Genes up- and down-regulated by aging from 6 months to 24 months in rat kidney, liver, and gastrocnemius muscle, and the impact of RAD001 on the expression of these age-perturbed genes at 24 months. Rats aged 4.5 month and 22.5 months were treated with vehicle and rats aged 22.5 months were treated with RAD001 for 6 weeks, with a read-out at 6 and 24 months. Transcriptional profiling in the kidney, liver and gastrocnemius muscle was carried out by RNA-seq. Heat maps (A, B, C) depict genes that are differentially expressed between 6- and 24 month-old tissues (p < .05 adjusted for false discovery rate [FDR]) and the impact of RAD001 on the expression profile of these age-regulated genes. The blue hash (#) indicates genes that are significantly different between 6- and 24-month-old vehicle treated rats (p < .05 adjusted for FDR) and the red asterisk (*) indicates genes that are significantly different between 24-month-old vehicle treated and 24-month-old RAD001 treated rats (p < .05 adjusted for FDR). Standardized expression levels, from low to high, are colored from green to red: thus gene up-regulation is shown by a transition from green to red, and down regulation by a transition from red to green. In each heat map image, each column represents a single rat and each row represents a single gene. N = 8–10 rats per group.
