Dr. Belldegrun is internationally recognized in the field of surgical and medical management of urological cancers, designing and conducting large-scale clinical trials, and in the development of innovative therapies for patients with localized and metastatic kidney, bladder, and prostate cancer. Dr. Belldegrun’s research laboratory at UCLA has been a pioneer in the fields of genetic cancer therapy, immunotherapy, cancer vaccines, and targeted molecular therapy for urological malignancies.
Dr. Arie Belldegrun's research focuses on targeted specific therapy and immunotherapy of kidney and prostate cancers. Belldegrun's laboratory reported on the cloning of a tissue specific and androgen responsive novel 620 bp PSA promoter sequence and upstream sequence. The enhanced gene expression of the resulting construct, combined with its tissue specificity and androgen responsiveness, provide the foundation for the development of tissue specific vectors for prostate cancer gene therapy.
Belldegrun's laboratory also has studied the feasibility of isolating functional dentrictic cells from the peripheral blood of renal cell carcinoma patients and has compared their transduction efficiency using various methods of transferring gene markers into dentritic cells.
Arnold Chin, M.D., Ph.D, is a physician-scientist dedicated to improving the lives of patients with urologic malignancies. Focused on bladder and prostate cancer, his research team studies how the immune system recognizes and modulates cancer growth, invasion, and metastases.
Current projects include understanding the mechanisms that distinct immune pathways use to regulate tumor growth and spread, which will be important in identifying targets for novel immune-based therapies. A second area is focused on understanding bladder cancer stem cells, which may be the origin of the cancer. These cells may be resistant to current therapies. Targeting the cancer stem cell population, the team is studying the molecular and genetic mechanisms and is developing a personalized therapy program for bladder cancer patients to match specific treatments with patients. Chin hopes his studies will determine which tumors may respond to specific treatments and design novel therapeutics that optimize the body’s own immune system to fight cancer.
Dr. Isla Garraway is the Principal Investigator of a basic science laboratory in the Jonsson Comprehensive Cancer Center. Her current projects are focused on human prostate stem cells and prostate tumor-initiating cells, as well as development of human prostate tumor models. Specifically, Dr. Garraway is developing ways to isolate specific stem cells from patients with prostate cancer.
These cells likely constitute a small fraction of all cells in the prostate, and have the unique ability to regenerate themselves. Understanding what role stem cells play in cancer tumor growth could prove to be monumental in developing future targeted therapies for prostate cancer patients.

Robert Reiter, MD, MBA, is a Professor of UCLA Urology, Chief, Division of Urologic Oncology and Director, UCLA Prostate Cancer Program. He is currently the Principal Investigator of UCLA’s SPORE (Specialized Program in Research Excellence) program, a 12 million dollar multifaceted research program that strives to translate basic science advances in prostate cancer to the management of men with this disease. There are currently only 8 active Prostate Cancer SPORE programs in the United States, of which UCLA’s is the only such program in California. In addition, Dr. Reiter is only one of two urologists who lead such programs in the country. In addition to the SPORE grant, Dr. Reiter has won numerous awards and honors, including the Stop Cancer Young Investigator Award, the Society for Urologic Oncology Young Investigator Award, and election to the American Society for Clinical Investigation. His work has been funded continuously for 14 years by the National Cancer Institute, the American Cancer Society, the Department of Defense, the New York Academy of Medicine, the Margaret Early Trust and other funding agencies.
His research group has two main areas of laboratory and clinical investigation, the common denominator being the application of basic research and new technologies to the management of prostate cancer.
First, we are focused on understanding the fundamental mechanisms that lead to prostate cancer metastasis and progression to castration resistance (in which prostate cancers become resistant to testosterone inhibition using drugs such as Lupron, Enzalutamide and Abiraterone). In particular, we are developing novel therapies to intervene in these pathways of resistance. These include development of antibody therapies that we are hoping to take into the clinic. These also includes the use of approved cancer drugs in clinical trials of men with high risk and metastatic prostate cancers.
Second, we are focused on improving the ability to detect prostate cancer in patients using PET (positron emission tomography), MRI, and other forms of imaging. We have made major contributions in the development of MRI to diagnose and manage prostate cancer, being among the first to use this technology to plan and perform robotic surgery. In the laboratory, we have developed novel probes (proteins or small molecules that can hone in on prostate cancers anywhere in the body and enable visualization/detection by PET scans) for PET and other imaging. Specifically, we developed antibody scaffolds called minibodies that can detect prostate cancer proteins such as PSCA (prostate stem cell antigen) and PSMA (prostate specific membrane antigen). In addition, we are developing methodologies to see prostate cancers during surgery using fluorescent probes, a major unmet need.

Dr. Rettig has both a clinical and bench research program. As the director of the clinical trials program in prostate cancer at UCLA, he conducts multiple prostate cancer clinical trials that span the spectrum of the states of the disease: from neoadjuvant therapies to post-chemotherapy, castration-resistant disease. Dr. Rettig’s bench research program, which is funded by the NIH, Department of Defense and the Department of Veterans Affairs, is focused on identifying biochemical targets for therapeutic translation in castration-resistant prostate cancer and clear cell renal cell carcinoma.
Dr. Christopher Saigal’s research is focused on the nexus of quality of care and trends in medical technology. The Urologic Diseases in America project, an ongoing, NIH-funded research enterprise, evaluates quality, cost, and technology trends in major urologic conditions such as prostate, kidney and bladder cancer, as well as benign diseases such as benign prostatic hyperplasia and kidney stones. Over 60 policy-relevant manuscripts have resulted from this project. Other major research efforts involve finding ways to use technology to improve decision making for patients in the setting of localized prostate cancer. Specifically, this research tests ways to improve “shared decision making” using computer applications. Dr. Saigal also leads the UCLA site for two national NCI-funded trials to examine outcomes of care in men treated for localized prostate cancer.
Dr. Saigal’s research is currently funded by the National Institutes of Health, National Cancer Institute and the Lance Armstrong Foundation.
Dr. Gang Zeng’s ongoing research involves dendritic cell (DC)-targeting prostate and kidney cancer vaccines, as well as A+PSA technology for improved prostate cancer diagnosis and risk assessment.
Dendritic Cell (DC)-Targeting Prostate and Kidney Cancer Vaccines: DC-based vaccines have shown encouraging results in treating castration resistant prostate cancer. However, most DC vaccines require tedious and costly manipulations ex vivo. More potent cancer vaccines capable of targeting immature DC in vivo and bypassing the ex vivo manipulations, are critically needed. The presence of DC surface receptors for a new class of damage-associated molecular patterns indicated novel approaches for DC-targeting in vivo. This project addresses the immunological and anti-tumor effects of DC-targeting vaccines using the myc-CAP prostate cancer and Renca kidney cancer models.
A+PSA technology for improved prostate cancer diagnosis and risk assessment:We have developed a novel multiplex assay that simultaneously measures auto-antibodies and PSA in a single reaction (termed the A+PSA assay). This new technology is being investigated for aiding prostate cancer diagnosis with reduced unnecessary biopsies as well for predicting lethal from indolent prostate cancers with reduced overtreatment.
Dr. Zeng’s research is currently funded by the National Institutes of Health, American Cancer Society, Neuberger Berman Foundation and the Dr. Susan Love Breast Cancer Foundation.
