A single-copy Sleeping Beauty transposon mutagenesis screen identifies new PTEN -cooperating tumor suppressor genes

Juan Cadiñanos and colleagues perform an insertional mutagenesis screen with a single-copy inactivating Sleeping Beauty transposon to look for Pten -cooperating tumor suppressor genes in mice. They find novel candidate cancer genes, verify their clinical relevance in patient cohorts and functionally demonstrate their synergistic relationship to Pten in tumor suppression.
