Eumelanin protects the liver against diethylnitrosamine-induced liver injury.
Toxicology, 2022 This study aims to evaluate in vivo protective effects of eumelanin (EU) on diethylnitrosamine (DEN)-induced liver injury. Wistar albino male rats were divided into 6 groups (n=6), Control, DMSO, DEN, DEN+EU10, DEN+EU15, and DEN+EU20.

Splenic eumelanin differs from hair eumelanin in C57BL/6 mice.
Acta Biochimica Polonica, 2005 The presence of melanin in spleens of black C57BL/6 mice has been known for long. Although its origin and biological functions are still obscure, the relation of splenic melanin to the hair follicle and skin pigmentation was suggested. Here, we demonstrated using for the first time electron paramagnetic resonance spectroscopy that black-spotted C57BL/6

Elucidation of the hierarchical structure of natural eumelanins [PDF]
Journal of The Royal Society Interface, 2018 Eumelanin is one of the most ubiquitous pigments in living organisms and plays an important role in coloration and UV protection. Because eumelanin is highly cross-linked and insoluble in solvents, the chemical structure is still not completely known.
