Diet effects on cardiac gene expression. A: Experimental design and statistical model. Eight samples per diet group were hybridized onto Affymetrix 1.0ST GeneChip arrays. B: 2D heatmap of 6791 sex-specific cardiac genes (P < 0.01). C: 3D heatmap of standardized expression values of DEGs with an FDR adjusted ANOVA p-value of <.01 for sex and diet.
