Melanoma Genetics
Professor, University of Cincinatti
Dr. Abdel-Malek's research is focused on investigating the function of the melanocortin 1 receptor (MC1R), its agonists α-melanocyte stimulating hormone (α-MSH) and ACTH, and antagonists agouti signaling protein and human β-defensin 3 in regulating cutaneous pigmentation and the response to UV radiation. Her lab was among the first to demonstrate that human melanocytes express functional MC1R and that activation of this receptor is critical for the melanogenic (i.e. tanning response) to UV.
Assistant Professor, OHSU Department of Dermatology
Director, Multidisciplinary Pigmented Lesion Clinic
Dr. Berry has dedicated her career to treating patients with melanoma and those who are at high risk for the disease. She chose the field of dermatology because she believes that early detection of skin cancer is the best chance for a cure. Along with seeing patients, Dr. Berry has research interests in better understanding genetic risk factors for melanoma and future technologies that will better allow clinicians to identify skin cancers.
Professor and Chair , OHSU Dermatology
Director, Melanoma Program, OHSU Knight Cancer Institute
Dr. Leachman’s research interest is in the prevention, early detection and chemoprevention of melanoma, particularly in genetically predisposed melanoma families. One arm of her research program examines the role of genetic predisposition and differential gene expression in the development of melanoma, with an emphasis on familial melanoma and other cutaneous cancer syndromes. Through collaborations with Dr. Cassidy, she seeks to develop agents that will serve as diagnostic tools, prognostic indicators or targeted agents for the prevention of melanoma.
Associate Professor, The University of Queensland, AU
Dr. Rick Sturm is group leader for Molecular Genetics of Pigmentation research at the Institute for Molecular Bioscience at the University of Queensland in Australia. His team's work on human pigmentation genetics has allowed understanding of normal variation in this physical trait and the associated genotypic risk for skin cancer. The genes that determine an individual's skin phototype and the cellular mechanisms that result in the tanning response of melanocytes after UV-exposure of the skin are actively being investigated.
Assistant Professor, University of Utah
Dr. Wu's ongoing research studies include testing new behavioral interventions to promote implementation of cancer prevention behaviors among children and their families, particularly to prevent skin cancer. The goal of this work is to support youths and their families in understanding their risk for cancer or other undesired health outcomes and in carrying out behaviors that will promote their health.
The Utah Population Database (UPDB) at Huntsman Cancer Institute at the University of Utah is one of the world’s richest sources of in-depth information that supports research on genetics, epidemiology, demography, and public health. Since the mid 1970s, researchers at the University of Utah and other institutions have used UPDB to identify and study individuals and families that have higher than normal incidence of cancer or other diseases, to analyze patterns of genetic inheritance, and to identify specific genetic mutations. In addition, demographic studies have shown trends in fertility transition and changes in mortality patterns for both infants and adults.
Our genetics and molecular pathology laboratories were merged into one laboratory operation under the Knight Cancer Institute in January 2011. Specializing in oncology, rare genetic disorders, and infectious disease, the laboratories are CLIA certified and CAP accredited. Our Medical Directors and seasoned technical staff have many years of experience in clinical testing and test development and are dedicated to providing the best quality service for physicians and their patients.
Through our close partnership with the Knight BioLibrary and Histopathology Shared Resource Laboratories, research investigators can gain access to human biological specimens, histology, and immunohistochemistry services.

Melanoma Tissue Bank Consortium
The Melanoma Tissue Bank Consortium aims to collect more than 500 fresh-frozen primary melanoma tissue samples, additional biospecimens (blood, urine, etc.) and corresponding patient data in order to support melanoma research. These well-annotated samples, which will be available to researchers anywhere in the world, will help to answer critical research questions related to melanoma epidemiology, etiology, and treatment.
The AIM at Melanoma Foundation funds this effort AIM has brought together six esteemed institutions and researchers to establish the world’s first collaborative melanoma tissue bank consortium.
