In the article entitled "Pathways Change in Expression During Replicative Aging in Saccharomyces cerevisiae," published in (J Gerontol A Biol Sci Med Sci. 2008;63A(1):21–34, authors Gloria Yiu, Alejandra McCord, Alison Wise, Rishi Jindal, Jennifer Hardee, Allen Kuo, Michelle Yuen Shimogawa, Laty Calhoun, Michelle Wu, John Kloke, Johanna Hardin, and Laura L. Mays Hoopes found a duplicated data set in the 8 generation array analysis. Substitution of the correct microarray data for the duplicate, and reanalysis, caused the following changes to the article:
Text: On page 24, in the first paragraph under Results, Series record GSE10018 should have been added to the reference to the Gene Expression Omnibus data deposit.
On page 25, first column, first paragraph (under Figure 3), the second sentence should read: "Our data indicate that for genes with p 
.05 (again, t tests of experimental condition vs control at 1g using the Holm correction), there are fewer than 30 genes with statistically significant changes in the 8g arrays."
Tables 2, 3, and 4: These tables contain two erroneous columns of data for 8 g arrays containing the mean and standard deviation at 8 g for each gene. Some of the other columns experienced very small corrections due to the normalization over the whole data set. The correct versions of Tables 2, 3, and 4 appear below.
Figure 1: Revised Figure 1 appears below.

Revised Figure 1. Overlap in statistically significant changes (p  .05) among age classes in microarray data. Using Bioconductor (22–24), the p values have been adjusted for multiple testing by the method of Holm (25). The number of genes whose expression was unchanged is shown in the lower right corner of each square
