Description: |
In most Western countries, the incidence of melanoma - a form of skin cancer linked to exposure to sunlight - doubles roughly every decade. Early removal of melanoma lesions leads to a good prognosis, but the outlook for patients with advanced melanoma is often bleak owing to a lack of effective treatments. To develop better therapies, a deeper understanding of this cancer's biology is needed. This article reports on a new use of a proteomics technique to identify molecules regulating melanoma-cell behaviour. [Source: Nature]
