Japanese researchers reveal cancer-causing gene

Japanese researchers have discovered a genetic factor related to different types of cancer. Reporting their findings in the Jan. 24 issue of Science Express, the researchers from Dana-Farber Cancer Institute and the Broad Institute said the highly “recurrent” mutations – occurring in the tumors of many people – may be the most common mutations in melanoma cells found to date. The researchers said these cancer-associated mutations are the first to be discovered in the vast regions of DNA in cancer cells that do not contain genetic instructions for making proteins. The mutations are located in non-protein-coding DNA that regulates the activity of genes.
