Disrupted endothelial junctions in tumor vessels of Epn1tm1.1Wami/Epn1tm1.1Wami Epn2tm1Ocr/Epn2tm1Ocr Tg(Cdh5-cre/ERT2)CIVE23Mlia/0 mice

mortality/aging
decreased susceptibility to induced morbidity/mortality ( J:193966 )
• tamoxifen-treated mice transplanted with GL261glioma cells survive longer than with control mice

neoplasm
abnormal tumor vascularization ( J:193966 )
• tamoxifen-treated mice transplanted with Lewis Lung carcinoma (LLC) cells exhibit disorganized, fragile, immature, enlarged and leaky tumor vessels compared with control mice

decreased incidence of tumors by chemical induction ( J:193966 )
• tamoxifen-treated mice subjected to AOM/DSS exhibit reduced tumor incidence and decreased tumor growth compared with control mice
decreased tumor growth/size ( J:193966 )
• tamoxifen-treated mice transplanted with Lewis Lung carcinoma (LLC) cells develop fewer, smaller tumors that grow at a slower rate compared with control mice
• tamoxifen-treated mice transplanted with GL261glioma cells develop smaller tumors compared with control mice
• tamoxifen-treated mice subjected to AOM/DSS exhibit reduced tumor incidence and decreased tumor growth compared with control mice

cardiovascular system
abnormal tumor vascularization ( J:193966 )
