Promising target for the development of novel drugs With the X-ray vision of DESY's light source DORIS, a research team from Hamburg and Iceland has uncovered the molecular structure of a master regulator central to the most deadly form of skin cancer, melanoma. The results, published in the scientific journal "Genes & Development", throw new light on the workings of the so-called Microphthalmia-associated Transcription Factor MITF, that is not only connected to skin cancer, but also...

(Ivanhoe Newswire) -- Scientists have discovered a more effective alternative to skin whitening creams, and it comes from an ancient Chinese herb. Skin whitening is popular in countries like China, Japan, Korea and India, where many women view whiter skin as a symbol of beauty, good health and high social status. According to one study, about half the women in Asian countries use lightening creams. This adds up to billions of dollars a year. Many whitening creams and lotions contain...

Have you seen a spotted plaice? Probably. However, marine biologist Helen Nilsson Sköld at the University of Gothenburg is the first person to research the spotted insides of plaice. Many species of animal have skin or fur with intricate pigmentation patterns, which they use for camouflage, communication, regulation of body heat and protection against the sun. A study conducted by researchers at the Department of Marine Ecology at the University of Gothenburg has found that several...

The source and mechanisms underlying the abnormal heart beats that initiate atrial fibrillation (Afib), the most common type of abnormal heart beat, have not been well determined. However, a group of researchers at the University of Pennsylvania, Philadelphia, has now identified a population of cells that are like pigment producing cells in the skin (melanocytes) in the atria of the heart and pulmonary veins of mice and humans and uncovered evidence in mice that these cells contribute to...

By Abdel-Malek, Zalfa A Knittel, James; Kadekaro, Ana Luisa; Swope, Viki B; Starner, Renny ABSTRACT Cutaneous pigmentation is the major photoprotective mechanism against the carcinogenic and aging effects of UV. Epidermal melanocytes synthesize the pigment melanin, in the form of eumelanin or pheomelanin. Synthesis of the photoprotective eumelanin by human melanocytes is regulated mainly by the melanocortins alpha- melanocortin (alpha-MSH) and adrenocorticotropic hormone (ACTH), which bind...

WASHINGTON, D.C. -- A Duke University chemist has found differences in how ultraviolet light affects the photochemistry of human pigments that he says may explain why red-haired people are more prone to skin cancer than those with black hair. Duke chemistry professor John Simon and his collaborators used a broadly-tunable ultraviolet laser and a special microscope to distinguish between the oxidation potentials of pigments of redheaded and black-haired people. Oxidation potentials measure how...
