Abstract
Lung cancer is a leading cause of tumor-related deaths in humans but its origin and development are poorly understood. To study the biology of these tumors, appropriate animal and cell culture models will be of eminent importance. Uteroglobin is a marker protein for the nonciliated epithelial Clara cells lining the respiratory and terminal bronchioli of the lung. We have used the promoter and 5'-flanking sequences of the rabbit uteroglobin gene to target expression of the SV40 T antigen to the lung of transgenic mice. All transgenic founders as well as the descendants from an established line, UT7.1, developed multifocal bronchioloalveolar adenocarcinomas originating from Clara cells. At least three different stages in tumor development with progressive loss of the differentiated phenotype can be distinguished by immunohistochemcial data and in situ hybridzation.
