respiratory system
• mice on a dox diet for 17.5 weeks of age develop a large lung tumor burden; these are heterogeneous adenocarcinomas involving the solid, bronchioalveolar, and papillary subtypes
• tumors of dox treated mice are negative for CC26, a Clara cell protein, and positive for surfactant protein-C, a type II pneumocyte marker, indicating a type II cell-like phenotype
• regression of tumors is seen as early as one week after removal of the inducer dox, however microscopic islands of tumor cells can still be seen even after mice are off dox for 4 weeks
• lung tumors of dox treated mice are resistant to treatment with erlotinib
• tumor bearing mice treated with the geldanamycin analogue, 17-AAG, which inhibits Hsp90, show tumor necrosis although viable tumor nodules remain
• however, mice maintained without dox exhibit normal lung morphology
• mice on a doxycycline (dox)-containing diet for 17.5 weeks become tachypneic
