The new model, which was created by knocking out a key component of the DNA repair machinery, will aid in exploring the genetic roots of this deadly brain cancer. The researchers, led by Howard Hughes Medical Institute investigator Frederick W. Alt, published their findings the week of April 24, 2006, in the early online edition of the Proceedings of the National Academy of Sciences. Catherine Yan, who is in Alt's laboratory at Children's Hospital Boston, was lead author of the article. Other co-authors were from Brigham & Women's Hospital, CBR Institute of Biomedical Research, Children's Hospital and Dana-Farber Cancer Institute, all of Harvard Medical School.
