neoplasm
increased mammary gland tumor incidence ( J:133325 )
• tumor nodules are present throughout the entire mammary gland
• combination of adenomas and cystic hyperplasias are seen in mammary glands
• tumor angiogenesis assessed by microvessel density is significantly decreaed relative to tumors from Tg(MMTV-PyVT)634Mul single mutants, along with increased level of ischemic necrosis
decreased metastatic potential ( J:133325 )
• number of mice displaying lung metastases is decreased compared to Tg(MMTV-PyVT)634Mul single mutants (58 vs 91 mice)
increased tumor latency ( J:133325 )
• mammary tumor onset is modestly delayed compared to Tg(MMTV-PyVT)634Mul single mutants (86 days vs 66 days)
