• 30% of hemizygous females expressing the transgene in a Sdc1tm1Cma heterozygous null background develop mammary tumors (median time: ~25 weeks) versus 34% of hemizygous females in a Sdc1 wild-type background (median time: ~21 weeks)
• these Wnt1-induced tumors are predominantly alveolar adenocarcinomas
