Dr. William B. Isaacs is a professor of urology and oncology at the Johns Hopkins School of Medicine. He is the William Thomas Gerrard, Mario Anthony Duhon and Jennifer and John Chalsty Professor of Urology. His primary research focus is hereditary prostate cancer.
Dr. Isaacs’ team is working to characterize consistent alterations in the structure and expression of the genome of human prostate cancer cells as a way to identify genes that are critical in the pathways of prostatic carcinogenesis. The goal of this research is to more effectively identify men at high risk for prostate cancer and to identify new prognostic and therapeutic markers that could lead to more effective management of this common disease.
Dr. Isaacs completed his undergraduate degree at Brown University and joined the Johns Hopkins staff as a lab technician for Donald Coffey, then director of the Brady Urological Research Laboratory. He received his doctorate from Johns Hopkins University in the Department of Pharmacology and Molecular Science. He left Hopkins to do a post-doctoral program at the University of Iowa, and returned in 1988 to join the faculty of the Department of Urology.
Dr. Isaacs is recognized as a leader in the field of hereditary prostate cancer research. He has won numerous national and international awards and is a member of Sigma Xi, the American Society for Cell Biology, the Society for Basic Urologic Research and the American Association for Cancer Research.

Research & Publications
Dr. Isaacs’ lab is working to characterize consistent alterations in the structure and expression of the genome of human prostate cancer cells as a means of identifying genes critical in the pathways of prostatic carcinogenesis. They are focusing on somatic genomic alterations occurring in sporadic prostate cancers, as well as germline variations that confer increases in prostate cancer risk. Both genome wide and candidate gene approaches are being pursued, and cancer associated changes in gene expression analyses of normal and malignant prostate cells are being cataloged as a complementary approach in these efforts.
As an approach to identify high-risk prostate cancer susceptibility alleles, the lab has identified a large number of families having multiple men affected with prostate cancer. Linkage analysis in these families has provided evidence of susceptibility genes located on chromosomes 1 and 8; RNASEL (1q24-25) and MSR1 (8p22) have been identified as candidate prostate cancer susceptibility genes on these chromosomes. The involvement of these genes in the innate immune system suggests an important role for genetic variability of host response in determining individual prostate cancer risk. Current efforts are aimed at characterizing the role of these genes in prostate carcinogenesis, and the identification of additional prostate cancer gene loci.
It is anticipated that this work will assist in providing more effective methodologies to identify men at high risk for this disease in general, and in particular to identify new markers of prognostic and therapeutic significance that could lead to more effective management of this common disease.
