JSRV, which causes sheep lung cancer, is known to have the transforming activity of NIH3T3 cells. Especially Envelope protein of this virus has the transforming activity to NIH3T3. To know the effects on the transcriptional activity of transcription factors by this viral protein transient transfection was performed by using the luciferase reporter system. The result showed that JSRV Envelope protein increased the transcriptional activity of NF-kB and AP-1.
