The bright and dark side of red hair pigments
, 2012 In recent years considerable structural, chemical, and photophysical insights into red hair pigments have yielded an unprecedented molecular basis to unravel their actual roles in the susceptibility of RHC phenotypes to photodamage and the oxidative ...

The coat color genes regulate eumelanin and pheomelanin synthesis in melanocytes
, 2012 In mice, eumelanin and pheomelanin synthesis is regulated by numerous coat color genes. Eumelanin and pheomelanin contents were measured in cultured melanocytes and in the epidermis/dermis and hairs of C57BL/10JHir (B10) and its congenic mice carrying ...

The Ultraviolet Absorption Coefficient of Melanosomes Decreases with Increasing Pheomelanin Content
, 2010 Uveal melanosomes from the iridal stroma contain both eumelanin and pheomelanin, the ratio of which varies with iris color. Herein, we report the absorption coefficient at lambda = 244 nm for individual human iridal stroma melanosomes from dark brown and
