We are examining a molecule called GAP-43 which is a brain protein that is expressed in a wide variety of species including humans and has been shown to become biochemically altered in the process of learning and memory.  Specifically, levels of phosphorylated forms of GAP-43 have been shown to increase following a controversial paradigm of learning and memory in several animals including rat, mouse and rabbit.  We are interested to see if any differences in the profile of GAP-43 are associated with dementing illnesses that severely disrupt memory and learning.  Since human brain tissue is difficult to obtain, we utilize brain tissue from a genetically altered mouse engineered to resemble Alzheimer’s disease, a human neurodegenerative disorder characterized by profound cognitive impairment.  Therefore, to test the hypothesis that the profile of  phosphorylated isoforms of GAP-43 are changed in the brains of a mouse used to model Alzheimer’s disease, GAP-43 will be examined by 1 and 2 dimensional SDS polyacrylamide gel electrophoresis.  Isoforms of mouse brain GAP-43 will be detected by immunocytochemistry and silver staining and, further, quantified by computerized densitometry.  Alterations in quantities of phosphorylated forms of GAP-43 might result from a pathological biochemical processes.  Revealing molecular defects generates potential targets for the development of possibly more effective drugs to combat dementia.
