Establishment and Validation of a C57BL/6J Mouse Model for Melasma

Cell Proliferation, EarlyView.
A melasma‐like mouse model was established in C57BL/6J mice using a combination of UVB irradiation, progesterone administration, and chronic psychological stress. This model replicates key clinical features and biomarker alterations observed in human melasma. Importantly, it is fundamentally distinct from UV‐induced post‐inflammatory hyperpigmentation (

Biochemical characterization of proopiomelanocortin variants in human and owls [PDF]

, 2015
In humans the proopiomelanocortin (POMC) gene is located on the short arm of the chromosome 2 at the 23.3 position and encodes a 39kDa peptide with 241 amino acids. This peptide is the precursor of the proopiomelanocortin prohormone and it is produced in

Anti‐melanogenic effects of Medicago sativa seed extracts on melanocytes

International Journal of Cosmetic Science, EarlyView.
Our study demonstrated that two types of alfalfa seed extract: alfalfa ethanol precipitate (AEP) and alfalfa ethanol supernatant (AES) inhibited melanogenesis through the downregulation of tyrosinase expression, following the inactivation of CREB, b‐catenin and ERK signalling pathway in α‐melanocyte‐stimulating hormone (α‐MSH)‐stimulated B16F10 mouse ...

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

International Journal of Cosmetic Science, EarlyView.
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 ...

Structure elucidation of a human melanocortin-4 receptor specific orthosteric nanobody agonist

Nature Communications
The melanocortin receptor 4 (MC4R) belongs to the melanocortin receptor family of G-protein coupled receptors and is a key switch in the leptin-melanocortin molecular axis that controls hunger and satiety.

A Patient with Proopiomelanocortin Deficiency: An Increasingly Important Diagnosis to Make [PDF]

, 2017
Proopiomelanocortin (POMC) deficiency is a rare monogenic disorder with early-onset obesity. Investigation of this entity have increased our insight into the important role of the leptin-melanocortin pathway in energy balance. Here, we present a patient

MSC‐Derived Secretome and Exosomes in Dermatology: Mechanisms, Therapeutic Opportunities, and Scientific Challenges—A Narrative Review

International Journal of Dermatology, EarlyView.
ABSTRACT Mesenchymal stromal cells (MSCs) exert their effects primarily through paracrine signaling via soluble factors and extracellular vesicles (EVs), especially exosomes. These acellular components offer regenerative and immunomodulatory benefits with fewer safety and logistical constraints than cell‐based therapies.
