Arizona, and former medical director at Ventana Medical Systems in Tucson, Arizona. He previously served as Deputy Director (1997-2003) and Interim Director (2003-2005) of The University of Arizona Cancer Center.

From 2001-2014 he served as the Director of the Tissue Acquisition and Cellular/Molecular Analysis Shared Resource (TACMASR), which is part of the University of Arizona Cancer Center Core Grant.

His major research interests involve molecular pathology studies in prostate carcinogenesis. His research program has focused for the past several years on understanding the biological basis for the variability in the clinical evolution and spread of prostate cancer. In collaboration with Drs. Anne Cress, Timothy Bowden, Ronald Heimark and many others, his group has worked to define molecular events during the progression of the disease that allow the cancer to migrate out of the site of origin in the prostate and thus metastasize to the bone and other sites. Such knowledge may provide the basis for predicting the probable outcome of an individual’s tumor as well as suggest approaches to block the evolution and dissemination of prostate cancer.

His current research interests continue to explore factors involved in early prostate cancer invasion. His research has previously described that through a process of collective invasion, genetically unstable cells found in PIN lesions invade the prostate stroma. In this process the invasive cells maintain cohesion and are surrounded by an altered basal lamina containing laminins 10 and 11, but deficient in laminin 5. Recent work has described translational control of the three chains of laminin 5 as well as its receptor integrin β4 by miRNA 205 which in turn is regulated by miRNA 184.  They are currently investigating the role of these molecules in prostate cancer invasion using clinical material as well as cell lines.

Dr. Nagle received combined training in anatomic and clinical pathology at the University of Washington. Subsequently, he received an NIH post-doctoral fellowship in experimental pathology which led to a Ph.D. degree. He was an associate pathologist in the Department of Experimental Pathology at Walter Reed Army Institute of Research where he was involved in studies of pathogenesis of African Trypanosomiasis as well as acute renal failure. Following military service, he served on the faculty at the University of Maryland where his research primarily dealt with mechanisms of acute renal failure as well as models of experimental glomerulonephritis. In 1968 he joined the faculty at the University of Arizona College of Medicine. His work as a surgical pathologist led to a research program focusing on the role and identification of cytokeratins in the diagnosis of human neoplasms.

Dr. Nagle has administered over 28 funded research grants, and authored over 250 peer-reviewed papers and abstracts in the area of solid tumor pathology and prostate cancer progression.
