The role of heme in retinal vascular development and disease
PROJECT ABSTRACT Retinal vascular diseases are major causes of vision loss in the United States and around the world. To better treat these disorders, we need to understand the signaling pathways that control the growth and integrity of retinal blood vessels. Our recent publications and preliminary data detail a novel angiogenic signaling system centered around heme, a co-factor critical for oxygen transport, metabolism, and gene transcription. We found that heme promotes angiogenic growth in the retina by regulating tip/stalk selection, and that reduced heme production or import leads to reduced retinal vascularization and tissue hypoxia, similar to other retinal vasculopathies including…
