Salmon and other freshwater fish and amphibians supercharge their ability to see red and infrared light. Scientists at the School of Medicine have shown that this evolutionary adaptation hinges on the activity of an enzyme that converts vitamin A1 to vitamin A2, enabling the aquatic creatures to more easily navigate murky waters.
Joseph Corbo, PhD, MD, of Washington University School of Medicine in St. Louis, received research grants from the McDonnell Center for Cellular and Molecular Neurobiology and from the Washington University Intellectual and Developmental Disabilities Research Center.
Joseph Corbo, MD, PhD, associate professor of pathology and immunology, of genetics and of ophthalmology and visual sciences, has received a one-year, $25,000 grant from the Center for the Investigation of Membrane Excitability Diseases for research titled “High-Throughput Functional Analysis of Non-Coding Regions Related to Arrhythmias.”
Faculty members manned posters highlighting their research at a recent Division of Biology and Biomedical Sciences event geared toward helping graduate students meet faculty and learn about research before signing up for laboratory rotations. The event is an engaging step for students earning their PhDs or MD/PhDs through the Medical Scientist Training Program. Pictured is student Allyson Mayer visiting with Carlos Bernal-Mizrachi, MD, at the event.
Doctors may one day treat some forms of blindness by altering the genetic program of the light-sensing cells of the eye, according to School of Medicine scientists. Working in mice with a disease that causes gradual blindness, the researchers reprogrammed the cells in the eye that enable night vision.
