Age-related changes in gene expression in RPE/choroid.

Shown are the differentially expressed genes in the 4 most significantly changed pathways in aged RPE/choroid by Limma analysis. Fold changes compare old vs. young. “No.” means the number of statistical methods (Limma, Dchip and SAM) in which each gene appeared changed. See Table S1 online for a complete list of gene expression changes in the RPE/choroid of old animals.
