The retinal pigment epithelium (RPE) plays a critical role in the development and maintenance of adjacent photoreceptors in the vertebrate retina. This study describes the development and characterization of ARPE-19, a spontaneously arising human RPE cell line with normal karyology which forms polarized epithelial monolayers on porous filter supports. The(More)
PURPOSE To determine the polarity of fibroblast growth factor 5 (FGF5) secretions from retinal pigment epithelium (RPE) cells and to examine the viability and utility of the ARPE-19 cell line as a model for the study of RPE polarity. METHODS Influenza infection and adenovirus-mediated gene transfer were used to deliver and express genes encoding influenza(More)
Inflammation results in heightened mitochondrial ceramide levels, which cause electron transport chain dysfunction, elevates reactive oxygen species, and increases apoptosis. As mitochondria in aged hearts also display many of these characteristics, we hypothesized that mitochondrial decay stems partly from an age-related ceramidosis that heretofore has not(More)
