respiratory system
• 3 and 6 months, adeno-cre-treated mice exhibit primary lung tumors with metastasis to the liver unlike wild-type mice
• at 3 and 6 month, adeno-cre-treated mice exhibit more tumors than in similarly treated Rb1tm3Tyj Trp53tm1Brn homozygotes
• adeno-cre-treated mice exhibit few lung adenocarcinomas, adenocarcinomas with neuroendocrine features, large-cell neuroendocrine carcinoma, and large-cell carcinomas while most tumors resemble neuroendocrine small-cell lung tumors
• most tumors in adeno-cre-treated mice resemble those found in human neuroendocrine small cell lung cancer patients

mortality/aging
• adeno-cre-treated mice begin to die at 17 weeks and by 6 months all mice are moribund
