Fig. 3From: Differences in genome-wide gene expression response in peripheral blood mononuclear cells between young and old men upon caloric restrictionStepwise selection of genes in microarray analysis to identify genes in which expression changed from an old profile to a young profile upon 3 weeks of 30 % CR. For signal intensity, 12,783 genes were selected (≥5 in >5 arrays); from these, 96 genes were selected that were differently expressed between old and young men before CR (P < 0.05); the last part depicts number of genes that show a different response to CR in old versus young men. Finally, 23 genes with a significant change in expression within young (left track) men and 55 genes within old (right track) men are shownBack to article page
