Fig. 2From: Differences in genome-wide gene expression response in peripheral blood mononuclear cells between young and old men upon caloric restrictionCorrelation heat maps of CR-induced significant changes in gene expression of (A) genes regulated by upstream regulators in young, depicted for the response in young (A1) and old (A2), and of (B) genes regulated by upstream regulators in old, depicted for the response in young (B1) and old (B2). Scale: green = correlation score of −1, pink = correlation score of 1Back to article page
