Abstract

DESCRIPTION (provided by applicant): Although vision loss in primary open angle glaucoma (POAG) results from retinal ganglion cell (RGC) death, the mechanistic basis for early and progressive RGC loss is unknown. With the aging population and increasing prevalence of glaucoma, there is an urgent need to elucidate the pathophysiology of RGC loss at both the molecular and cellular levels to develop medications that specifically address RGC loss in treating POAG patients. My research goal is to identify a molecular pathway by studying how RGC loss result from mutations in optineurin, which has been associated with familial normal pressure POAG in human genetic studies. We will investigate optineurin's novel role in regulating NF-:B activity and determine how mutations alter its normal function. The data from this research proposal are expected to reveal a defective biochemical pathway that lead to RGC death, which will facilitate the identification of specific targets for developing novel therapeutic or diagnostic approaches in POAG.
