Edward Brown's research is a mixture of photonics, microscopes and a little nudge from his mom.
Brown, who teaches biomedical engineering at the University of Rochester Medical Center, has built a laser-and-microscope device to study how likely cancer cells will spread throughout the body. Specifically, he's looking at how likely cancer cells have spread inside breast cancer patients who already have had the tumor removed.
Learning more about the cell movement, called metastasis, is key to a larger overtreatment problem that Brown is trying to fix.
When patients first realize they have breast cancer, it's unclear whether the cancer cells have spread, so doctors recommend chemotherapy as a precaution. However, Brown and other medical researchers believe patients are being overtreated because doctors are giving chemo to patients who may not need it.

Ed Brown Awarded Department of Defense Grant
Dr. Edward Brown (BME) has received a $140k grant from the Department of Defense Breast Cancer Research Program for his project entitled
Prediction of Metastasis Using Second Harmonic Generation.The goal of this one year project is to expand upon a recent finding from Dr. Brown's laboratory that an optical scattering phenomenon called second harmonic generation (SHG), when applied to breast cancer biopsy specimens, can help predict metastatic outcome in 10-year patient follow-up data.
This has significant clinical implications because current data suggests that about half of patients that are systemically treated after their tumor is removed would not have experienced a metastasis, did not need to suffer the toxic effects of systemic therapy, and therefore were
overtreated. Hence there is a pressing need to predict who will, and will not, experience metastasis, to minimize overtreatment. The current work, conducted in collaboration with Dr. Peter Salzman (Biostatistics), Dr. Ping Tang (Pathology), and Dr. Kristin Skinner (Surgery), will validate their recent findings in a second patient cohort and determine the most powerful predictive formula incorporating SHG signatures as well as other clinical data.

Kelley Madden Receives 2-year DOD IDEA Expansion Grant
Kelley S. Madden, Ph.D., Research Assistant Professor in Edward Brown's lab, in the Department of Biomedical Engineering has received a 2-year DOD IDEA Expansion Grant worth $575,000 for her project entitled, Alpha2-Adrenergic Receptors and Breast Tumor Stroma: A Novel Pathway Driving Breast Cancer Growth and Metastasis. The project is based on the stress neurotransmitter norepinephrine which promotes breast tumor progression and metastasis. The grant will investigate how selective activation of one of the receptors for norepinephrine, the alpha2-adrenergic receptor, impacts tumor stromal cells and their modulation of the tumor extracellular matrix to promote tumor metastasis. The proposed research may lead to new therapies to treat metastatic breast cancer by targeting alpha2-adrenergic receptors.

Neuroscience graduate student, Ryan Dawes, has been awarded a 2013 Breast Cancer Research Grant, from the Breast Cancer Coalition of Rochester. The 1-year, $50,000 grant will fund his project, entitled Breast Cancer Exosomes, Novel Intermediaries in Psychosocial Stress-induced Tumor Pathogenesis and was only one of two applications to be awarded this prestigious grant. This work will investigate if psychosocial stress can modulate the number or content of secreted small vesicles (exosomes), and determine if this can alter the process of tumorigenesis in an animal model of spontaneous breast cancer as Ryan continues his research in Dr. Edward Brown's lab.

Dr. Kelley Madden Receives Department of Defense IDEA Award
Dr. Kelley Madden has received funding from the Department of Defense Breast Cancer Research Program for a 2-year study that seeks to understand how an important stress pathway, the sympathetic nervous system, influences breast tumor growth and metastasis. Specifically, this study will determine if the sympathetic nervous system encourages growth of blood vessels into a tumor (angiogenesis). A unique aspect of this project is to determine if the sympathetic nervous system alters the effectiveness of therapy targeting and destroying tumor blood vessels (antiangiogenic therapy). Understanding how a stress pathway influences tumor growth will open the door to therapeutic options targeting the sympathetic nervous system. Importantly, therapies targeting sympathetic nervous system signaling pathways are already in use in the clinic for safe, chronic treatment of heart disease, offering the possibility of rapid clinical application of our findings. This project continues work that has been previously funded by the Breast Cancer Coalition of Rochester.

MD/PhD Student Mercedes Szpunar Receives a DoD Breast Cancer Research Program Predoctoral Fellowship
Mercedes Szpunar, an MD/PhD student in the laboratory of Dr. Edward Brown, has received a Department of Defense Breast Cancer Research Program predoctoral fellowship. This fellowship, which supports up to three years of graduate stipend and travel funds, funds her thesis project focused on the effects of chronic stressor exposure on breast cancer growth. This study seeks to delineate how stress hormones alter tumor cell signaling, thereby promoting tumor growth and metastasis. Utilizing human breast cancer cell lines, the project includes in vitro and in vivo experiments and the optical technique of Second Harmonic Generation (SHG) - to image the ordering of collagen fibers – to determine changes in tumor progression in the setting of chronic stress.

Dr. Edward Brown Receives an NIH Director's New Innovator Award
Dr. Edward Brown has received an NIH Director's New Innovator Award to support a 5 year/$1.5M study that seeks to understand the cells and signals responsible for collagen organization in tumor-draining lymph nodes (TDLNs). This study exploits an optical phenomenon called Second Harmonic Generation (SHG) which allows for the microscopic imaging of ordered collagen fibers within living tissue. Tumor cells can exploit these ordered fibers during metastasis, and Dr. Brown hopes to determine the cells and signals which influence the SHG+ fibers in order to disrupt their production and inhibit metastasis via the TDLN, which is a primary route. He will also explore the ability of SHG imaging of TDLN biopsies to predict metastatic ability, to aid in customization of postoperative therapy. This project continues work that has been previously funded by a D.o.D.
