Earliest event in the development of sun-induced skin cancer identified
|
|
According to a new study from the University of Minnesota, the earliest event in the development of sun-induced skin cancer may have been identified. The researchers found that the point of entry for skin cancer in response to sun exposure is in receptor molecules, molecular "hooks" on the outer surface of cells that also pull cannabinoid compounds found in marijuana out of the bloodstream.

Previtamin D3 production varies depending on skin type and weather conditions
|
|
Researchers from Boston University School of Medicine (BUSM) have found that 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 ~35 degrees, there is minimal if any previtamin D3 production in the skin.

Researchers provided genetic evidence that ATF2 plays a suppressor role in skin cancer development
|
|
Researchers at the Burnham Institute for Medical Research (Burnham Institute) have provided genetic evidence that Activating Transcription Factor 2 (ATF2) plays a suppressor role in skin cancer development. ATF2 is a protein that regulates gene transcription, which is the first step in the translation of genetic code, in response to extracellular stresses such as ultraviolet light and ionizing radiation.

Deadly skin cancer called Merkel cell carcinoma Linked To Newly Discovered Virus
|
|
A new strategy to hunt for human viruses described in this week's issue of the journal Science by the husband-and-wife team who found the cause of Kaposi's sarcoma has revealed a previously unknown virus strongly associated with another rare but deadly skin cancer called Merkel cell carcinoma. In the paper, University of Pittsburgh Cancer Institute (UPCI) researchers, Huichen Feng, Ph.D., Masahiro Shuda, Ph.D., Yuan Chang, M.D., and Patrick Moore, M.D., M.P.H., explain a nearly decade-long effort to harness the sequencing technology to identify the virus, which they call Merkel cell polyomavirus (MCV). While the research team emphasizes that their work does not prove MCV to be the cause of Merkel cell carcinoma, if the findings are confirmed, they may lead to new cancer treatment and prevention options.
