Peromyscus as a Mammalian Epigenetic Model

Abstract EN

Deer mice (Peromyscus) offer an opportunity for studying the effects of natural genetic/epigenetic variation with several advantages over other mammalian models.

These advantages include the ability to study natural genetic variation and behaviors not present in other models.

Moreover, their life histories in diverse habitats are well studied.

Peromyscus resources include genome sequencing in progress, a nascent genetic map, and >90,000 ESTs.

Here we review epigenetic studies and relevant areas of research involving Peromyscus models.

These include differences in epigenetic control between species and substance effects on behavior.

We also present new data on the epigenetic effects of diet on coat-color using a Peromyscus model of agouti overexpression.

We suggest that in terms of tying natural genetic variants with environmental effects in producing specific epigenetic effects, Peromyscus models have a great potential.
