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
WEBIn wildtype mice, alternating cycles of agouti and α-MSH production cause agouti coloration. Each hair has bands of yellow which grew during agouti production, and black which grew during α-MSH production. Wildtype mice also have light-colored bellies.
The Developmental Role of Agouti in Color Pattern Evolution
WEBFeb 25, 2011 · We took advantage of two locally camouflaged populations of Peromyscus mice to show that the negative regulator of adult pigmentation, Agouti, also plays a key developmental role in color pattern evolution.
Seeing ‘evolution in real time’: Mice blend in to survive
WEBJan 31, 2019 · A young, dark-colored deer mouse on dark soil studded with bright green grass. This rodent might be better camouflaged from birds of prey because it carries a functioning copy of the Agouti...
What is the Agouti Gene and How Does it Affect Coat Color in …
WEBDec 20, 2023 · The agouti gene is a gene that plays a crucial role in determining the coat color variation in mice. The gene controls the production and distribution of pigments in the hair follicles, resulting in different coat colors and patterns.
Mouse coat color mutations: From fancy mice to functional …
WEBMay 11, 2006 · A few years later, coat color mutations were used during the generation of the first inbred mouse strain, DBA (named according to the visible coat color mutations dilute (d), brown (b), and agouti (a) that it carries). This finding was a major development for the experimental use of mice.
Genetics, development and evolution of adaptive pigmentation in ...
WEBJul 5, 2006 · Pigmentation's utility as a visible phenotypic marker has resulted in over 100 years of intense study of coat color mutations in laboratory mice, thereby creating an impressive list of...
An enhancer of Agouti contributes to parallel evolution of …
WEBJul 2, 2022 · Dorsal coats range from dark brown in mainland mice to near white in mice inhabiting sandy beaches; this light pelage has evolved independently on Florida's Gulf and Atlantic coasts as camouflage from predators.
The Agouti mouse: a biosensor for environmental epigenomics
WEBThe Agouti mouse: a biosensor for environmental epigenomics studies investigating the developmental origins of health and disease. Epigenomics. 2014;6 (5):447-50. doi: 10.2217/epi.14.58. Author. Randy L Jirtle 1. Affiliation. 1 Department of Sport & Exercise Sciences, University of Bedfordshire, Bedford, UK. PMID: 25431934. DOI: 10.2217/epi.14.58.
WEBAt the phenotypic level, color can vary dramatically in the wild, can be measured straightforwardly, and can have clear links to fitness (e.g., Caro and Mallarino, 2019). One classic and extreme example of rapid color evolution involves the beach mice found in the southeastern United States.
