Expression of stabilized β-catenin in differentiated neurons of transgenic mice does not result in tumor formation [PDF]

, 2002
Background: Medulloblastomas, embryonal tumors arising in the cerebellum, commonly contain mutations that activate Wnt signaling. To determine whether increased Wnt signaling in the adult CNS is sufficient to induce tumor formation, we created transgenic
