Abstract

A human fovea cDNA library was arrayed at high-density and reacted with age-specific (4 yr & 80 yr) retinal probes to identify genes with altered expression during aging. Using this approach, we screened 55,368 genes by Southern analysis and determined that ∼0.7% are differentially expressed in young and old tissues. Northern analysis of total RNA from retina of humans aged 2–94 yr show that expression of one of the clones identified (clone dd112) decreases with aging.
