Figure 6

Heatmap of differentially expressed genes (DEGs) in different sample types compared with non-malignant prostate tissue samples. The heatmap and column dendrogram were used to visualise the variances in DEGs across the sample groups based on the average of logarithmic scale base two (log2) fold change. The log2 fold change is displayed on the right side, varying from −11.95 to 11.96. On the right side, Ensembl ID and official gene names show cancer-related genes (e.g., MYC, MKI67) and genes that were linked to canine prostate diseases (e.g., NKX3-1, KLK4, ACPP) in the heatmap.
