Abstract:
PURPOSE:Increases in matrix proteins, such as type I collagen and fibronectin, are observed with aging in the retinal pigment epithelium (RPE) basement membrane. However, little is known about altered gene expression profiles of RPE associated with increases in matrix proteins. We investigated changes in gene expression profiles of a human RPE cell line (ARPE-19) cultured on type I collagen. METHODS:Visually confluent ARPE-19 cells were grown on either Matrigel (M group) or type I collagen (C group) without serum over 3 days. Total RNA was extracted and reverse transcribed. Gene expression profiles in both groups were compared using microarray analyses. Several angiogenic genes including integrin alpha V, integrin alpha 2, integrin beta 1, integrin beta 3, VEGF-A, VEGF-B, and VEGF-C were subjected to quantitative analyses using real-time PCR. RESULTS:Out of 192 genes examined, angiogenesis-related genes (17.7%) and extracellular matrix-related genes (30.2%) were expressed highly (with more than 1.5-fold difference) in the C group when compared with the M group. In real-time PCR analyses, all VEGF and integrin family genes examined were expressed more in the C group than in the M group. CONCLUSIONS:Type I collagen likely causes an upregulation in a number of angiogenic gene expression patterns as seen in RPE in vitro experiments.
