Abstract

Piggybacking on Cancer Genes Transposons are mobile segments of DNA that can insert in or near important genes to cause mutations that disrupt gene function. Rad et al. (p. 1104 , published online 14 October) adapted a mutagenic transposon called Piggybac, originally derived from a moth, into a tool for discovery of cancer-causing genes in mice. Mobilization of Piggybac in mice was associated with the development of leukemias and solid tumors. In many instances the causative mutations, which were identified by mapping the Piggybac integration sites, were within genes not previously implicated in cancer.
