Transcription profiling of human HEK293 cells transfected with EWS-FLI1 (Ewing sarcoma family fusion gene)


ABSTRACT: Response of HEK293-cells after transfection with EWS-FLI1. HEK293 cells were transfected with the expression vector pIRES2-EGFP containing type I EWS-FLI1 or empty control vector. For transient transfection standard DEAE dextran method was used and RNA was isolated 48h post transfection. For stable transfection cells were transfected using FuGENE 6 (Roche, Mannheim, Germany) and cells were selected with 400 ug/mL G418. DNA-microarray analysis was performed using Affymetrix HG-U133A microarrays.(see Staege et al. Cancer Res. 2004)

Ewing family tumors (EFTs) are small round blue cell tumors that show features of neuroectodermal differentiation. However, the histogenetic origin of EFTs is still a matter of debate. We used high-density DNA microarrays for the identification of EFT-specific gene expression profiles in comparison with normal tissues of diverse origin. We identified 37 genes that are up-regulated in EFTs compared with normal tissues and validated expression of these genes in EFTs by both conventional and quanti  ...[more]
