Heatmap of relative expression of age-correlated genes

Relative expression of all genes selected as age-correlated based on polyserial correlation under conventional conditions is displayed as a heatmap across all conditions. Sample-level fold change (log₂) was calculated using the mean value for each gene in each condition, relative to the 30-d conventional condition. Data is presented organized by unsupervised clustering (pheatmap). Experimental condition is indicated at the bottom of each column; Y-axis represents 4577 genes. Color key for fold-change is shown at the upper right.
