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.
