A more detailed analysis of eGFP expression, which can be used in our model as a reliable marker for ectopic Nanos3 expression, showed eGFP expression in both adenocarcinoma and bronchiolar neoplasia and confirmed the transcriptional activity of the CCSP promoter in the club cells of the bronchioles and in type-II cells of the alveoli. The gene discussed is SCGB1A1; the disease is adenocarcinoma.
