Coloration in Equine: Overview of Candidate Genes Associated with Coat Color Phenotypes

Animals
Variation in coat color among equids has attracted significant interest in genetics and breeding research. The range of colors is primarily determined by the type, concentration, and distribution of melanin pigments, with the balance between eumelanin ...

Pheomelanin Pigment Is Not an Indicator of Feather Corticosterone Content in Diurnal Migratory Raptors in Idaho

, 2016
In some cases, pigmentation can be used as an indicator of measures of condition. In this study, I tested the relationship between reddish pheomelanin pigmentation and the amount of corticosterone, a hormone associated with stress, sequestered in the ...

Eumelanin and pheomelanin concentrations in human epidermis before and after UVB irradiation

Pheomelanin is widely thought to be causally related to susceptibility to the harmful effects of ultraviolet radiation: epidemiological studies show that those with a higher ratio of pheomelanin to eumelanin in hair have higher rates of melanoma, and ...

Excess tyrosine stimulates eumelanin and pheomelanin synthesis in cultured slaty melanocytes from neonatal mouse epidermis

, 2007
Mouse slaty (Dctslt) mutation is known to reduce the activity of dopachrome tautomerase (DCT). The reduced DCT activity inhibits melanosome maturation and reduces the melanin content in the skin, hairs and eyes.
