Gene expression profile of long-lived Ames dwarf mice and Little mice.

Abstract excerpt

Ames dwarf mice (Prop1df/df) and Little mice (Ghrhrlit/lit) are used as models of delayed aging and show significant increases in lifespan (50% and 25%, respectively) when compared with their wild-type siblings. To gain further insight into the molecular basis for the extended longevity of these mice, we used oligonucleotide microarrays to measure levels of expression of over 14 000 RNA transcripts in liver...
