Differential gene expression between day 1 foal, day 42 foal, and adult horse samples.

Gene expression levels were compared between groups and plotted with log2 fold expression on the x-axis and–log10 p-value on the y-axis. Gray lines show threshold for levels of differential expression (fold change ≥2) and significance (p-value <0.01). A) Comparison of gene expression from day 1 versus day 42 foal samples; B) comparison of gene expression from day 42 foal versus adult samples; and C) comparison of gene expression from day 1 foal versus adult samples.
