The retinal pigment epithelium (RPE) is a monolayer of cells located directly behind the photoreceptor cells in the retina. These cells are involved in a variety of functions that support the visual process in the eye, namely 1) they form a blood-retina barrier which separates the neural retina from the choroid's blood supply, 2) the apical processes of RPE cells diurnally phagocytose the outer segments of photoreceptor cells, and 3) they participate in the renewal of the photopigment 11-cis retinal. Age-related macular degneration (AMD) is the leading cause of blindness in people over the age of 50 years in North …

Undergraduate Honors Capstone Projects
Ferritin is the iron storage protein found in humans, animals, plants, fungi and bacteria. We are interested in how iron is loaded and stored in mammalian ferritin. Ferrous iron must be oxidized to ferric iron in order to be stored in ferritin. It is generally believed that ferritin does the loading itself, dependant upon a "ferroxidase activity." Oxidation of iron can result in the production of the hydroxyl radical which can cause oxidative damage to surrounding proteins and other biomolecules. An indicator of oxidative damage to proteins is the formation of carbonyl groups. Using only the H subunit of human …
