BAR HARBOR, ME, UNITED STATES – Nov 30, 2018 – Vicki P. Losick, Ph.D., has been named the inaugural recipient of an award from the William Procter Scientific Innovation Fund. The award will support her research at the MDI Biological Laboratory on age-related macular degeneration (AMD), a leading cause of vision loss in older people.
The Procter Fund was established at the MDI Biological Laboratory earlier this year by a member of William Procters family in honor of his achievements in science and business. Procter was the grandson of William Procter, the founder of Procter & Gamble (P&G), and an active member of the P&G board until his death in 1951.
In recognition of Procters interest in translating science into applications to improve human health and quality of life, the fund provides up to $50,000 annually to support high risk/high impact research, basic research with potential for commercialization and education programs focused on translating discoveries into commercial applications.
Losicks high risk/high reward project, which was selected by an external review committee, will establish a fruit fly model that mimics the cellular dysfunction associated with human retinal diseases, including AMD. She will use the model to study the genetics underlying the disease, and potentially to test for interventions to prevent or reverse it.
The development of treatments for AMD has been challenged by the fact that the underlying cellular dysfunction takes years to manifest in mouse models and decades in humans. Since such cellular dysfunction takes only weeks to arise in the short-lived fruit fly, it could serve as an inexpensive and efficient platform for the study of the disease.
With the aging of the population, age-related macular degeneration is increasingly being viewed as an impending epidemic, Losick said. I am deeply grateful to the Procter Fund for supporting research that could lead to the identification of the genetic and cellular causes underlying retinal dysfunction.
The award to a scientist who studies the fruit fly is especially fitting given the fact that Procter was a graduate student in zoology at Columbia University, where he was inspired by Thomas Hunt Morgan, the Nobel-prizewinning scientist who founded modern genetics and established the fruit fly as a model for the study of human disease.
Procter went on to become a prominent entomologist and the author of a Biological Survey of the Mount Desert Region, an exhaustive, seven-part survey of the insect and marine fauna of Mount Desert Island that was launched in the 1920s at the MDI Biological Laboratory, where he served as a trustee and as president.
Losicks research on AMD is an outgrowth of her earlier work on wound healing in which she found that extra-large cells called polypoid cells maintain the size and function of injured tissue. In 2017, she was recognized as an outstanding investigator by the National Institutes of Health(NIH) for this research.
In the eye, however, the presence of these extra-large cells in the retinal epithelium sets the stage for AMD. Losicks goal is to identify the role played by polyploidy in AMD and, in collaboration with Patsy Nishina, Ph.D., an expert on retinal diseases at The Jackson Laboratory, identify genetic or pharmacological strategies to treat it.
The fruit fly is a novel model for AMD because the generation of polyploid cells in its abdominal epithelium mimics that of these cells in the human retinal epithelium. Since the fruit fly shares many of its genes with humans, an increased understanding of the genes governing polyploidy could open the door to new therapies for AMD.
Losick, who joined the MDI Biological Laboratory in 2016, has established herself as a leader in research on the role of polyploidy in wound healing and aging. In October 2018, she led a first-of-its kind conference at the MDI Biological Laboratory on Polyploidy in Organ Development, Repair and Disease.
About the MDI Biological Laboratory
We are pioneering new approaches to regenerative medicine focused on developing drugs that slow age-related degenerative diseases and activate our natural ability to heal. Our unique approach has identified potential therapies that could revolutionize the treatment of heart disease, muscular dystrophy and more. Through the Maine Center for Biomedical Innovation we are preparing students for 21st century careers and equipping entrepreneurs with the knowledge, skills and resources needed to turn discoveries into applications that improve human health and well-being.
