• mammary tumor onset is accelerated in virgin females compared with either single Pten or single Erbb2 mutants, with tumor latencies of 6.5 compared with 15.3 months
• tumor progression is associated with loss of heterozygosity at the Pten locus in 50% of mutant mammary tumors
• tumors are similar to basal-like subtype of human breast cancer
