Barbara Maker Vertel, PhD
Dr. Vertel received her BS degree in biology from Cornell University in 1968 and her PhD in biology from the University of Chicago in 1974. Her postdoctoral research was conducted in the Departments of Biochemistry and Pediatrics at the University of Chicago. Dr. Vertel was an Assistant Professor of Biology at Syracuse University from 1980 to 1986 and at SUNY Upstate Medical Center at Syracuse from 1985 before joining the faculty of the Chicago Medical School as an Associate Professor in 1987. She was later awarded tenure, and in 1994 was promoted to full Professor. Dr. Vertel’s research concerns the formation of extracellular matrix, particularly in cartilage. Emphasis is placed on intracellular trafficking and quality control in health and disease. For over 30 years, her research received funding from the NIH and the Arthritis Foundation.
Extracellular matrix formation in cartilage has been the main subject of Dr. Vertel's research. The emphasis on intracellular events in subcellular compartments reveals underlying mechanisms for the synthesis, processing and quality control of cartilage matrix molecules and other secreted or membrane proteins in normal cells, and as the basis of disease. Immunohistochemical, biochemical, and molecular approaches are used in conjunction with live cell imaging to develop a broad view. Immunolocalization at the levels of light and electron microscopy is used to visualize coordinate biosynthesis and matrix deposition, while biochemical studies provide complementary information about processing and biosynthetic intermediates of matrix molecules. Transfection experiments utilizing genetic constructs are combined with live cell imaging studies of GFP-tagged versions of the proteins. Specific attention has been directed to models of chondrodysplasias and cataracts.
