Virus-based reporter systems for monitoring transcriptional activity of hypoxia-inducible factor 1.

ABSTRACT: Being key regulator of oxygen homeostasis hypoxia-inducible factor 1 (HIF-1) plays significant roles in cancer progression as well as in cardiovascular diseases. The modulation of HIF-1alpha activity in vivo may represent a valuable therapeutic approach to these disorders. In order to monitor HIF-1 transcriptional activity, we have developed HIF-1alpha-responsive reporter constructs, in which lacZ gene expression is driven by minimal Hsp70 gene promoter or minimal immediate early promoter of cytomegalovirus (CMV) and a combination of hypoxia response elements from regulatory regions of PGK1, ENO1 and LDHA genes. For the efficient delivery to a wide variety of cell types we chose retroviral and lentiviral vectors as carriers of the reporter cassette. We demonstrate that the obtained reporte
