The agouti mouse model: an epigenetic biosensor for nutritional …
WEBThe viable yellow agouti (Avy) mouse model, in which coat color variation is correlated to epigenetic marks established early in development, has been used to investigate the impacts of nutritional and environmental influences on the fetal epigenome (Fig. 1A and B).
Agouti coloration genetics - Wikipedia
WEBAgouti works with extension to regulate the color of melanin which is produced in hairs. The agouti protein causes red to yellow pheomelanin to be produced, while the competing molecule α-MSH signals production of brown to black eumelanin. In wildtype mice, alternating cycles of agouti and α-MSH production cause agouti coloration. Each hair ...

WEBThe agouti (/ ə ˈ ɡ uː t iː /, ə-GOO-tee) or common agouti is any of several rodent species of the genus Dasyprocta. They are native to Middle America, northern and central South America, and the southern Lesser Antilles. Some species have also been introduced elsewhere in the West Indies. [1]

Step inside the lab of Dana Dolinoy at the University of Michigan, Ann Arbor, and you’re sure to hear conversations that include the rather strange word “agouti” (uh-goo-tee).
Nutrition & the Epigenome - University of Utah
WEBAll mammals have a gene called agouti. When a mouse's agouti gene is completely unmethylated, its coat is yellow and it is obese and prone diabetes and cancer. When the agouti gene is methylated (as it is in normal mice), the coat color is brown and the mouse has a low disease risk.

Agouti - an overview | ScienceDirect Topics
WEBThe term agouti refers to the gene in many mammals, including laboratory mice, that codes for fur coat color [178]. The wild-type agouti gene controls cell signaling at the base of the hair follicle; synthesizing either the black or brown eumelanin (a), or red or yellow pheomelanin (a) [178–180].
