| Abstract |
We previously reported the successful establishment of multiple immortalized cell lines that preserved the original nature of the primary cells via co-expression of R24C mutant cyclin-dependent kinase 4 (CDK4R24C), Cyclin D1, and telomerase reverse transcriptase (TERT). However, as these genes are kind of oncogenes, tools to control their expression levels are favorable. In this study, we describe a new polycistronic lentiviral vector expressing proliferation factors, CDK4R24C and Cyclin D1 along with enhanced green fluorescence protein (EGFP) under the control of doxycycline (Dox)-dependent transactivator (rtTA) and tetracycline response element (TRE). By introducing the Dox-inducible lentiviral vector into human airway epithelial cells, we established a novel human airway epithelial cell line harboring polycistronic Dox-inducible CDK4R24C and Cyclin D1, referred to as Tet-on K4D cells. We showed that the cell growth of Tet-on K4D cells could be controlled by Dox. Furthermore, expression of K4D genes and rtTA gene can be independently monitored by fluorescent imaging. Cultured airway epithelial cells are useful as a tool for studying the pathogenesis of lung disorders. Altogether, our established human airway epithelial cells could be used for a variety of studies such as lung pathology and biology underlying the differentiation process to form the complex pseudostratified multicellular layers.
