Sequence characterization and polymorphism of melanocortin 1 receptor gene in some goat breeds with different coat color of Mongolia [PDF]

Asian-Australasian Journal of Animal Sciences, 2019
Objective Extension and Agouti loci play a key role for proportions of eumelanin and pheomelanin in determining coat color in several species, including goat. Mongolian goats exhibit diverse types of coat color phenotypes. In this study, investigation of

Preliminary study on MC1R polymorphism in some cattle breeds raised in Italy

Italian Journal of Animal Science, 2011
Most of the Western European cattle breeds consist of standardised breeds with a definite coat colour (Renieri et al., 1984). Thus coat colour could be useful to detect genetic markers for cattle breed identification.

Photobleaching of pheomelanin increases its phototoxic potential: Physicochemical studies of synthetic pheomelanin subjected to aerobic photolysis

Pigment Cell & Melanoma Research, 2018
AbstractAlthough melanin is a photoprotective pigment, its elevated photochemical reactivity could lead to various phototoxic processes. Photoreactivity of synthetic pheomelanin, derived from 5‐S‐cysteinyldopa (5SCD‐M) and its photodegradation products obtained by subjecting the melanin to aerobic irradiation with UV‐visible light, was examined ...

Agouti protein, mahogunin, and attractin in pheomelanogenesis and melanoblast-like alteration of melanocytes: a cAMP-independent pathway

, 2009
Melanocortin-1 receptor (MC1R) and its ligands, a-melanocyte stimulating hormone (aMSH) and agouti signaling protein (ASIP), regulate switching between eumelanin and pheomelanin synthesis in melanocytes.

Thin Amelanotic and Hypomelanotic Melanoma: Clinicopathological and Dermoscopic Features

Medicina
Background and Objectives: Amelanotic/hypomelanotic melanomas (AHMs) account for 2–8% of all cutaneous melanomas. Due to their clinical appearance and the lack of specific dermoscopic indicators, AHMs are challenging to diagnose, particularly in thinner ...

Sexual dimorphism in melanin pigmentation, feather coloration and its heritability in the barn swallow (Hirundo rustica). [PDF]

PLoS ONE, 2013
Melanin is the main pigment in animal coloration and considerable variation in the concentrations of the two melanin forms (pheo- and eumlanin) in pigmented tissues exists among populations and individuals.

Beyond Molecular Determinism: State‐Convergent Polymerization as a Functional Design Principle Under Chemical Complexity

Advanced Science, EarlyView.
This work introduces state‐convergent polymerization (SCP), a polymerization framework in which chemically diverse reaction pathways converge toward a reproducible functional polymeric state rather than a defined molecular structure. Using melanin and polydopamine as exemplars, SCP explains how robust polymer functions emerge under chemical and ...
