Expression similarities among different species

A: Tissue expression similarities among humans, rhesus monkeys, tree shrews, and mice. Expression patterns in five tree shrew tissues more closely resembled that of primates than that of mice. B: Comparisons of protein sequence identity of genes in KEGG pathways between tree shrews and humans and between mice and humans. C: Expression patterns of genes in brain-related pathways in tree shrews, rhesus monkeys, humans, and mice. Brain-related pathways included “Alzheimer’s disease”, “Parkinson disease”, “Neuroactive ligand-receptor interaction”, “Pathways of neurodegeneration-multiple diseases”, and “Axon guidance”.
