Abstract
Development of methods for gene transfer into specific cell types or tissues is important for experimental research as well as clinical therapeutical approaches. We report here the cloning and characterization of the envelope (env) gene and the U3 region of a retrovirus from an infected human Small Cell Lung Cancer (SCLC) cell line. The replication of this murine retrovirus is also fully supported by other lung cancer cell lines of different histological origin. We present evidence that a long terminal repeat (LTR)-beta-galactosidase (beta-Gal) reporter construct performed as well as an analogous cytomegalovirus (CMV) promoter beta-Gal construct in the human lung epithelial cell line A549 and in the human larynx carcinoma cell line HEp2.
