Low melanin level in white skin results in many genetic alterations that activate oncogenes to form metastatic melanomas because of interaction with ultraviolet rays. These melanomas are uncommon, but they are dangerous and spread rapidly in the individual's body. Individuals with fair, freckled ...

Psychological stress is a crucial factor in the development of many skin diseases, and the stigma caused by skin disorders may further increase the psychological burden, forming a vicious cycle of psychological stress leading to skin diseases. Therefore, understanding the relationship between stress and...
Retinal response to the acute hypoxia and reoxygenation were shown to be independent of melanin presence in the eye pigmental epithelium (PE), i.e. in the retinas of both pigmented animals and albinos hypoxia survived an increase in the content of hydroperoxidases and malonyl dialdehyde; subsequ...
We previously developed a quantitative autoradiographic technique with special forceps for measuring unscheduled DNA synthesis (UDS) in mouse skin after treatment with ultraviolet light in vivo. By this method, we investigated the relationship between the protective role of melanin and UV-induced DNA re...
Moreover, it has been observed that skin cells are also exposed to reactive oxygen species generated during cell metabolism particularly in relation to the synthesis of melanin or the metabolism in immune system cells. However, skin cells have special features that protect them against oxidative ...
To address more specifically the role of melanin in fair-skinned individuals, experiments were done with cells obtained from human skin of low phototypes (II-III). To study the effect of constitutive melanin and possibly that of...doi:10.1016/j.jid.2017.07.293Nesmond, S....
Over the last decade, there has been much research on the role of hypothalamic POMC neurones, with regard to appetite. However, POMC products (the MSHs, ACTH and β-endorphin) also have important roles in the skin, stress response, immune system and sexual function [1–6]. Experimental ev...
