Skin color is one of the most visible indicators that helps distinguish human appearance, and a new study provides more detail as to how one protein helps produce this wide palette. In 2005 researchers identified a gene called SLC24A5 as a key determinant of skin color. Scientists now confirm that the protein product of this gene (NCKX5) is an ion exchanger; it exchanges sodium for calcium across a membrane, regulated by potassium.

A new study on effects of mobile phone radiation on human skin strengthens the results of the human cell line analyses: living tissue responds to mobile phone radiation. Earlier studies have shown that mobile phone radiation alters protein expression and activity in human endothelial cell line. This new study is unique, because for the first time it has examined whether a local exposure of human skin to RF-EMF will cause changes in protein expression in living people.

Previtamin D3 production varies depending on several factors including skin type and weather conditions. Excessive exposure to sunlight does not result in Vitamin D intoxification because previtamin D3 and vitamin D3 are photolyzed to several photoproducts. During the winter at latitudes above approximately 35 degrees, there is minimal if any previtamin D3 production in the skin.

Plastic surgeons are beginning to deploy a new type of laser that goes deeper into the skin to help reduce wrinkles, tighten surface structures and treat pigmentation differences. Plastic surgeons at UT Southwestern have completed testing and are now starting to use the new carbon dioxide-based fractional laser, which combines minute focused columns of laser-induced injury with heat deposition for less skin damage and quicker recovery time.

It sounds too good to be true … a little inexpensive pill that could block the development of some cancers, strengthen bones, prevent multiple sclerosis and alleviate winter depression. But it’s not science fiction. The “new aspirin” could be Vitamin D. Just as we discovered that aspirin can guard against heart disease, Vitamin D could become a useful weapon in the fight against MS, osteoporosis, mild depression and one of the most devastating diseases of our time — cancer.

Researchers have taken a major step toward eventually being able to reprogram adult cells to an embryonic stem cell-like state without the use of viruses or cancer-causing genes. In a new paper, the researchers report that they have discovered how long adult cells need to be exposed to reprogramming factors before they convert to an embryonic-like state, and have “defined the sequence of events that occur during reprogramming.”

A tattoo can be more than just a fashion statement — it has potential medical value, according to a new article. Tattooing is a more effective way of delivering DNA vaccines than intramuscular injection.

Chemical peels using either alpha-hydroxy acid or beta-hydroxy acid are both highly effective in treating mild to moderately severe facial acne, researchers have found — the first study to compare the two different types of acid peels as therapies for the skin disorder. Peels using beta-hydroxy acid (or BHA) had slightly fewer side effects and results that lasted a bit longer than did peels using alpha-hydroxy acid (or AHA), the study found.

Genetic evidence has been provided that Activating Transcription Factor 2 plays a suppressor role in skin cancer development. ATF2 is a protein that regulates gene transcription, the first step in the translation of genetic code, in response to extracellular stresses such as ultraviolet light and ionizing radiation. This function of ATF2 in stress and DNA damage response suggests it may also play a role in tumor formation.
