Researchers have discovered a gene, OTUD7A, that impacts the development of Ewing sarcoma, a bone cancer that occurs mainly in children. They have also identified a compound that shows potential to block OTUD7A protein activity. Critical relationships between proteins contribute to the development of cancers such as Ewing sarcoma. So, it was a seminal discovery when the researchers found that OTUD7A controls the cancer-causing fusion protein.
