Rhabdomyosarcomas derive from the skeletal muscle lineage and harbor a variety of genetic and molecular lesions. However, it is not clear which molecular alterations have a pathogenetic role. We show that activation of the HER-2/neu oncogene coupled with inactivation of the oncosuppressor gene p53 causes rhabdomyosarcoma in mice. At the age of 11-21 weeks, all male mice carrying both genetic lesions developed embryonal rhabdomyosarcomas expressing desmin, myosin, and insulin-like growth factor-II, in the genitourinary tract. Our findings led to the hypothesis that the interaction between HER family genes and the p53 pathway might be involved in the origin of human rhabdomyosarcoma.
