N normal phenotype
respiratory system
• after 12 days of doxycycline (DOX) treatement, small, hyperplastic lung foci are detected; untreated mice have normal lungs
• after 5 weeks of DOX treatment, extensive epithelial hyperplasia of alveolar region of lung is observed; untreated mice have normal lungs
• alveolar lipoproteinosis is regularly found, indicating abnormal surfactant metabolism

neoplasm
• after 3 months treatment, visible macroscopic lesions are found; tumor incidence at 3 months is 55%, with multiplicity of 1.7 tumors/mouse
• lesions are <1mm in size
• early hyperplastic lesions are of alveologenic origin
• at 6 and 9 months DOX treatment, visible lesions increase in number; multiplicity is 10.2 and 12.5 tumors/mouse after 9 and 12 months, lower than Scgb1a1/KRAS bitransgenic mice; treated monotransgenic mice show no incidence
• when DOX treatment was stopped after 9 months, within 2 weeks only 4 tumors are visible on lung surface and by 1 month, no tumors are visible, and with minimal hyperplastic foci microscopically detectable, showing no proliferation (or apoptosis)

respiratory system
• after 12 days of doxycycline (DOX) treatement, small, hyperplastic lung foci are detected; untreated mice have normal lungs
• single adenoma was detected at 3 months; at 6, 9, and 12 months of treatment, incidence increases; mice develop higher incidence of proliferative changes with lower latency than SFTPC/KRAS mice
• at 12 months of treatment, 2 adenomas have progressed to low grade carcinomas
• after 5 weeks of DOX treatment, extensive epithelial hyperplasia of alveolar region of lung is observed; untreated mice have normal lungs

neoplasm
• after 3 months treatment, visible macroscopic lesions are found; tumor incidence at 3 months is 55%, with multiplicity of 3.5 tumors/mouse
• lesions are <1mm in size
• early hyperplastic lesions are of bronchiolar origin
• at 6 and 9 months DOX treatment, visible lesions increase in number; multiplicity is 28.8 and 34 tumors/mouse after 9 and 12 months, higher than SFTPC/KRAS bitransgenic mice; treated monotransgenic mice show no tumor incidence
• when DOX treatment was stopped after 9 months, within 2 weeks only 4 tumors are visible on lung surface; these remain after 1 months; minimal hyperplastic foci microscopically are detectable, showing no proliferation (or apoptosis)
• single adenoma was detected at 3 months; at 6, 9, and 12 months of treatment, incidence increases; mice develop higher incidence of proliferative changes with lower latency than SFTPC/KRAS mice
• at 12 months of treatment, 2 adenomas have progressed to low grade carcinomas
