Genetic effects on coat colour in cattle: dilution of eumelanin and phaeomelanin pigments in an F2-Backcross Charolais x Holstein population [PDF]

open access: yes, 2007
Background: In cattle, the gene coding for the melanocortin receptor 1 (MCIR) is known to be the main regulator of the switch between the two coat colour pigments: eumelanin (black pigment) and phaeomelanin (red pigment).

Genetic Pigmentary Disorders: From Molecular Mechanisms to Clinical Manifestations

open access: yesThe Journal of Dermatology, Volume 53, Issue 2, Page 169-179, February 2026.
ABSTRACT Genetic pigmentary disorders represent a diverse group of genetic conditions characterized by alterations in melanin production and transport and melanocyte development, resulting from single‐gene pathological variants. These disorders encompass both hypopigmentary and hyperpigmentary phenotypes, affecting not only skin pigmentation but also ...

Melanin-based coloration in juvenile kestrels (Falco tinnunculus) covaries with anti-predatory personality traits [PDF]

open access: yes, 2012
Recent studies have shown that melanin-based coloration is associated with the ability to cope with stressful environments, potentially explaining why coloration covaries with anti-predator behaviours, boldness and docility.

Improved HPLC Conditions to Determine Eumelanin and Pheomelanin Contents in Biological Samples Using an Ion Pair Reagent

open access: yesInternational Journal of Molecular Sciences, 2020
Alkaline hydrogen peroxide oxidation (AHPO) of eumelanin and pheomelanin, two major classes of melanin pigments, affords pyrrole-2,3,5-tricarboxylic acid (PTCA), pyrrole-2,3-dicarboxylic acid (PDCA) and pyrrole-2,3,4,5-tetracarboxylic acid (PTeCA) from ...

A novel approach to target skin photodamage: Topical application of salt inducible kinase inhibitors

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 1, Page 1-15, February 2026.
UV‐induced photodamage leads to increased DNA damage and elevated MMP levels, which degrade collagen and contribute to wrinkle formation. SLT‐001 and SLT‐008, novel cosmetic ingredients that target salt‐inducible kinase, help reverse this effect by enhancing DNA repair, reducing MMP expression and decreasing erythema, thereby mitigating photodamage ...

Skin Lightening Treatments: A Review on the Effect of Intravenous Glutathione in the Disease States of Women [PDF]

open access: yes, 2020
The skin bleaching industry is a global business with a vast array of anti-melanogenic choices including glutathione. Glutathione is synthesized in vivo but has been used as a bodily supplement by medical personnel to aid in preventative medicine.

Deposition Mechanism and Properties of Thin Polydopamine Films for High Added Value Applications in Surface Science at the Nanoscale [PDF]

open access: yes, 2016
Polydopamine films have been introduced by Messersmith et al. as a possible “versatile” surface functionalization method allowing to coat the surface of almost all known materials even superhydrophobic surfaces.

Appearing as eumelanin or as pheomelanin and the push towards eumelanin by cysteine.

open access: yes, 2022
This report is a combination of new and former experimental results collected over the past three years. It details our observations and spectroscopic studies of the air-mediated oxidation of a wide variety of catecholic precursors into melanin-like materials. Depending on the precursor involved and the reaction conditions employed, dark-brown to black
