Fig. 6: Venn diagram showing the number of differentially expressed genes observed in kidney, liver, and spleen tissue in the interspecies comparison between Spalax and rat kept at normoxic conditions.

A Genes showing higher expression in Spalax than in rat. B Genes showing lower in Spalax than in rat. Criterion for differential expression was a value of padj < 0.05. The large number of genes, which are differentially expressed in all three tissues, indicates across-organ adaptations on the gene regulatory level in Spalax compared to rat.
