Hierarchical clustering based on pseudogene expression shows pseudogene association with breast cancer subtypes. (A) Heatmap showing pseudogene expression profiles in tumor and adjacent normal samples. High expression levels are shown in light green, and low expression levels are shown in light blue. Tumor samples are highlighted in red along the top of the plot; adjacent normal samples are highlighted in green. (B) Heatmap of pseudogene expression profiles in tumor samples. Samples belonging to the basal subtype are highlighted in yellow along the top of the plot.
