May 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, researchers found that skin pigmentation alterations in a mouse model of Carney complex may be caused by specific dermal fibroblasts promoting melanogenic signaling.
November 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.
This study found that transgenic expression of Endothelin 3 in mice can maintain a dark pigmentation phenotype independently of Mc1r signaling by regulating melanogenic genes.
March 2013 in “Pigment Cell & Melanoma Research” This study revealed that different coat patterns in cats and cheetahs are related to variations in the aminopeptidase Q gene and endothelin-3 expression, which affects pigment production.
