Expression data of bronchoalveolar lavage cells from control or urethane treated AJ mice. Mus musculus

AJ mouse is susceptible to lung carcinogenesis from urethane treatment and is a good model for human adenocarcinoma. We completed a study using microarray analysis of bronchoalveolar lavage cells from control or urethane treated mice. A unique macrophage expression signature in the lung tumor microenvironment was able to correctly classify the lavage samples. Keywords: AJ mouse control and urethane treatment carcinogenesis protocol Overall design: RNA from bronchoalveolar lavage cells of age matched untreated AJ mice controls (C) or from urethane treated (T) AJ mice was prepared. Datasets were accurately classified using a unique macrophage gene expression signature derived from the tumor microenvironment.
