Genetic Pigmentary Disorders: From Molecular Mechanisms to Clinical Manifestations

The 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 ...

Dominant Red Coat Color in Holstein Cattle Is Associated with a Missense Mutation in the Coatomer Protein Complex, Subunit Alpha (COPA) Gene. [PDF]

PLoS ONE, 2015
Coat color in Holstein dairy cattle is primarily controlled by the melanocortin 1 receptor (MC1R) gene, a central determinant of black (eumelanin) vs. red/brown pheomelanin synthesis across animal species. The major MC1R alleles in Holsteins are Dominant

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

International 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 ...

QUILPEN Provides Independent and Label‐Free Single‐Cell Quantification of Pigmentation Dynamics and Organelle Content

Pigment Cell &Melanoma Research, Volume 39, Issue 2, February 2026.
Pigment‐associated cellular features, such as melanin levels and organelles, can be quantified in live cells with label‐free multimodal imaging. Quantitative phase imaging (cyan) measures cell mass, scattering (yellow) reports organelle content, including melanosomes, and absorbance imaging (magenta) captures pigment such as melanin.

Sustainable Development Path of Traditional High-Pollution Bleaching Process for Animal Fibers: Key Mechanisms, Critical Influencing Factors and Bottlenecks—A Review

Journal of Natural Fibers
Animal fiber is an important raw material for textiles. Dark animal fibers cannot be directly dyed by light colors, which is difficult to meet the demand for color diversity in clothing.

A UV-Independent Topical Small-Molecule Approach for Melanin Production in Human Skin

Cell Reports, 2017
The presence of dark melanin (eumelanin) within human epidermis represents one of the strongest predictors of low skin cancer risk. Topical rescue of eumelanin synthesis, previously achieved in “redhaired” Mc1r-deficient mice, demonstrated significant ...

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Eumelanin electrodes in buffered aqueous media at different pH values

, 2020
Eumelanin, a quinone-based biomacromolecule, is the most common form of the biopigment melanin in the human body. Eumelanin has attracted great interest due to its physicochemical properties, such as metal-ion chelation, free radical scavenging ...
