N normal phenotype
cellular
• MEFs treated with adeno-cre and later with tamoxifen
• increased cell proliferation
• more cells at the G2/M phase of the cell cycle
• foci formation in 3D cell culture after tamoxifen treatment
• withdrawal of tamoxifen reduces colony formation

neoplasm
• mice treated with adeno-cre at 6-8 weeks of age and tamoxifen starting three weeks later
• tamoxifen doses of 100ug/mouse, 250ug/mouse, or 1000ug/mouse resulted in no lung abnormalities
• the intermediate dose of 500ug/mouse results in lung hyperplasia starting after 5 weeks of treatment
• lung adenomas found after 8 weeks of treatment
• tamoxifen treatment discontinued after 12 weeks and lung hyperplasia is decreased a weeks later
• lungs are normal 2 weeks after discontinuation of tamoxifen treatment

respiratory system
• mice treated with adeno-cre at 6-8 weeks of age and tamoxifen starting three weeks later
• tamoxifen doses of 100ug/mouse, 250ug/mouse, or 1000ug/mouse resulted in no lung abnormalities
• the intermediate dose of 500ug/mouse results in lung hyperplasia starting after 5 weeks of treatment
• lung adenomas found after 8 weeks of treatment
• tamoxifen treatment discontinued after 12 weeks and lung hyperplasia is decreased a weeks later
• lungs are normal 2 weeks after discontinuation of tamoxifen treatment
