Conserved pathways of ageing in the brain
Genome-wide gene expression studies during ageing of the nematode
Caenorhabditis elegans, the common fruitfly (Drosophila melanogaster)
and the brains of mice, rats, chimpanzees and humans have
revealed a few broadly conserved functional categories of genes with
age-dependent expression changes6,19 (Table 2 and Fig. 2).
